     DETAILED DESCRIPTION 
     The exemplary embodiments will now be described more fully hereinafter with reference to the accompanying drawings. The exemplary embodiments may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete and will fully convey the exemplary embodiments to those of ordinary skill in the art. Moreover, all statements herein reciting embodiments, as well as specific examples thereof, are intended to encompass both structural and functional equivalents thereof. Additionally, it is intended that such equivalents include both currently known equivalents as well as equivalents developed in the future (i.e., any elements developed that perform the same function, regardless of structure). 
     Thus, for example, it will be appreciated by those of ordinary skill in the art that the diagrams, schematics, illustrations, and the like represent conceptual views or processes illustrating the exemplary embodiments. The functions of the various elements shown in the figures may be provided through the use of dedicated hardware as well as hardware capable of executing associated software. Those of ordinary skill in the art further understand that the exemplary hardware, software, processes, methods, and/or operating systems described herein are for illustrative purposes and, thus, are not intended to be limited to any particular named manufacturer. 
     As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless expressly stated otherwise. It will be further understood that the terms “includes,” “comprises,” “including,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. It will be understood that when an element is referred to as being “connected” or “coupled” to another element, it can be directly connected or coupled to the other element or intervening elements may be present. Furthermore, “connected” or “coupled” as used herein may include wirelessly connected or coupled. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. 
     It will also be understood that, although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first device could be termed a second device, and, similarly, a second device could be termed a first device without departing from the teachings of the disclosure. 
       FIG. 1  is a simplified schematic illustrating an environment in which exemplary embodiments may be implemented.  FIG. 1  illustrates a client-server network architecture that personalizes haptic renderings of merchandise. A client device  22  communicates with a server  20  via a communications network  24 . If a user of the client device  22  wishes to “touch and feel” merchandise (such as a bracelet, dress, watch, or other item), the client device  22  retrieves a haptic scan of the merchandise. That is, the client device  22  queries the server  20  for a haptic file  26  that describes haptic data  28  associated with the merchandise. The client device  22  receives the haptic file  26  and sends the haptic file  26  to a haptic emulator unit  30 . The haptic emulator unit  30  processes the haptic data  28  to produce a haptic, tactile sensation for the user. The haptic emulator unit  30  thus reproduces the “touch and feel” of the merchandise, allowing the user to sense texture, contour, and other haptic effects. Haptic emulation is generally known to those of ordinary skill in the art, so this disclosure will not greatly describe the known aspects. 
     Exemplary embodiments, though, personalize the haptic emulation. Before the haptic emulator unit  30  renders the haptic data  28  in the haptic file  26 , the client device  22  may retrieve the user&#39;s personalized anthropometrical data  32 . The anthropometrical data  32  describes the physical, two-dimensional or three-dimensional measurements of the user&#39;s various body parts. The anthropometrical data  32 , for example, may dimensionally describe the user&#39;s hand, arm, head, leg, and/or torso. The anthropometrical data  32  may even dimensionally describe the user&#39;s whole body, including weight, height, body mass, hair color, skin color, eye color, and any other features. Whatever the anthropometrical data  32 , the client device  22  retrieves the user&#39;s personalized anthropometrical data  32 . The client device  22  may then process the haptic data  28  in the haptic file  26  using the user&#39;s personalized anthropometrical data  32 . For example, the client device  22  instructs the haptic emulator unit  30  to render the haptic data  28  according to the user&#39;s personalized anthropometrical data  32 . That is, the haptic emulator unit  30  reproduces the “touch and feel” of the merchandise, but the haptic effect is personalized to the user&#39;s personal dimensions. 
     Exemplary embodiments thus personalize haptic emulations. The “touch and feel” of a bracelet, for example, is generated to custom-fit the user&#39;s wrist. Rings may be sized to the user&#39;s desired finger. Emulations of shirts, dresses, pants, and shoes may be tailored to the actual sizes of the user&#39;s corresponding body dimensions. Conventional haptic scans of merchandise are abstract and non-personal. Exemplary embodiments, though, combine the haptic data  28  with the user&#39;s personal measurements, thus customizing emulations for an accurate dimensional result. 
     Exemplary embodiments greatly enhance electronic commerce. When the user shops online for merchandise, exemplary embodiments allow users to experience the actual touch and feel of the merchandise in their correct sizes. Clothing may dimensioned for an accurate fit to the user&#39;s anthropometrical data  32 . The user may compare different standard sizes of clothing to their actual body dimensions. Jewelry may be tactilely emulated using the actual dimensions of the user&#39;s neck, ears, and head. Personalized haptic emulations will thus be attractive to potential buyers. Merchants will see increased sales, increased customer satisfaction, and reduced returns due to ill-fitting merchandise. 
     Consider a common example of clothing. Haptic scans of objects (such as a shirt or blouse) downloaded from an Internet catalog are inherently abstract and not tailor-made per each user. If the user only desires the mere “touch and feel” of the clothing, the lone haptic data  28  may be adequate. However, if the user wishes to virtually “try on” the clothing, customization is needed for accurate haptic rendering. Exemplary embodiments produce virtual merchandise worn over the virtual body parts of the user. The user is thus able to appraise its visual, tactual, as well as its haptic/physical properties (i.e., how a bracelet feels as it is moved against the hand) for a more fulfilling experience. 
