PRIORITY CLAIM 
     This application claims the priority to the U.S. Provisional Application Ser. No. 60/842,626, entitled “Finger Mounted Mobile Computer,” filed Sep. 5, 2006. The specification of the above-identified application is incorporated herewith by reference. 
    
    
     FIELD OF THE INVENTION 
     The present invention relates generally to a mobile device that is wearable in a plurality of locations. 
     BACKGROUND 
     Circuit technology has advanced to allow mobile devices to incorporate small hardware components, thereby also decreasing the size of the mobile device itself. Mobile device technology has also advanced to allow portability. For example, conventional mobile devices may be equipped with wearable mechanisms to increase the flexibility of the user while still utilizing the functions of the mobile device. These wearable mechanisms may be used to hold the conventional mobile device on a variety of locations. However, the mobile device may be limited to a particular location to be worn. Thus, the mobile device may be efficient to perform certain functionalities when worn in a particular location but inefficient to perform other functionalities when worn in that particular location. 
     Conventional mobile devices may further equip other hardware devices such as scanners, RFID readers, etc. However, these other hardware devices are wired externally into the conventional mobile devices. Thus, the functionality of the mobile device and/or other hardware devices may be interrupted when, for example, the wiring is disconnected. Conventional mobile devices may integrate the other hardware devices. However, these devices must be hand-held in order to use, for example, a scanner.

     DETAILED DESCRIPTION 
     The present invention may be further understood with reference to the following description and the appended drawings, wherein like elements are referred to with the same reference numerals. The exemplary embodiments of the present invention describe a mountable mobile computer that may be worn in a variety of locations using a variety of mounts. For example, the mountable mobile computer may be worn on a finger, a wrist, and a waist. The mounts may include a fastening device to securely fasten the mountable mobile computer to the finger, wrist, or waist. Therefore, according to the exemplary embodiments of the present invention, depending on the location in which the mountable mobile computer is worn, various functionalities may take precedence over other functionalities. The mountable mobile computer, various mounts, and respective functionalities will be discussed in detail below. 
       FIG. 1  shows an exemplary embodiment of a mountable mobile computer  100  according to the present invention. The mountable mobile computer  100  may be a mobile terminal that may be worn on various locations of a user&#39;s body when combined with a respective mount. The mountable mobile computer  100  may include various components and functions. In  FIG. 1 , the mountable mobile computer  100  may include a top housing  105 , a bottom housing  110 , a display  115 , a scanner  120 , an audio output  125 , and a voice input  126 . The mountable mobile computer  100  may include further components and functionalities beyond what is illustrated in  FIG. 1 . These further components and functionalities will be discussed in more detail below with reference to  FIG. 2 . In addition, the mountable mobile computer  100  may include a keypad (not shown) to enable a user to manually input data, switch between menus or displays on the display  115 , activate/deactivate components, etc. The keypad may be several pin buttons found along a side of the housing  105 , buttons found on a top side of the housing  105 , etc. The key pad may also be embodied as part of the display  115 . That is, the key pad may be a touch screen that is part of the display  115 . The mountable mobile computer  100  may also include a port (not shown) to enable a user to insert other hardware devices such as a removable memory device (e.g., a secure digital (SD) card). 
     The top housing  105  and the bottom housing  110  may provide a casing for the components of the mountable mobile computer  100 . In the exemplary embodiment, the components may be housed within the top housing  105  and the bottom housing  110  or at least partially on the periphery of the top housing  105 . For example, the display  115 , the scanner  120 , the audio output  125 , and the voice input  126  may be housed at least partially on the periphery of the top housing  105 . The further components may be housed within the top housing  105  and the bottom housing  110 , which will be discussed in more detail below. It should be noted that the display  115 , the scanner  120 , the audio output  125 , and the voice input  126  may be designed using conventional technologies but are sized to fit within/on the top and/or bottom housing  105 ,  110 . Due to the size of the mountable mobile computer  100 , the display  115  may be designed to show only relevant information corresponding to the intended uses of the mountable mobile computer  100 . The top housing  105  and the bottom housing  110  may be manufactured using a rigid plastic. The bottom housing  105  may exhibit a concave curvature that corresponds to a curvature of a respective body location. 
