Also, the terminology used herein is for the purpose of description and not of limitation.
[0054]Referring now to the Figures, in various exemplary embodiments, the technology described herein provides a system 10, components, and methods for viewing documents 16 or objects using a webcam 12. The system is small, lightweight, portable, and easy to mass manufacture with minimal moving parts. The system 10 is configured to be assembled very rapidly, typically in less than fifteen seconds.
[0055]A "webcam" 12 is a video camera connected to a computer 18 or other suitable device so that its output may be viewed, either directly on a display unit or transmitted over the Internet, cellular telephone, etc. Additionally, other types of picture and video capture devices, whether existing today or developed in the future, are suitably used as a component in the system 10 disclosed herein, as long as such picture or video capture device is capable of being repositionably attached to the support device 14 disclosed herein and is also capable of transmitting pictures or videos to display unit as defined elsewhere herein. To be suitable for use, the video or picture capture device, i.e., the webcam 12 (as the term is defined herein), has the ability to provide the picture or video in digital form (either directly or through conversion) to a display unit suitable for viewing the picture or video.
[0056]"Display unit" means the device upon which a viewer observes the video or pictures captured by the webcam 12 used in the system 10 of the technology described herein, such as for example, a laptop screen 20, LCD flat screen 22, or projector screen 26. The display unit can be, for example, a computer, digital projector 24, Smartphone, PDA, television, computer monitor, extended monitor, video projector, and the like, configured to accept a video or picture signal captured by the webcam 12 via a wired 28, e.g. USB, such as 48, or the like or a wireless connection.
[0057]In relation to the support device 14 used to support the webcam 12 during use, "repositionably attached" or "repositionably attachable" means that the webcam 12 can be attached and reattached to the support device 14 as needed and desired by the user.
[0058]"Remotely located viewer" means a viewer who views a video or picture captured by a webcam 12, where the picture or video is transmitted by signal to viewer in another location from the person conducting the meeting. When a remote viewer is attending a meeting, the signal from the webcam 12 is transmitted via the Internet or by device suitable to transmit a picture and/or video from the webcam. Examples of such suitable transmission devices can comprise, in non-limiting examples, a PDA e.g. I-Phone® or a Blackberry®, or a Smartphone.
[0059]In one aspect, the technology described herein comprises a system 10 for capturing video and/or pictures of documents, objects or the like using a webcam, as this term is defined elsewhere herein. In pertinent part, the system 10 comprises a support device 14, wherein the support device 14 allows repositionable attachment of the webcam 12 thereto. The system 10 can also comprise a display unit, such as screens 20, 22, 26 for example, capable of accepting videos and/or picture signals from the webcam.
[0060]A significant feature of the technology disclosed herein is that the system 10 allows anything placed within the visual frame of the webcam 12 to be transmitted either to an in-person audience or to a remote viewer substantially in real time and/or captured for later viewing.
[0061]In one aspect, the technology described herein can be used to facilitate in person meetings--that is, when a speaker is in the same room as the audience--by allowing a speaker to easily show documents, such as paper 16, or objects to an audience in real time. In such an aspect, the technology described herein provides a highly portable and flexible substitute for a traditional overhead projector system. Specifically, unlike traditional overhead projector systems, the system 10 of the technology described herein typically weighs less than about one pound and can be set up for use very quickly. Moreover, unlike traditional overhead projectors, the system 10 of the technology described herein allows video and pictures to be captured for later review.
[0062]In a particularly useful aspect of the technology described herein, writings or edits made by hand can be made to a document or permanent markings can be made to an object, where such writings, edits and markings can be viewed substantially in real time by the audience. The ability of a group to view such activities improves the ability of others to verify that the document or object is an authentic version thereof at a later time. As one example of this aspect, edits can be made to a contract to be viewed by a group in a meeting setting, and those changes can be verified later through review of a video capture of the edits. Still further, in an auction setting, an object can be marked such as by the auctioneer to demonstrate to a group that a buyer purchased that particular object. The buyer can later authenticate the identity of the object by comparing the marking made as shown in the video with the marking on the actual object. In yet a further example, Bible study can be conducted in a group setting to demonstrate to an audience the place in the Bible from which the study leader is reading. This can be recorded for later playback.
[0063]To operate in the facilitation of in person meetings, the videos and/or pictures captured from the webcam 12 that is repositionably attached to the support device 14 can be transmitted via wired 28 or wireless connection to, for example, a computer 18, PDA, Smartphone or digital projector 24 for viewing by the audience. The videos and/or pictures can be viewed in real time or can be recorded (or otherwise "time shifted") for playback at a later time.