     Exemplary embodiments may be applied regardless of network environment. The communications network  24  may be a cable network operating in the radio-frequency domain and/or the Internet Protocol (IP) domain. The communications network  24 , however, may also include a distributed computing network, such as the Internet (sometimes alternatively known as the “World Wide Web”), an intranet, a local-area network (LAN), and/or a wide-area network (WAN). The communications network  24  may include coaxial cables, copper wires, fiber optic lines, and/or hybrid-coaxial lines. The communications network  24  may even include wireless portions utilizing any portion of the electromagnetic spectrum and any signaling standard (such as the I.E.E.E. 802 family of standards, GSM/CDMA/TDMA or any cellular standard, and/or the ISM band). The communications network  24  may even include powerline portions, in which signals are communicated via electrical wiring. The concepts described herein may be applied to any wireless/wireline communications network, regardless of physical componentry, physical configuration, or communications standard(s). 
       FIGS. 2-3  are more detailed schematics illustrating the operating environment, according to exemplary embodiments. Here the server  20  has a processor  40  (e.g., “μP”), application specific integrated circuit (ASIC), or other component that executes a server-side haptic application  42  stored in a memory  44 . As later paragraphs will explain, though, the server-side haptic application  42  may operate in any processor-controlled device. 
     The server  20  receives a query  46  from the client device  22 . The client device  22  has a processor  48  (e.g., “μP”), application specific integrated circuit (ASIC), or other component that executes a client-side haptic application  50  stored in a memory  52 . The client-side haptic application  50  may cooperate with the server-side haptic application  42  to personalize haptic emulations of merchandise. When the client device  22  sends the query  46 , the query  46  may include a merchandise item number  54 . The merchandise item number  54  may be any data that uniquely identifies some merchandise. The user of the client device  22 , for example, usually selects some product or service from a shopping channel, an electronic catalog, or a website. If the user wishes to receive more information about the merchandise, the user&#39;s client device  22  sends the merchandise item number  54  to the server  20 . The server  20  queries a haptic database  56  for the haptic file  26  associated with the merchandise item number  54 . The server  20  then return sends the haptic file  26  to a network address associated with the client device  22  (or to any other destination address requested by the user). 
     Exemplary embodiments, though, may include an anatomical identifier  60 . Because the haptic file  26  may be personalized to the user&#39;s body dimensions, the server  20  may also return the anatomical identifier  60 . The anatomical identifier  60  may be included within the haptic data  28  of the haptic file  26 , and/or the anatomical identifier  60  may be separately sent. Regardless, the anatomical identifier  60  identifies some anatomical part that is associated with the merchandise item number  54 . For example, if the merchandise item number  54  identifies a bracelet, then the anatomical identifier  60  may identify “wrist.” Exemplary embodiments may then use the anatomical identifier  60  to custom-fit the haptic scan of the bracelet to the physical dimensions of the user&#39;s wrist. If the merchandise item number  54  identifies a jacket, then the anatomical identifier  60  may identify “chest,” “arm,” and/or “torso.” If the merchandise item number  54  identifies a “glove,” then the anatomical identifier  60  may identify “hand.” If the merchandise item number  54  identifies “pants,” then the anatomical identifier  60  may identify “leg.” Just as merchandise may be generally associated with different genres or categories of products and services, exemplary embodiments may associate the merchandise to different parts of the body. Exemplary embodiments may thus use the anatomical identifier  60  to personalize haptic emulations of merchandise. 
     As  FIG. 2  illustrates, the haptic database  56  may associate different merchandise item numbers  54  to different anatomical identifiers  60 . The haptic database  56  is illustrated as a table  62  that maps, relates, or otherwise associates the merchandise item number (or “MIN”)  54  to the corresponding haptic file  26 . Here, though, the haptic database  56  also associates the merchandise item number  54  to the corresponding anatomical identifier  60 .  FIG. 2  illustrates simple term associations, such as “wrist,” “hand,” and “head.” In actual practice, though, the anatomical identifiers  60  will likely be more complex alphanumeric combinations for detailed human or animal body parts. An index finger, for example, may be differentiated from a ring finger, a thumb, and a smallest fifth (“pinkie”) finger. The right hand may differentiated from the left hand, along with the corresponding digits. Differentiations may be applied to the feet, arms, legs, ears, and eyes. Other unique anatomical identifiers  60  may be associated to the torso, head, waist, chest, back, and other body parts or regions. Internal organs may also be identified, and the unique anatomical identifiers  60  may be applied to human and non-human species. One or more anatomical identifiers  60  may be assigned to multiple body parts, such as a combination finger-hand-wrist-forearm-elbow. 
     The server  20  responds to the query  46 . Whatever the anatomical identifier(s)  60 , the server-side haptic application  42  retrieves the one or more anatomical identifiers  60  that are associated with the merchandise item number  54 . The server  20  sends a query response  64 , such as the haptic file  26  and/or the one or more anatomical identifiers  60 . The query response  64  routes through the communications network (illustrated as reference numeral  24  in  FIG. 1 ) to the address associated with the client device  22 . 