       FIG. 2  shows an exemplary interior view of the mountable mobile computer  100  of  FIG. 1 . As discussed above, the mountable mobile computer  100  may also include components within the top housing  105  and the bottom housing  110 . In the exemplary embodiment, within the top housing  105  and the bottom housing  110 , the mountable mobile computer  100  may include the scanner  120 , the audio output  125 , the voice input  126 , a processor  130 , a memory  135 , a network device  140 , a RFID (radio frequency identification) transceiver  145 , an antenna  150 , a battery  155 , and a charger  160 . It should be noted that the mountable mobile computer  100  may include further components not shown in the exemplary embodiment. It should again also be noted that the components found within the mountable mobile computer  100  are manufactured using conventional technologies but are sized to fit within the housing  105 . 
     In the exemplary embodiment, the scanner  120 , the audio output  125 , and the voice input  126  may also be at least partially on the periphery of the housing  105  and within the housing  105 . The scanner  120  may include circuitry (e.g., scanning engine) that is housed within the housing  105  to protect it from any potential damage. However, the scanner  120  may also include a capturing device (e.g., camera) that requires a line of sight to an object it scans. For example, the scanner  120  may be a bar code scanner or an imager that reads an object. Therefore, a portion of the scanner  120  may be found on the periphery of the housing  105 . The audio output  125  and the voice input  126  may also include circuitry that may be housed within the top housing  105  and the bottom housing  110  to protect it from any potential damage. The audio output  125  may be a speaker and the voice input  126  may be a microphone. Therefore, including the audio output  125  and the voice input  126  on the periphery of the housing  105  may improve any sound qualities since the sound waves are not required to pass through a barrier (e.g., walls of the housing  105 ). However, it should be noted that the audio output  125  and the voice input may be found completely within the top housing  105  and the bottom housing  110  since, unlike the scanner  120 , the audio output  125  and the voice input  126  do not require a direct path for incoming and outgoing sound waves. 
     The processor  130  may be a central computing unit of the mountable mobile computer  100 . The processor  130  may be responsible for management of the components of the mountable mobile computer  100 . As illustrated in the exemplary embodiment, the scanner  120 , the audio output  125 , the voice input  126 , the memory  135 , the network device  140 , the RFID transceiver  145 , the battery  155 , and the charger  160  may be electrically connected to the processor  130 . 
     The memory  135  may be a storage unit of the mountable mobile computer  100 . The processor  130  may access the memory  135  to retrieve or send data. The memory  135  may include both a read-only memory (ROM) that includes preset data that is intended to be used by the finer mounted mobile computer  100  and random-access memory (RAM) that includes data that is inputted and retrieved by the processor  130 . 
     The network device  140  may be a connection unit of the mountable mobile computer  100 . The network device  140  may enable the mountable mobile computer  100  to access a network that is available in an area where the mountable mobile computer  100  is located. In the exemplary embodiment, the network device  140  may wirelessly connect to an available network. However, it should be noted that the network device  140  may connect through physical means (e.g., cables, wires, etc.). In such an embodiment, the network device may include a port (not shown) that is located on the housing  105  to receive a network access cable. The network device  140  may also provide wireless connections such as IEEE 802.11, 802.16, Bluetooth, etc. It should be noted that the mountable mobile computer  100  includes the proper components to allow it to be used as, for example, a cellular phone. Thus, the network device  140  may be used in such a capacity. Due to the size of the mountable mobile computer  100  and the nature of telephone use, a separate antenna may be incorporated to be used with, for example, a wireless headset. However, it is noted that the mountable mobile computer  100  may already include the necessary components to provide telephonic capabilities. 