[0064]The software used to transmit captured video or pictures from the webcam 12 repositionably mounted on the support device 14 to the display unit e.g. computer 18, PDA, Smartphone, television or digital projector 24, is not currently believed to be critical to the technology described herein. As such, when the webcam 12 is repositionably mounted on the support device 14 the software provided with the webcam 12 to allow capture or display of the captured pictures or video can suitably be used.
[0065]In a further aspect, the technology described herein facilitates meetings where at least two of the participants therewith are located in different locations. In this case a remote viewer is able to see a document or object in real time as that document or object is, for example, discussed, marked or edited by someone present therewith. The system 10 of the technology described herein is highly flexible and can be used to capture images for transmission to remote user or captured for later review such as, almost any document form and size, book, contract or notes. In a particularly useful aspect of the technology described herein, notations can be transmitted to a remote viewer in substantially real time or captured for later viewing.
[0066]In a pertinent example of this aspect of the system 10 of the technology described herein, edits to drawings can be captured by the webcam 12 and transmitted to a remote user in substantially real time or captured for later viewing. In a further pertinent example, brainstorming can occur between participants in different locations. The flexibility of the system 10 of the technology described herein allows such remotely located users to both take notation and directly communicate with the other participants.
[0067]To allow a remote viewer to observe a document or object while being discussed or described by a speaker in another location, standard peer-to-peer meeting software can be used to transmit the captured video or pictures. Such software includes branded products such as WebEx® (owned by Cisco Corporation), Go to Meeting® (owned by Citrix) and Skype®. When the system 10 is used for a remote meeting, software that allows a user to view split or dual screens can provide tremendous benefits because a presenter can show a document 16 or object while still maintaining a conversation with a viewer located away from the presenter. For example, the presenter can orient him or herself to one webcam 12 while at the same time capturing a picture or video with the webcam repositionably attached to the support device 14. As one example, a teacher can provide real time edits to a student's class assignments while the student watches from a remote location by using the webcam 12 repositionably attached to the support device 14 while at the same time the teacher is speaking directly to the student through a second webcam 12 positioned at eyelevel.
[0068]Still further, the system 10 of the technology described herein can be used to demonstrate aspects of an object to a remote viewer or captured for later viewing. For example, a remote viewer can be shown aspects of an object for purchase. As one example of this aspect, a merchant can show a remote purchaser a product using the system 10. For products having unique features, such as antiques, art, coins or the like, the seller can identify the object using some sort of security device while the purchaser is watching in real time, such as a seal or signature etc. When the purchaser receives the object, he can compare the security feature captured using the system 10 of the technology described herein with the security feature present on the product as received. This provides the purchaser with proof that the product received is the actual product requested from the remote seller.
[0069]In one aspect, the support device 14 permits repositionable attachment of a webcam 12 thereon, where the support device 14 and webcam 12 comprise a significant aspect of the system 10. Significantly, the support device 14 allows the webcam 12 to be repositionably attached so as to substantially prevent environmental sources of vibration from being transmitted to the webcam 12. It should be noted that many webcams 12 (as well as other modern video capture devices) include software that provides digital picture stabilization to reduce or eliminate shaking of the picture when viewed. The stabilization provided by the support device 14 of the system 10 of the technology described herein is distinguishable from such software-derived picture stabilization. In other words, the webcam 12 attached to the support device 14 of the technology described herein is isolated or substantially isolated from environmental sources of vibration due to the shape and composition of the support device 14 and the way the webcam 12 is attached to the support device 12. The technology described herein therefore allows stable viewing of a picture or video from a webcam 12 even if digital picture stabilization is absent or substantially absent from the webcam 12 or other picture or video capture device.
[0070]The support device 14 of the system 10 of the technology described herein can be prepared from metal, plastic or any other suitable material. Since the support device 14 is intended to easily transportable by a user, it can be desirable to prepare the support device 14 out of a lightweight material. If metal is used, the support device 14 can be suitably prepared out of aluminum or other lightweight metal. If plastic is used to prepare the support device 14, the plastic should be strong and rigid enough to support a webcam 12 thereon. Moreover, regardless of the material used to prepare the support device 14, the device should be fabricated so as to substantially prevent environmental sources of vibration from being transmitted from the surface upon which the support device 14 is mounted to the webcam 12. This feature of the support device 14 can significantly improve the functionality of the system because the webcam is effectively isolated from any vibration in the environment.