       FIG. 3  illustrates personalization of haptic emulations. When the client device  22  receives the anatomical identifier  60 , the client-side haptic application  50  may query a profile database  70 . The profile database  70  is illustrated as being locally stored in the memory  52  of the client device  22 , but the profile database  70  may be remotely stored and accessed from any location in the communications network  24 . The profile database  70  stores the user&#39;s personalized anthropometrical data  32 .  FIG. 3  illustrates the profile database  70  as a table  72  that maps, relates, or otherwise associates different anatomical identifiers  60  to the corresponding anthropometrical data  32  of the user&#39;s body parts. If the anatomical identifier  60  is associated to a “wrist,” for example, then the client-side haptic application  50  retrieves the anthropometrical data  32  describing the user&#39;s wrist. If the anatomical identifier  60  identifies “arm,” then the anthropometrical data  32  for the user&#39;s arm is retrieved. The client device  22  then instructs the haptic emulator unit  30  to render the haptic data  28  to the user&#39;s anthropometrical data  32 . The haptic emulator unit  30  thus produces a haptic emulation of the merchandise associated with the merchandise item number  54 , but the haptic emulation is sized to the user&#39;s anthropometrical data  32 . Exemplary embodiments may thus use the anatomical identifier  60  to personalize haptic emulations of merchandise to the user&#39;s personal dimensions. The client-side haptic application  50  may even cause or instruct the processor  48  to produce a graphical user interface  74  on a display device  76 , thus allowing the user to further configure and personalize the haptic emulation (as later paragraphs will explain). 
     The profile database  70  may store profiles for multiple users. The profile database  70  may store a profile for each of multiple users, and each user&#39;s respective profile stores the user&#39;s personalized anthropometrical data  32 . Each user may thus establish their own personalizations for haptic emulations. Because the anthropometrical data  32  may describe body dimensions, health factors, and other sensitive information, any authentication and/or security procedures may be required to successfully access the user&#39;s personalized anthropometrical data  32 . 
       FIGS. 4-5  are schematics illustrating image modification, according to exemplary embodiments. Here exemplary embodiments may personalize images  80  of merchandise. When the server  20  receives the merchandise item number  54  from the client device  22 , the server  20  may also return one or more digital images  80  of the corresponding merchandise. The client device  22  may then modify the images  80  to include the user&#39;s personal body parts. 
     As  FIG. 4  illustrates, the haptic database  56  may associate the different merchandise item numbers  54  to the images  80  of the corresponding merchandise. The haptic database  56  may store pointers to one or more digital images or even video of the merchandise associated with the merchandise item number  54 . The server-side haptic application  42  retrieves the images  80  associated with the merchandise item number  54 . The server  20  may send the images  80  in response to the query  46 , perhaps along with the haptic file  26  and/or the anatomical identifier(s)  60 . When the client device  22  receives the images  80 , the client-side haptic application  50  may then personalize the images  80 . 
     As  FIG. 5  illustrates, the client device  22  may then consult the profile database  70 . The client-side haptic application  50  queries the profile database  70  for the user&#39;s personalized anthropometrical data  32  that is associated with the anatomical identifier  60 . The client-side haptic application  50  may then call or invoke an image modification module  82 . The image modification module  82  is a subset or routine of instructions or code that cause the client-side haptic application  50  to modify the one or more images  80 . The client-side haptic application  50  retrieves the personalized anthropometrical data  32  that is associated with the anatomical identifier  60 . The image modification module  82  then generates one or more modified images  84  using the anthropometrical data  32 . The modified images  84  may then be output to the display device  76  for display to the user. 
     The personalized anthropometrical data  32 , for example, may include personal anatomical images  90 . Each personal anatomical image  90  may be some digital image or dimensional data describing a body part of the user. The client-side haptic application  50  may then call or invoke the image modification module  82  to modify the image(s)  80  received from the server  20 . The image modification module  82  generates the modified image  84  using the personal anatomical image  90  of the user. The image modification module  82 , for example, replaces generic legs, arms, and/or hands with images and/or data representing the user&#39;s own legs, arms, and/or hands. The merchandise shown in the image  80  is thus modified to appear as being worn by the user. Any body part or feature in any image  80  may be personalized by substitution, replacement, overlay, deletion, addition, merger, or any other imaging technique. 
     Image modification drives purchases. As shoppers view merchandise for sale, exemplary embodiments may replace generic or impersonal features with personalized features. A model&#39;s hand, for example, may be replaced with the user&#39;s personal image of their hand. An image of a watch on a model&#39;s wrist may be modified to display the watch on the user&#39;s wrist. A hat or wig may be display on the user&#39;s head. Graceful, perfect hosts wearing the merchandise may be replaced with the user&#39;s personalized anthropometrical data  32 , thus yielding a far more persuasive selling environment. If the user&#39;s personalized anthropometrical data  32  includes a full-body, three-dimensional scan, then the user may see images and even video rendered using their own virtual avatar. 
       FIG. 6  is a schematic integrating both haptic emulation and image modification, according to exemplary embodiments. Here exemplary embodiments may use the personalized anthropometrical data  32  to persuasively combine haptic emulation and image modification. The haptic emulator unit  30  uses the haptic data  28  and the user&#39;s personalized anthropometrical data  32  to emulate the customized “touch-feel effect” of merchandise, per the user&#39;s physical dimensions. Simultaneously the client device  22  visually emulates how the merchandise would look on the user&#39;s body. If the user wishes to experience a jacket, for example, the haptic emulator unit  30  custom fits the jacket to the user&#39;s physical dimensions, while the display device  76  emulates how the jacket would look on the user&#39;s virtual body. Generic or model images of body parts may thus be visually replaced with the user&#39;s anthropometrical data  32 . 