     The RFID transceiver  145  and the antenna  150  may be units that read RFID tags (i.e., transponders). The RFID transceiver  145  may receive/transmit RFIDs via the antenna  150  from available RFID tags. The RFID tags may be located on various objects. For example, in a warehouse environment, the RFID tag may be on a package. Thus, when a user wearing the mountable mobile computer  100  approaches (passive) or scans (active) the RFID tag with the RFID transceiver  145  via the antenna  150 , the RFID may be read and may be, for example, processed by the processor  130  and subsequently stored in the memory  135 , sent to the network via the network device  140 , etc. 
     The battery  155  may be a unit that provides the power to the mountable mobile computer  100 . In the exemplary embodiment, the battery  155  may be, for example, a coin battery. The housing  105  may include a panel (not shown) that allows a user to remove/replace the battery  155 . The battery  155  may also be a rechargeable (i.e., lithium ion) battery. The housing  105  may include a port that receives a recharging unit that recharges the battery  105 . The mountable mobile device  100  may be equipped with the charger  160  so that the battery  155  is not required to be removed or replaced when the capacity of the battery  155  has been fully discharged. For example, the mountable mobile device  100  may be placed in a cradle so that electrical contacts (not shown) may couple to corresponding contacts on the cradle to recharge the battery  155  via the charger  160 . 
       FIG. 3  shows an exemplary finger mount  200  used in conjunction with the mountable mobile computer  100  of  FIG. 1 . It should be noted that the finger mount  200  may be a part of the mountable mobile computer  100  and not a separate unit. For example, the mountable mobile computer  100  may include straps with fasteners that may affix the mountable mobile computer  100  on a user&#39;s finger. The fasteners may be, for example, hook and loop fasteners, snaps, buttons, etc. The mountable mobile computer  100  may also utilize a ring or spring clip to affix the mountable mobile computer  100  on the user&#39;s finger. The mount  200  may be manufactured using the same materials used to manufacture the housing  105 . 
     In the exemplary embodiment, the finger mount  200  may attach to the mountable mobile computer  100  on the bottom housing  110 . A mechanical connector (not shown) on the mountable mobile computer  100  may be used to attach the finger mount  200  to the mountable mobile computer  100 . The connector may be, for example, a male connector shaped as a ring with tabs adapted for insertion into a corresponding connector on the finger mount  200 . The tabs may provide a locking mechanism via recesses or cut-outs that prevent movement of the mountable mobile computer  100  with respect to the finger mount  200 . The connector may also provide for rotation, allowing the user to orient the mountable mobile computer  100  as desired. 
     The finger mount  200  may be designed to affix the mountable mobile computer  100  on any of the user&#39;s fingers. For example, the mountable mobile computer  100  may be mounted on a proximal or distal portion of the user&#39;s finger. In the exemplary embodiment, the mountable mobile computer  100  may be mounted on the index finger. However, it should be noted that the mountable mobile computer  100  may be mounted on a user&#39;s middle, ring, pinky, or thumb finger of either a left or right hand, depending on the user&#39;s preference. Additionally, the mount  200  may be mounted on multiple adjacent fingers, for example, the index and middle fingers. 
     In the exemplary embodiment, the finger mount  200  may include straps  210  equipped with fasteners. The fasteners may be, for example, hook and loop fasteners, snaps, buttons, etc. Those skilled in the art will understand that the straps  210  with fasteners allow the finger mount  200  to adjust to accommodate a user&#39;s finger. A bottom side  205  of the finger mount  200  may also exhibit a concave curvature that conforms to a curvature of the user&#39;s finger to provide comfort for the user. 