[0071]In one aspect, the support device 14 can comprise an approximately z-shaped (whether oriented correctly or in reverse) structure fabricated out of suitable material (as discussed elsewhere herein), wherein the structure comprises an upper projection 52 and a lower projection 50, wherein the upper and lower projections 52, 50 are each joined at one end to a stem 54. The upper and lower projections 52, 50 can be oriented as depicted in the Figures.
[0072]Moreover, the orientation of the upper and lower projections 52, 50 of the support device 14 in relation to each other and each to the stem 54 also comprises a notable aspect of some aspects of the technology described herein. The inventor has found that when the lower projection 50 is substantially flat against a substantially flat surface, a webcam 12 attached to the support device 14 having a stem 54 oriented at an approximate 45 degree angle to the lower projection 50 provides substantial flexibility in use. The upper and lower projections 52, 50 can each, independently, be oriented in a bent, offset or twisted orientation in relation to the stem 54. Specifically, the approximate 45 degree angle allows the webcam 12 to be moved along the stem 54 at substantially any location and still be oriented to allow the webcam 12 to be used to visualize both large and small documents and objects.
[0073]In a further aspect, the stem 54, and consequently the distance by which the upper and lower projections 52, 50 are separated, can be of any suitable length to allow capture of pictures or video using a webcam repositionably attached thereto. For example, when viewing large documents 16 (such as schematics or architectural drawings), a longer stem 54 can allow visualization of the entire document 16 in a single visual frame. Similarly, a shorter stem 54 can allow visualization of a smaller document in a single visual frame. If a longer stem 54 is used, a webcam 12 repositionably attached to the stem 54 can be virtually infinitely repositioned along the length of the stem 54 to allow pictures and videos of documents and objects of various sizes without separately adjusting the focus or orientation of the webcam 12. This allows the user to focus on his or her conversation or presentation with the remote viewer, rather than needing to repeatedly refocus the camera 12 to obtain a clearer or close-up picture.
[0074]Yet further, the support device 14 can be disassembled to improve the portability of the system 10 of the technology described herein. To this end, the stem 54 can be comprised of at least two separate parts, such as a lower stem 38 and an upper stem 40, that are connected by as fastener. Examples of suitable fasteners include, for example, a screw or a cotter pin 44 or the like. Pin 42 can be grasped by ring 46 and placed through pin hole 44 to secure the lower stem 38 and the upper stem 40 one to another. As such a telescoping effect is created, as shown, for example, by telescoping direction 36, as depicted specifically in FIG. 4. For storage and transport, the at least two parts 38, 40 of the stem 54 can be rotated on an axis (such as that resulting from a circular connector substantially permanently attaching the at least two parts) so that the at least two parts 38, 40 of the stem 54 substantially nest so as to reduce the overall length of the stem 54. For use, the at least two parts 38, 40 of the stem 54 can be rotated on the axis and fastened or locked to provide an assembled support device 14 comprising the at least two parts.
[0075]In a further method to permit disassembly the support device 14 to improve portability, a groove or pin hole 44 can be present in one or more of the at least two parts 38, 40 of the support device 14. One or more screws or other type of fastener 42 can be used to assemble the at least two parts 38, 40 of the support device 14. The support device 14 can be lengthened and shortened for use and portability by re-positioning the location of the fastener 42 as appropriate.
[0076]In a significant aspect, when the webcam 12 is repositionably attached to the support device 14, the user is able to rotate the webcam 12 substantially throughout a 360 degree orientation without dismounting the webcam 12 from the support device 14. Rotation can include, for example, rotation in direction 32, as depicted in FIG. 2. Similarly, rotation can include, for example, rotation in direction 34, as depicted in FIG. 3. Moreover, such rotation can occur substantially without distortion of the picture quality because the lower projection allows the webcam 12 to effectively glide smoothly along a substantially flat surface such as a table or lectern. The substantial non-distortion is accomplished as a result of the orientation of the support device 14 having the webcam 12 repositionably attached with the surface upon which the support device 14 is situated.