     Exemplary embodiments may be applied to any emulator technology. The haptic emulator unit  30  generically provides some kind of force feedback to provide tactile and/or kinesthetic sensation(s). This feedback is used to provide perception of textures, ridges, vibrations, pulses, and even sounds and color. The haptic emulator unit  30  may use any technology, such as electro-mechanical actuation, ultrasound localized vibrators, micro-electric fields, viscous magnetic fluids, holographic projection, and/or organic light emitting diodes. The specific technology, though, is unimportant, as exemplary embodiments may be used to personalize any haptic emulation. Exemplary embodiments thus include the haptic emulator unit  30  having an ability to render customized haptic/tactile responses based on the anthropometrical data  32 . Current haptic emulators may be adapted to adjust haptic responses per user data residing outside of the haptic emulator unit  30 . For example, exemplary embodiments may modify the downloaded haptic file  26  per user data and supply it to a conventional haptic emulator unit. 
     Exemplary embodiments may include multiple types of haptic devices. For example, a glove-like device for appraising ornaments worn over hands (rings, bracelets, watches, bangles as well as gloves) and a neck-strap type device for necklaces. An abstract haptic scan of the merchandise may be combined with the personalized anthropometrical data  32 , visually and haptically/tactually, to simulate the user&#39;s experience. As each haptic emulator unit  30  may be expensive, multiple haptic emulators may not be practical. Exemplary embodiments thus envision that malls/arcades would have kiosks equipped with haptic emulators and haptic scanners. 
     A customer, for example, may visit a haptic kiosk in a local shopping mall. The customer selects a necklace in a catalog, and haptic scans and associated images of the necklace are downloaded to develop a composite haptic-visual representation. The customer supplies his or her personalized anthropometrical data  32  for personalizing the haptic emulation. The personalized anthropometrical data  32 , for example, may be stored in a memory card, USB device, or wireless memory device that the customer carries. Alternately, the customer&#39;s personalized anthropometrical data  32  may be downloaded from a website or remote computer. Regardless, the haptic emulating device at the kiosk will take as input the customer&#39;s personalized anthropometrical data  32  (or applicable portion of it) for the emulation. The customer perhaps dons a wearable haptic emulator unit, such as neck-strap-like device inside the kiosk to emulate haptic sensing of wearing the necklace. Similarly, the touch-feel of wearing a virtual pair of jeans may be emulated by a wearable haptic emulator unit in the shape of a pair of pants. The sensors embedded in the pants auto adjust per user measurements to supply haptic sensation. 
     Exemplary embodiments may also be applied to holographic simulation. Perhaps holographic simulation is an alternate solution to a multitude of haptic devices. Mall kiosks equipped with holographic simulation equipment may provide haptic rendering without any contraptions for body parts. A customer, for example, invokes haptic rendering in the mall kiosk and a hologram of the necklace appears around the customer&#39;s neck, which can be observed via a display device or a mirror. Exemplary embodiments may thus be applied to any holographic technology. 
     Haptic devices may be configured to suit any objective. For example, many bricks-and-mortar retailers (such as MACY&#39;S®) have a large area filled with several or even dozens of mattresses. Customers may lie on different mattresses and evaluate their comfort. Exemplary embodiments, though, allow the many different mattresses to be replaced by one or a few space-saving haptic emulator units  30 . Each haptic emulator unit  30  is preferably the same length and width as an actual bed, thus emulating the feel of each mattress as the customer evaluates. The customer&#39;s personalized anthropometrical data  32  is obtained, including the customer&#39;s weight distribution and body contours. The customer&#39;s personalized anthropometrical data  32 , for example, may be stored in a credit card-sized memory device for easy retrieval. The card&#39;s magnetic strip is swiped to obtain the customer&#39;s personalized anthropometrical data  32 . Regardless, the haptic emulator unit  30  may then realistically simulate the look and feel of each different mattress, thus relieving the retailer of large floor space. 
     Exemplary embodiments, likewise, may personalize any merchandise. Just as the haptic emulator unit  30  may personalize mattresses, the haptic emulator unit  30  may similarly personalize chairs and sofas. Automotive seats may be personalized to riders, and baby seats may be personalized to infants and toddlers. Ballistic vests may be personalized to each law enforcement officer and to each soldier. Indeed, exemplary embodiments may personalize any merchandise. 
       FIGS. 7-8  are schematics illustrating video implementation, according to exemplary embodiments.  FIG. 7  illustrates that exemplary embodiments may be applied to broadcast, cable, Internet Protocol, and any other video or television offering. Here the client device  22  receives a stream  100  of video data. The client device  22  may tune to a channel (e.g., a shopping channel) sent from a headend, request data from a content server, download a file, or any other request mechanism. For simplicity,  FIG. 7  illustrates the stream  100  of video data originating from a video server  102 . Regardless, when the user sees some merchandise for which haptic emulation is desired, the user selects the merchandise described or shown in the stream  100  of video data. The client device  22  then sends the query  46  to the server  20  with the merchandise item number  54 . The server-side haptic application  42  receives the merchandise item number  54 , queries the haptic database  56 , and retrieves the corresponding haptic file  26 . The server  20  sends the haptic file  26  and/or the anatomical identifier  60  to the client device  22 . The client device  22  retrieves the user&#39;s personalized anthropometrical data  32 , as earlier paragraphs explained. The haptic emulator unit  30  then renders the haptic file  26  using the user&#39;s personalized anthropometrical data  32 , also as earlier paragraphs explained. Moreover, exemplary embodiments may also personalize the stream  100  of video data with the user&#39;s personalized anthropometrical data  32 . Any video data in the stream  100  of video data may be modified to include the personalized anthropometrical data  32 . Suppose, for example, the user&#39;s personalized anthropometrical data  32  describes a virtual, but personal, avatar. Exemplary embodiments may thus personalize the video data in the stream  100  of video data. Again, graceful models and gushing hosts may be replaced with full-motion video generated using the user&#39;s personalized anthropometrical data  32 . This “lean-back” television approach to shopping is more effective for persuasive selling, thus driving sales and also improving customer satisfaction. 