     As discussed above, the straps  210  may be replaced with a spring clip. The spring clip (not shown) may adjust its width to accommodate the user&#39;s preference for the location on a specific finger. For example, the spring clip may hold an original position that is narrow. Once a user inserts a finger, the spring clip may expand to correspond to the width of the finger. Also, as discussed above, the straps  210  may also be replaced with a ring. The ring may be manufactured using an expandable material (e.g., flexible plastic, rubber, etc.) to accommodate the user&#39;s preference for the location on a specific finger. The ring may also be manufactured using a rigid material (e.g., rigid plastic, metal) that is custom designed for an individual user&#39;s location on a specific finger. 
     It should be noted that the straps  210  or any other holding mechanism may be designed with two holding sites. That is, one set of straps may be disposed toward a distal end of a finger and another set of straps may be disposed toward a proximal end of a finger. The use of two holding sites may provide a stabilization of the mountable mobile computer  100 . Furthermore, the mountable mobile computer may be larger than the mount, in particular, a width of the straps  210  or other holding mechanism. That is, the mountable mobile computer  100  may extend beyond the mount  200 . A stabilizing holding mechanism may alleviate any inadvertent movement as a consequence of using the mountable mobile computer  100 . 
     The finger mount  200  may also include a scanning trigger  215 . As discussed above, a user may actively scan or read RFID tags. To accommodate an active scanning process, the scanning trigger  215  may be provided. The trigger  215  may comprise any type of mechanical and/or electrical switch. For example, the trigger  215  may be a push button, a rocker switch, a slide switch, a pressure sensitive switch, etc. In the exemplary embodiment, the trigger  215  may be a mechanical push button encased within a flexible membrane (e.g., a rubber cover). The trigger  215  may be communicatively coupled to the mountable mobile computer  100 . The trigger  215  may communicate with the mountable mobile computer  100  via an electrical coupling. Thus, the trigger  215  may be engaged by depressing the flexible membrane that activates the scanner  120 , thereby enabling a scanning of a barcode or another function. In an exemplary embodiment, when the trigger  215  is engaged, a mechanical and/or electrical connection between the mount  200  and the mountable mobile computer  100  may be established. 
     It should be noted that the finger mount  200  may include other components such as electrical components. For example, the finger mount  200  may include a memory, a micro-processor, a communication and power contacts, and a battery. The finger mount memory may function and perform substantially similar to the memory  135 . The finger mount memory may store data pertaining to the finger mount  200  and/or the mountable mobile computer  100 . The micro-processor may function and perform substantially similar to the processor  130  except the micro-processor pertains to the finger mount  200 . The finger mount communication and power contacts may provide an electrical connection to corresponding contacts pertaining to communication and power capabilities. The finger mount battery may provide a power supply to the finger mount  200  but may also provide a power supply to the mountable mobile computer  100  via the power contacts. 
       FIG. 4  shows an assembled view of the finger mount  200  of  FIG. 3  attached to the mountable mobile computer  100  of  FIG. 1 . As discussed above, in the assembled view, the finger mount  200  may be attached to the mountable mobile computer  100  on the bottom housing  110 . The finger mount  200  may be attached toward a front side (toward the scanner  120 ) of the bottom housing  110  of the mountable mobile computer  100 . However, it should be noted that the finger mount  200  may be attached along any portion of the bottom housing  110 . In this exemplary embodiment, the assembled view shows that the length of the finger mount  200  does not surpass the length of the mountable mobile computer  100 . Because the mountable mobile computer  100  is designed to be worn on a user&#39;s finger when attached to the finger mount  200 , the length of the finger mount  200 , the mountable mobile computer  100 , and/or the assembled unit may exhibit a length of a proximal phalanx of the user&#39;s finger. This may enable a user to freely bend the finger to which the mountable mobile computer  100  is mounted, further providing flexibility for the user. Furthermore, the orientation of the finger mount  200  having a longitudinal axis parallel to a longitudinal axis of the mountable mobile computer  100  is only exemplary. That is, the finger mount  200  may be oriented so that the longitudinal axis is perpendicular to the longitudinal axis of the mountable mobile computer  100 . 