[0077]The webcam 12 can be repositionably attached to the support device 14 using one or more attachment methods. Repositionable attachment of the webcam 12 to the support device can be accomplished using a hook and eye system e.g. Velcro® wherein the hook part is securely attached to the stem and upper projection of the support device and the eye part is securely attached to the webcam (or vice versa). Additionally, the stem 54 and upper projection 52 of the support device 14 can be configured to allow the webcam 12 to be attached by inclusion of repositionable attachment directly onto the support device 14. For example, the webcam 12 can be configured with a magnetized aspect to allow repositionable attachment to the stem 54 and upper projection 52. Still further, the stem 54 and upper projection 52 can include grove functionality and the webcam 12 can include tongue functionality (or vice versa) so that the webcam 12 can be moved along the surface of the support device 14 to allow the webcam 12 to be repositionably attached thereto. Yet further, the upper projection 52 and stem 54 can be configured in any manner that allows the webcam 12 to be repositionably attached thereto.
[0078]The support device 14 (whether or not the stem 54 is comprised of one part or at least two parts) can comprise the repositionable attachment e.g., Velcro, along the entire length or along only a part of the length of the stem 54. For example, when the stem 54 comprises two parts rotatable on an axis, the repositionable attachment can be included substantially on one part of the stem 54. In such an aspect, the repositionable attachment may extend along a top side, a lower side or both of the upper projection 52 to permit the webcam 12 to be mounted thereon to provide enhanced viewing range in use.
[0079]In a further aspect, the support device 14 (whether or not the stem is comprised of one part or at least two parts) can include the repositionable attachment on an upper and lower side of the stem 54. For example, when the stem 54 comprises at two parts 38, 40, the upper part 40 of the stem 54 can include Velcro along its upper length and continuing to the top side of the upper projection 52. The Velcro can also be present on the bottom side of the lower projection 50 and, optionally, continuing down the bottom side (that is the side facing away from the other side) of the first part of the two part stem.
[0080]In use, the support device 14 having a webcam 12 repositionably attachable thereto is itself attached to a substantially flat surface, such as a table or lectern or other suitable surface, using a clamp 30 or any other suitable fastener. The method of fastening the support device 14 to a substantially flat surface is not currently believed to be significant to the operation of the technology described herein. However, in order to suitably isolate the webcam 12 from environmental vibration so as to provide a substantially distortion free picture or video, the support device 14 should be substantially rigidly fastenable to the substantially flat surface. In other words, loose fastening of the support device 14 to a table, lectern or other mounting surface will make it more likely that environmental sources of vibration will be transmitted to the webcam 12, which could decrease the quality of the picture or video obtained from the webcam 12.
[0081]Without being bound by theory, the inventor herein believes that the angle and orientation of the support device 14 effectively assist in dissipating environmental vibrations before such vibrations can reach the webcam 12. Accordingly, it is currently understood that the support device 14 allows the webcam 12 to capture videos and/or pictures without substantial distortion thereof, where such lack of distortion is substantially independent of any anti-distortion software associated either with the webcam 12 or an attendant display unit.
[0082]A further component of the system 10 of the technology described herein is a webcam 12 or other device that can capture or transmit pictures or video depictions of objects as defined elsewhere herein. While a webcam 12 today comprises a highly suitable device for use in the system 10, it is expected that other devices will be useable with the technology described herein. The device used to capture a picture or video of the object is not believed to be critical to the functionality of the technology, as long as the device can be suitably repositionably attached to the support device. When a webcam 12 is used, high resolution devices typically are beneficial. Webcam 12 technology is improving rapidly, as such it is expected the suitable webcams (as well as other devices) will change substantially in the not-too-distant future. However, at the present time, a highly suitable webcam 12 for use as a component in the system 10 is made by Logitech under the 9000 Pro brand.
[0083]If the webcam 12 comprises a wired connection to transmit the pictures or video, the support device 14 can be configured to allow suitable concealment or containment of the cord to assist in ease of use of the system 10. Such concealment or containment can be by clips or other type of fastener, or the support device 14 can comprise a way to allow the cord 28 to be integrated into the support device 14 itself The system 10 of the technology described herein shows particular utility wherever an overhead projector or digital projector can be used. Moreover, the system 10 can also be used to as a highly portable document scanner. Still further, the system 10 can be used to improve the quality of remote meetings. In such aspect, the person conducting the meeting can speak directly to the remote viewer using the one webcam 12 (such as the webcam 12 embedded within or attached to the computer 18) while using the system 10 to display documents or objects in a separate window. The system 10 therefore allows the feeling enhanced engagement of remote viewers with the person conducting the meeting and the information that is being discussed therein. Significantly, the improved meeting quality is possible at substantially less expense than currently available with telepresence technology existing today.