       FIG. 8  illustrates time-delayed personalization. Here the client device  22  is illustrated as a digital video recorder (“DVR”)  110  that receives the stream  100  of video data. Here, though, the stream  100  of video data may also include the anatomical identifier  60 . When image modification is desired, the client-side haptic application  50  (such as the image modification module  82  illustrated in  FIGS. 5-6 ) causes the digital video recorder  110  to record a segment  112  of video data. The segment  112  of video data, for example, may be any portion of the stream  100  of video data for which image modification is desired. The personalized anthropometrical data  32  is retrieved that is associated with the anatomical identifier  60 . The client-side haptic application  50  then generates a modified segment  114  of video data using the anthropometrical data  32 . The modified segment  114  of video data may then output to the display device  76 . The image modification module  82  thus personalizes the segment  112  of video data by modifying video aspects or features with the user&#39;s personal images and/or dimensions. Because the personalization may require additional processing time, the modified segment  114  of video data may be delayed, perhaps by a second or more. The client-side haptic application  50  may cause the digital video recorder  110  to cache unmodified portions of the originally-received stream  100  of video data. The client-side haptic application  50  may also synchronize the modified segment  114  of video data with the unmodified portions of the originally-received stream  100  of video data, such that seamless time-delayed personalization is performed. 
     As  FIGS. 7-8  illustrate, exemplary embodiments include electronic shopping. Shopping channels (such as HSN® and QVC®) often present merchandise in a persuasive manner using graceful models and gushing hosts. Most consumers watch while relaxing in a comfortable couch or chair. This relaxed, “lean-back” shopping environment contrasts with Internet-based “lean-forward” web surfing through a catalogue or webpage for a single item. As such, “lean-back” television is more effective for persuasive selling than browsing through a web catalog. Exemplary embodiments thus enrich interactive audio-visual shopping experiences with personalized haptic rendering. The “lean-forward” verses “lean-back” difference (in Internet shopping verses TV shopping) maps into a more complicated back-end architecture for digital television. On the free Internet, quality of service and privacy are not guaranteed. Digital television, though, is enabled via private networks with tightly controlled quality of service and strict privacy. Exemplary embodiments thus personalize merchandise shown in advertisements, shopping channels, and programs. 
     Exemplary embodiments thus describe the Internet-based haptic database  56 . The haptic database  56  may be interconnected to IPTV-based shopping channels. The merchandise may be pre-scanned to obtain the haptic data  28  in each haptic file  26 . The haptic file  26  may thus be retrieved and routed to the client device  22 , such as a subscriber&#39;s set-top box, converter, television, computer, or mobile device (as later paragraphs will explain). Indeed, as tablet devices continue to evolve and to drop in price, exemplary embodiments encompass a tablet device with haptic emulation. 
     Exemplary embodiments personalize haptic emulations. A haptic/tactile scan, by itself, is abstract and non-personal. However, exemplary embodiments combine the haptic data  28  with the personalized anthropometrical data  32 . The personalized anthropometrical data  32  describes a user&#39;s, customer&#39;s, and/or subscriber&#39;s two- or three-dimensional measurements (perhaps obtained via 2D/3D scanning). Haptic emulations may thus be tailored to fit each person&#39;s unique physical features. For example, television and Internet via IPTV technology may be integrated. By leveraging Internet connectivity to pre-defined haptic-scan databases, IPTV consumers will be able to add haptic/tactile perception to audio-visual reception. Customers wanting to get a “touch-feel” before purchasing merchandise may do so from the home. The haptic emulator unit  30  thus emulates the customized “touch and feel” of merchandise while simultaneously the audio-visual medium (TV) emulates how the merchandise would look on the user&#39;s body. In the case of digital TV, the hand of the model showcasing the merchandise may be visually replaced by the user&#39;s avatar&#39;s hand, which is constructed based on the user&#39;s personalized anthropometrical data  32 . 
     In another example, a simple search for “brown corduroy” may yield the haptic emulation of the fabric suitable just for touch-feel. But exemplary embodiments personalize the haptic emulation, such that the same search combined with the user&#39;s personalized anthropometrical data  32  renders the emulation of a pair of customized brown corduroy pants made to fit, thus enriching the user&#39;s experience. 