     In another exemplary embodiment, the mountable mobile computer  100  may be assembled with the finger mount  200  so that when in an operative position, the holding mechanism (e.g., straps  210 ) of the finger mount  200  is placed on a distal end of a finger. Furthermore, the mountable mobile computer  100  may be large and extend beyond the width of the finger mount  200 . In such an embodiment, the mountable mobile computer  100  may extend onto the back of the hand of a user. Thus, when a user uses the mountable mobile computer  100 , the back of the hand serves as a steadying surface (e.g., provides an opposing force) when, for example, the user pushes keys/buttons. This exemplary embodiment would not require a stabilizing holding mechanism (e.g., two sets of straps) as discussed above. It should be noted that the mountable mobile computer  100  may be oriented on an inner surface of a finger and the mountable mobile computer  100  may extend toward a wrist onto the palm of the hand of the user. 
       FIG. 5  shows an exemplary wrist mount  300  to be used in conjunction with the mountable mobile computer  100  of  FIG. 1 . It should be noted that the wrist mount  300  may be a part of the mountable mobile computer  100  and not a separate unit. For example, the mountable mobile computer  100  may include straps with fasteners that affix the mountable mobile computer  100  on a user&#39;s wrist. The fasteners may be, for example, hook and loop fasteners, snaps, buttons, etc. The mountable mobile computer  100  may also utilize a spring clip to affix the mountable mobile computer  100  on the user&#39;s wrist. The wrist mount  300  may be manufactured using the same materials used to manufacture the housing  105 . Furthermore, due to a larger possible discrepancy between a wrist of a first user and a wrist of a second user, the wrist mount  300  may be elastic to suit the various circumferences of wrists. 
     In the exemplary embodiment, the mountable mobile computer  100  may be incorporated into the wrist mount  300 . An electrical connector may be disposed to electrically couple the mountable mobile computer  100  with the wrist mount  300 . However, it should be noted that the wrist mount  300  may also simply house the mountable mobile computer  100 . 
     The wrist mount  300  may include a recess  305 , a data input arrangement  310 , and straps  315 . The recess  305  may be used as a location in which the mountable mobile computer  100  is housed in the wrist mount  300 . The recess  305  may allow a user to insert the mountable mobile computer  100 . Various locking mechanisms may be included with the recess  305  to securely fasten the mountable mobile computer  100  with the wrist mount  300 . For example, retractable blocks may extend into the recess  305 . While the mountable mobile computer  100  is being inserted, the blocks may retract. Once the mountable mobile computer  100  has been fully inserted, the blocks may return to an extended state into corresponding recesses on the mountable mobile computer  100 . The recess  305  may extend the entire length of the wrist mount  300 . The wrist mount  300  may also include other electrical components as described above with reference to the finger mount  200 . 
     The wrist mount  300  may include a data input arrangement  310 . As discussed above, the mountable mobile computer  100  may be designed to be relatively small. Accordingly, a data input arrangement disposed on the mountable mobile computer  100  may also be relatively small. To provide convenience for the user, the data input arrangement  310  may provide larger keys, larger key prints, etc. Furthermore, the data input arrangement  310  may provide further data inputs for the user to enter. That is, when the mountable mobile computer is worn on the wrist, various functionalities may require the user to enter parameters or other data. However, it should be noted that the wrist mount  300  may not include the data input arrangement  310 . That is, another embodiment of the wrist mount  300  may include only the recess  305  and the straps  315 . 
     The wrist mount  300  may include the straps  315 . The straps  315  may be attached to the sides of the wrist mount  300 . The straps  315  may be the mechanism that holds the wrist mount  300  to a user&#39;s wrist. The straps  315  may be elastic, thereby allowing the wrist mount to be held taut to various sizes of wrists. The straps  315  may include connectors  320  that fasten the straps  315  together around the user&#39;s wrist. The connectors  320  may be any fastening mechanism such as hook and loop fasteners, snaps, buttons, etc. 
     Similar to the finger mount  200 , the straps  315  may be replaced with a spring clip. The spring clip (not shown) may adjust its width to accommodate the user&#39;s preference for the location on the wrist. For example, the spring clip may be placed toward the hand side of the wrist. A user may slide the wrist mount  300  toward the elbow side of the wrist, thereby increasing the diameter of the spring clip and keeping the wrist mount  300  in a taut position. The spring clip may be manufactured using a flexible polymer. The straps  315  may also be replaced with an adjustable belt. The adjustable belt may increase in diameter to allow a user to slide a hand therethrough. Once the adjustable belt is around the wrist, the user may pull the belt to decrease the diameter, thereby conforming to the diameter of the wrist. 
     Also similar to the finger mount  200 , the straps  315  or any other holding mechanism may be designed with two holding sites. That is, one set of straps may be disposed toward a distal end of the wrist and another set of straps may be disposed toward a proximal end of the wrist. The use of two holding sites provides a stabilization of the mountable mobile computer  100 . Because a wrist tapers toward the distal end, the proximal holding mechanism may have a larger diameter than a distal holding mechanism. 
     A bottom side of the wrist mount  300  may exhibit a concave curvature that conforms to a curvature of a user&#39;s wrist. In contrast to a rounder finger, the curvature of the wrist mount  300  may be less steep than the curvature exhibited by the finger mount  200 . Furthermore, the curvature of the wrist mount  300  may be adjustable to conform to any size of a user&#39;s wrist. The curvature of the wrist mount  300  may cover half a surface area of the wrist. By covering at least half a surface area of the wrist, the wrist mount  300  may be stable on the user&#39;s wrist, thereby allowing, for example, the user to comfortably push keys on the data input arrangement  310 . It should be noted that the concave curvature is only exemplary and the wrist mount  300  may have a linear bottom side with no curvature. 
       FIG. 6  shows an assembled view of the mountable mobile computer  100  of  FIG. 1  attached to the wrist mount  300  of  FIG. 5 . As discussed above, in the assembled view, the mountable mobile computer  100  may be incorporated into the wrist mount  300 . The mountable mobile computer  100  may attach to the wrist mount  300  via the recess  305 . However, it should be noted that the mountable mobile computer  100  may be inserted into the wrist mount  300  if the recess  305  is accessible via a hole. The hole may be disposed on a longitudinal side of the wrist mount  300 . When the mountable mobile computer  100  is attached to the wrist mount  300 , the mountable mobile computer  100  is designed to be worn on a user&#39;s wrist. Consequently, the length of the wrist mount  300 , the mountable mobile computer  100 , and/or the assembled unit may be up to a length of a forearm of a user. The wrist mount  300  also allows ambidextrous use of the mountable mobile computer  100 . That is, the wrist mount  300  may be worn on either a left or right wrist and the mountable mobile computer  100  may be inserted accordingly. 
       FIG. 7   a  shows a front side of an exemplary waist mount  400  to be used in conjunction with the mountable mobile computer  100  of  FIG. 1 . It should be noted that the waist mount  400  may be a part of the mountable mobile computer  100  and not a separate unit. For example, the mountable mobile computer  100  may include straps or clips that affix the mountable mobile computer  100  on a user&#39;s waist. The straps may circumscribe the user&#39;s waist while the clips may attach to a belt or other edge found on a user&#39;s waist. The waist mount  400  may be manufactured using the same materials used to manufacture the housing  105 . 
     In the exemplary embodiment, the mountable mobile computer  100  may be incorporated into the waist mount  400 . An electrical connector may be disposed to electrically couple the mountable mobile computer  100  with the waist mount  400 . However, it should be noted that the waist mount  400  may also simply house the mountable mobile computer  100 . 