     The haptic emulator unit  30 , however, may be too expensive for wide-spread adoption in homes. As earlier paragraphs mentioned, sophisticated emulator units may be installed in shopping malls, thus allowing mall shoppers to experience the benefits of haptic technology. Exemplary embodiments, though, include subscriber rental of the haptic emulator unit  30 . Because the haptic emulator unit  30  may be sophisticated, complicated, and perhaps expensive equipment, many users may prefer to rent the haptic emulator unit  30 . That is, the haptic emulator unit  30  may be rented from an Internet Service Provider or other entity, such as a cable, satellite, or DSL provider. The haptic emulator unit  30  may even be offered by individual merchants (such as AMAZON®) and by shopping channels. 
       FIG. 9  is a schematic further illustrating image modification, according to exemplary embodiments. Here the user may select body parts when illustrating merchandise. As  FIG. 9  illustrates, the client device  22  again sends the merchandise item number  54  to the server  20 , and the server  20  returns the haptic file  26 , the digital image(s)  80  of the corresponding merchandise, and/or the corresponding anatomical identifier  60 . Before or while rendering the haptic file  26 , the user may select how the image  80  of the merchandise is illustrated and/or emulated. The client-side haptic application  50  may cause the client device  22  to retrieve a menu  120  of the personal anatomical images  90 . As earlier paragraphs explained, each personal anatomical image  90  contains image data and/or dimensional data of the user&#39;s own body parts, such as arms, legs, hands, and torso. The client-side haptic application  50  may query the profile database  70  and retrieve a name of some or all personal anatomical images  90  in the user&#39;s profile. The menu  120  of personal anatomical images is visually displayed on the display device  76  and presents a listing  122  of the personal anatomical images  90 . The user graphically makes a selection  124  of a desired body part, such as by moving a cursor and selecting a graphical control or link. The client-side haptic application  50  may then call or invoke the image modification module  82  to generate the modified image  84  of the merchandise using the user&#39;s selected body part. An image of a watch, for example, may be generated on the user&#39;s wrist. A shirt may be sized and displayed on the user&#39;s own torso. The user may select and swap different body parts, such that the watch is alternately displayed on the user&#39;s wrist, the user&#39;s arm, and in the user&#39;s hand. Exemplary embodiments may personalize by substitution, replacement, overlay, deletion, addition, merger, or any other imaging technique. 
       FIG. 10  is a schematic further illustrating the personalized anthropometrical data  32 , according to exemplary embodiments. Here the profile database  70  may store the user&#39;s preferences  130  when emulating the haptic file  26  and/or when modifying the image  80  received from the server  20 . The user&#39;s preferences  130 , for example, may describe preferred cloth types, preferred textures, and/or preferred roughness/smoothness of fabrics and other materials. If the haptic file  26  does not specify mandatory haptic requirements, the client-side haptic application  50  may present the user with options to select various haptic finishes for merchandise. 
     As  FIG. 10  also illustrates, the profile database  70  may store the user&#39;s physiological data  132  and/or psychological data  134 . The profile database  70 , for example, may store the user&#39;s historical and/or current blood pressure, heart rate, and other vital signs. The user&#39;s personality traits may also be quantified and stored, perhaps describing the user&#39;s temperament, demeanor, and aggressiveness. These traits may be useful for accurate haptic rendering, especially during online interactive gaming. 
       FIG. 11  is a schematic illustrating a haptic search engine  140 , according to exemplary embodiments. Here the server-side haptic application  42  may act as a search engine to retrieve haptic search results. Unlike conventional text-based and image-based search engines, the haptic search engine  140  uses the haptic file  26  of an object as a primary input. The object is haptically scanned to obtain the haptic data  28  contained within the haptic file  26 . As  FIG. 11  illustrates, the haptic emulator unit  30  may have scanning capabilities to haptically scan objects of interest. Suppose, for example, a user wishes to search online for a fabric matching the “look and feel” of the upholstery of her couch. The user scans the upholstery (image+texture+touch-feel properties) using the scanning capabilities of the haptic emulator unit  30 . The haptic emulator unit  30  thus creates the haptic-scanned data file  26 . The haptic file  26  is then sent to the server  20 . Because the server-side haptic application  42  may act as a query handler, the server-side haptic application  42  accepts the haptic file  26  as an input. However, auxiliary inputs may also include video clips, photos, and text strings as metadata describing the object. The server-side haptic application  42  queries the haptic database  56  for other haptic files matching the query. The server-side haptic application  42  retrieves a search result  142  and sends the search result  142  to some destination (such as the client device  22 ). The search result  142  may even be sent or routed to the haptic emulator unit  30  for personalized haptic emulation (as earlier paragraphs explained). The shopper appraises the haptic emulation and decides to place the order, whereby the client-side haptic application  50  connects to an ordering and billing system to complete the order. As conventional ordering and billing methods are known, ordering and billing are not shown for simplicity. 
     The haptic search engine  140  may have a front end user interface. The haptic search engine  140  may accept composite inputs such that the search criteria may consist of haptic scan data along with regular text (ASCII) and photo/video (JPEG/MPEG) of any object. The haptic database  56  stores entries, and any entry may have multiple associated components. An entry in the haptic database  56 , for example, may include haptic scan data (tactile texture scan for 2D+physical properties such as rigidity, elasticity), image or multiple images in the case of a 3D body, a holographic scan of an item, and/or a 2D/3D/laser/optical scan of the item (physical size determination). This one-to-many relations in the haptic database  56  may include modifications to the data retrieval process of the haptic search engine  140  as well. With a conventional text-based search, a URL may be returned in response to a search query. In the haptic search engine  140 , though, a single query may return the multiple components described above. The client-side haptic application  50  is configured to accept this composite output, process it, and render the haptic emulation, integrated with audio-visual simulation, personalized/customized per individual user. 