     The waist mount  400  may include a recess  405 . The recess  405  may be used as a location in which the mountable mobile computer  100  is housed. The recess  405  may substantially resemble the recess  305  of the wrist mount  300 . For example, the recess  405  may also include various locking mechanisms to securely fasten the mountable mobile computer  100  with the waist mount  400 . As illustrated, the recess  405  may provide a user to insert the mountable mobile computer  100  into a hole that leads to the recess  405 . However, the recess  405  may allow a user to directly insert the mountable mobile computer  100  therein. 
       FIG. 7   b  shows a back side of the exemplary waist mount  400  of  FIG. 7   a . The waist mount  400  may include a belt clip  410  to attach the mountable mobile computer  100  to a user&#39;s waist. The belt clip  410  may be spring loaded to retract to an original position once clipped to a belt, pants seam, etc. It should be noted that the belt clip  410  may be used to clip the waist mount  400  in other locations as well, for example, a bag strap. That is, the waist mount  400  may be used to attach the mountable mobile computer in any location where the belt clip  410  may be used. The waist mount  400  may also include other electrical components as described above with reference to the finger mount  200 . 
       FIG. 8  shows an assembled view of the mountable mobile computer  100  of  FIG. 1  attached to the waist mount  400  of  FIG. 7   a . As discussed above, in the assembled view, the mountable mobile computer  100  may be incorporated into the waist mount  400 . The mountable mobile computer  100  may attach to the waist mount  300  by inserting the mountable mobile computer  100  through a hole into the recess  405 . However, it should be noted that the mountable mobile computer  100  may be directly inserted into the recess  405 . 
     As discussed above, the exemplary embodiments of the present invention utilize a worn position as a means to determine precedence of functionalities of the mountable mobile computer  100 . For example, when the mountable mobile computer  100  is attached to the finger mount  200  and worn on a user&#39;s finger, functionalities such as scanning and RFID capabilities may take precedence to functionalities such as voice capabilities. In another example, when the mountable mobile computer  100  is attached to the wrist mount  300  and worn on a user&#39;s wrist, functionalities such as RFID capabilities may take precedence over functionalities such as scanning and voice capabilities. In yet another example, when the mountable mobile computer  100  is attached to the waist mount  400  and worn on a user&#39;s waist, functionalities such as voice capabilities may take precedence over functionalities such as scanning and RFID capabilities. It should be noted that the term “precedence” may refer to either an enabling/disabling of functionalities, an ordering of a list in which certain functionalities are given priority over other functionalities (e.g., allocate more resources to one functionality over another), or a combination thereof. 
     The position in which the mountable mobile computer  100  is worn may determine other factors. For example, the display  115  may include a touch pad data input arrangement. Thus, depending on the worn position, the display  115  may show different types of touch pad configurations. That is, various user interface configurations may be determined based on worn location. For example, when the mountable mobile computer  100  is worn on a finger, a touch pad focusing on keys pertaining to scanning and RFID capabilities may be displayed. In another example, when the mountable mobile computer  100  is worn on a wrist, a touch pad focusing on keys pertaining to RFID capabilities only may be displayed. In yet another example, when the mountable mobile computer  100  is worn on a waist, a touch pad focusing on voice capabilities such as a telephone pad may be displayed. 
     The mountable mobile computer  100  may include a mechanism to determine a relative position in which the mountable mobile computer  100  is being worn. Through this determination, the processor  130  may properly determine the precedence of functionalities. The following description describes an exemplary mechanism in which the mountable mobile computer determines the precedence of functionalities. 
       FIG. 9   a  shows an exemplary contact  505  for the finger mount  200  of  FIG. 2 . The contact  505  may be a coupler disposed on any surface of the finger mount  200 . However, it should be noted that the contact  505  may be required to be positioned on a surface that contacts the mounted mobile computer  100  when assembled. The contact  505  may be, for example, a pin. The pin may be metallic and therefore serve as an electrical coupler between the finger mount  200  and the mounted mobile computer  100 . The contact  505  may be a flat pin that is flush with the surface in which it is disposed. The contact  505  may provide a signal that is transmitted upon a completed circuit. 
       FIG. 9   b  shows an exemplary contact  510  for the wrist mount  300  of  FIG. 5 .  FIG. 9   c  shows an exemplary contact  515  for the waist mount  400  of  FIG. 7   a . The contacts  510 ,  515  may be substantially similar to the contact  505  of the finger mount  505 . According to the exemplary embodiment, the contacts  505 ,  510 ,  515  may be located at a predetermined site. The differing locations may provide the necessary difference for the mounted mobile computer to determine the worn location. For example, the contact  505  may be disposed at a high location; the contact  510  may be disposed at a low location; and the contact  515  may be disposed at a central location. It should be noted that the use of location as the indicator is only exemplary. The present invention may utilize other forms of indicating to the mounted mobile computer  100  the worn location. These forms will be discussed below. 
       FIG. 9   d  shows exemplary contacts  520  for the mountable mobile computer  100  of  FIG. 1 . The contacts  520  may be corresponding contacts where one of the contacts  520  couples to one of the contacts  505 ,  510 ,  515  of the various mounts. For example, a top contact of the contacts  520  may correspond to the contact  505  of the finger mount  200 ; a bottom contact of the contacts  520  may correspond to the contact  510  of the wrist mount  300 ; and a middle contact of the contacts  520  may correspond to the contact  515  of the waist mount  400 . Thus, when the mountable mobile computer  100  determines which of the contacts  520  is coupled, a determination may be made as to the types of functionalities to give precedence. As discussed above, the contacts  505 ,  510 ,  515  may be pins. Thus, the contacts  520  may be corresponding pin holes. If the contacts  505 ,  510 ,  515  are flat pins, a coupling with the contacts  520  may complete the circuit and a location signal may be received by the mountable mobile computer  100 . 
     Other mechanisms of determining worn location may be embodied by the present invention. For example, the contact  520  may be a single pin hole while the contacts  505 ,  510 ,  515  may be a pin at a common location with varying lengths. Thus, when any of the contacts  505 ,  510 ,  515  is inserted into the contact  520 , a sensor or electrical connection may be established allowing the processor  130  to determine the worn location. In another example, contacts may not be used. If the mount is capable of transmitting a signal to the mountable mobile computer  100 , a worn location may be ascertained. In yet another example, the locking mechanisms that secure the mounted mobile computer  100  to the respective mount may be used as the location determination mechanism. The different mounts may secure the mounted mobile computer  100  in different areas of the housings  105 ,  110 . Thus, when certain corresponding locks or set of locks of the mounted mobile computer  100  are engaged, a determination may be made. 
     The exemplary embodiment of the mountable mobile computer  100  described above present several advantages over a conventional wearable terminal. For example, the mountable mobile computer  100  is designed for ambidextrous. Therefore, regardless of user preference, every user may be accommodated. Those skilled in the art will understand that the finger mount  200  may be attached to any substantially cylindrical shape (e.g., a finger) and does not discriminate between fingers on a right hand or a left hand. The same applies to the wrist mount  300 . As discussed above, the waist mount  400  may be worn in any site in which the belt clip  405  may be used. In addition, those skilled in the art will understand that a detachable mount allows the mountable mobile computer  100  to be worn so that, for example, the display  115  is always in a correct orientation with respect to the user. 
     Another advantage is the versatility and efficiency provided by the different locations the mountable mobile computer  100  may be worn. For example, the mountable mobile computer  100  may be worn in different locations depending on an application in which the user performs. The user may efficiently utilize the mountable mobile computer  100  because the worn location does not hinder any use of the functionalities. Furthermore, additional components may be attached to the mountable mobile computer such as a headset (when worn on the waist). These additional components may be uncomfortable and detrimental to the user if the mountable mobile computer is worn at a particular location. 
     It will be apparent to those skilled in the art that various modifications may be made in the present invention, without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