     Exemplary embodiments may also extract specific haptic features. As those of ordinary skill may realize, haptic-scanned data files may be inherently large as they may contain 3D data. Conventional video-based search processes are burdened by the complexity of comparing video clips frame by frame multiple times, within a large data repository. This complexity hampers the usability of search engines designed for audio/video clip search. Exemplary embodiments may circumvent this complexity, while facilitating haptic searches, by extracting salient features of a haptic scan and casting the extracted data into a parameterized form (e.g., number of ridges per inch). Exemplary embodiments may, for simplicity, assume that a uniform surface (such as a fabric) has a repeating pattern and can be characterized by a minimal set of unique properties. In such a case the metadata (the data that describes actual data), would be sufficient to describe the object rather than a bulky file with full haptic scan data. 
       FIG. 12  is another schematic illustrating the haptic search engine  140 , according to exemplary embodiments. Here, though, the server-side haptic application  42  may query based on image data. As the user shops, the user sees some merchandise of interest (e.g., handbag, leather seat, wood table, clothing). The user downloads an image  150  of the merchandise from an online catalog or webpage. If the user sees the merchandise in a merchant&#39;s physical store, the user may instead capture the image  150  using a digital camera, smart phone, or other client device  22 . Regardless, the user submits the digital image  150  to the haptic search engine  140 . The user may also submit metadata, such as textual descriptions of the merchandise, the seller, merchant, and or catalog publication. The server-side haptic application  42  queries the haptic database  56  for the search results  142  matching the query. For example, the search results  142  may include the haptic file  26  matching the query. The server-side haptic application  42  retrieves the haptic file  26  and sends the haptic file  26  to the client device  22  (or any other requested destination). The haptic file  26  may then be sent or routed to the haptic emulator unit  30  to emulate the personalized haptic/tactile feeling. Simultaneously, the client-side haptic application  50  may also personalized images of the merchandise, as earlier paragraphs explained. The shopper appraises the personalized haptic emulation, and/or the personalized images, and decides to place an order. The client-side haptic application  50  connects to an ordering and billing system to complete the order (not shown for simplicity). 
       FIG. 13  is a flowchart illustrating haptic emulation, according to exemplary embodiments. As the user browses websites or watches Internet Protocol television, the user selects some merchandise of interest (Block  200 ). If the user desires the “touch and feel” of the merchandise, the user requests a haptic emulation (Block  202 ). The user, for example, may select a button on a remote control or select a graphical control in a graphical user interface. The client-side haptic application  50  obtains the merchandise item number  54  (Block  204 ). The client-side haptic application  50 , for example, may establish a connection to an Internet Protocol television data stream (such as the stream  100  of video data) to obtain the merchandise item number  54  and/or channel number from the Internet Protocol television data stream. The merchandise item number  54  may also be downloaded from an online catalog, website, or database. Regardless, the client-side haptic application  50  queries the server  20  for the merchandise item number  54  and/or the channel number (Block  206 ). The server-side haptic application  42  queries the haptic database  56  (Block  208 ) and returns the haptic file  26 , the image  80 , and/or anatomical identifier  60  (Block  210 ). The client-side haptic application  50  queries the profile database  70  for the anatomical identifier  60  (Block  212 ) and retrieves the personalized anthropometrical data  32  (Block  214 ). The haptic emulation is personalized (Block  216 ). If the user wishes to purchase the merchandise, the client-side haptic application  50  connects to a merchandise ordering and billing system to complete an order (Block  218 ). 
       FIG. 14  is a flowchart illustrating haptic emulation in electronic commerce, according to exemplary embodiments. Here the user may select the merchandise from an online catalog (Block  300 ). The client-side haptic application  50  queries to retrieve the merchandise item number  54  (Block  302 ). The client-side haptic application  50  queries the server  20  for the merchandise item number  54  (Block  304 ). The server-side haptic application  42  queries the haptic database  56  and retrieves the haptic file  26 , the image(s)  80 , and/or anatomical identifier  60  (Block  306 ). The client-side haptic application  50  queries the profile database  70  for the anatomical identifier  60  (Block  308 ) and retrieves the personalized anthropometrical data  32  (Block  310 ). The haptic emulation is personalized (Block  314 ). Again, if the merchandise is a bracelet, different individuals&#39; hands have different sizes and contours. Hence, the haptic experience is different for each individual, even though the merchandise is the same. If the haptic emulator unit  30  merely downloads the haptic file  26  and presents it to the user, the emulation will be generic. Exemplary embodiments thus use the personalized anthropometrical data  32  as additional inputs to the haptic emulator unit  30 . Utilizing the physical size and topography of the user&#39;s hand, the haptic emulator unit  30  will be able to accurately render a customized haptic feeling. In parallel, the personalized anthropometrical data  32  are used in creating a personalized visualization of the merchandise that is displayed (Block  316 ). The user, in other words, is shown wearing or experiencing the merchandise (e.g., the user is shown wearing the bracelet). The client-side haptic application  50  may synchronize the visual and haptic images (Block  318 ) such that when the user&#39;s hand is moved the touch feeling will vary accordingly. If the user wishes to purchase the merchandise, the client-side haptic application  50  connects to a merchandise ordering and billing system to complete an order (Block  320 ). 
       FIG. 15  is a flowchart illustrating haptic emulation in gaming environments, according to exemplary embodiments. Here the personalized anthropometrical data  32  may be applied to virtual environments. As the reader likely understands, virtual reality is a computer-simulated environment where users create avatars to represent themselves and to interact with other participants. The number of participants may be few or many (as in massively multiplier online games or “MMOGs”). Exemplary embodiments may personalize haptic emulations in virtual environments, and when players engage over the communications network  24  (such as the Internet). Even though avatars may be conventionally configured (such as for battle games), the virtual weaponry and costumes still need to fit the actual physical dimensions of the user pretending to wear them via haptic emulation. So the personalized anthropometrical data  32  is used for accurate rendering. 
     The user logs in and enters the virtual environment (Block  400 ). The user dons wearable haptic emulator units, such as weapons, armor, and costumes (Block  402 ). The user, for example, may wear haptic devices either at home environment or in a mall arcade equipped with such devices. The client device  22  calls or activates the client-side haptic application  50  and connects to the virtual environment, the haptic emulator units, the user&#39;s audio-visual environment, and the profile database  70  (Block  404 ). The client-side haptic application  50  may perform any authentication with the virtual environment to ensure the personalized anthropometrical data  32  is safely transmitted (Block  406 ). The user transacts with the virtual environment (Block  408 ). The user, for example, may virtually travel within the environment, obtain points or credits, and purchase or obtain dress paraphernalia and accoutrement for the user&#39;s avatar. The client-side haptic application  50  supplies the personalized anthropometrical data  32  to the virtual environment (Block  410 ), so that the goods/services can be customized per the user. During the virtual experience end users use the personalized goods and services supplied per their profiles. 
       FIG. 16  is a schematic illustrating user-generated haptic scans, according to exemplary embodiments. Here the user may scan objects and upload the resulting haptic file  26  to the haptic database  56 . Many users may wish to offer objects for sale on EBAY®, AMAZON®, CRAIG&#39;S LIST®, and other online websites. Exemplary embodiments thus permit users to haptically scan an object and offer the resulting haptic file  26  to potential buyers. As  FIG. 16  illustrates, here the haptic emulator unit  30  may also have a haptic/tactile sensor unit  500 . The haptic/tactile sensor unit  500  scans the object to obtain the haptic data  28 . The haptic data  28  is saved in the haptic file  26  and uploaded to the haptic database  56 . The haptic database  56  may then be queried for the haptic file  26 , as this disclosure explained. Again, the haptic/tactile sensor unit  500  may be purchased or rented and coupled to the IPTV-Internet environment via the client-side haptic application  50 . The availability of tactile touch-feel (in addition to a photo) would be an attractive feature for prospective buyers. 
       FIG. 17  is a schematic illustrating still more exemplary embodiments.  FIG. 17  is a generic block diagram illustrating the server-side haptic application  42  and the client-side haptic application  50  operating within a processor-controlled device  600 . As this disclosure explained, the server  20  and the client device  22  may operate in any processor-controlled device  600 .  FIG. 17 , then, illustrates the server-side haptic application  42  and the client-side haptic application  50  stored in a memory subsystem of the processor-controlled device  600 . One or more processors communicate with the memory subsystem and execute the server-side haptic application  42  and/or the client-side haptic application  50 . Because the processor-controlled device  600  is well-known to those of ordinary skill in the art, no detailed explanation is needed. 
       FIG. 18  depicts other possible operating environments for additional aspects of the exemplary embodiments.  FIG. 18  illustrates the server-side haptic application  42  and the client-side haptic application  50  operating within various processor-controlled devices  600 .  FIG. 18 , for example, illustrates that the server-side haptic application  42  and/or the client-side haptic application  50  may entirely or partially operate within a remote control  602 , a set-top box (“STB”) ( 604 ), the personal/digital video recorder (PVR/DVR)  110 , a personal digital assistant (PDA)  608 , a Global Positioning System (GPS) device  610 , an interactive television  612 , an Internet Protocol (IP) phone  414 , a pager  616 , a cellular/satellite/smart phone  618 , or any computer system, communications device, or processor-controlled device utilizing a digital signal processor (DP/DSP)  620 . The device  600  may also include watches, radios, vehicle electronics, clocks, printers, gateways, mobile/implantable medical devices, and other apparatuses and systems. Because the architecture and operating principles of the various devices  600  are well known, the hardware and software componentry of the various devices  600  are not further shown and described. 
     Exemplary embodiments may be physically embodied on or in a computer-readable storage medium. This computer-readable medium may include CD-ROM, DVD, tape, cassette, floppy disk, memory card, and large-capacity disks. This computer-readable medium, or media, could be distributed to end-subscribers, licensees, and assignees. These types of computer-readable media, and other types not mention here but considered within the scope of the exemplary embodiments. A computer program product comprises processor-executable instructions for personalizing haptic emulations, as the above paragraphs explained. 
     While the exemplary embodiments have been described with respect to various features, aspects, and embodiments, those skilled and unskilled in the art will recognize the exemplary embodiments are not so limited. Other variations, modifications, and alternative embodiments may be made without departing from the spirit and scope of the exemplary embodiments.
