Visual 190 may also include text 190T, to be displayed on display 132, or to be sent to mobile device 150 and used for informational and/or social purposes, such as informing the user's friends of the visual currently exhibited by the user's ornament.
Basic Operation Involving a Server
FIG. 6 schematically describes the basic operation of a preferred embodiment of the present invention. In step 301, the identifier of the current skin attached to main unit 124 is identified, either by processor 130A of main unit 124 retrieving the skin identifier from the skin identifier 146A registered in skin chip 146, or by camera 164 of mobile device 150 taking a picture of the current skin. In the case of a picture, the taken skin image will be further processed, by either processor 152 of mobile device 150 or by processor 172 of server 170, to determine the skin identifier. In step 305, either the skin identifier or the taken picture is sent by mobile device 150 to server 170. In step 309, the server chooses one or more visuals 190 from server store 180 that match the skin identifier. The one or more visuals may be chosen according to a previously-prepared lookup table, that lists, for each skin identifier, matching visuals. The lookup table is possibly prepared according to topical and aesthetic considerations, by human observers that apply personal judgment, intuition and taste; building such a lookup table may also be performed or assisted by machine intelligence, using methods that extend beyond the scope of the present disclosure.
In step 313, mobile device 150 receives from server 170 the one or more visuals selected by the server in step 309. In case of more than one visual, step 317 diverts to step 321, which prompts the user to select the visual to be displayed. In step 325, the selected visual is provided by mobile device 150 to wearable ornament 120, which is then exhibited by step 329 on the display 132 of wearable ornament 120. In some embodiments, step 329 also includes playing an audio track 190A, that is part of the selected visual 190, on the speaker 158 of mobile device 150.
Basic Operation with an Autonomous Mobile Device
In some embodiments or instances, the selection and supply of visuals can be made autonomously by a mobile device, without involving a server.
FIG. 7 schematically describes an embodiment that involves only an ornament and a mobile device. Is step 331, the ID of the current skin attached to main unit 124 is identified, either by processor 130A of main unit 124 retrieving the skin identifier from the skin identifier 146A registered in skin chip 146, or by camera 164 of mobile device 150 taking a picture of the current skin. In the case of a picture, the taken skin image is further processed, by processor 152 of mobile device 150, to determine the skin identifier. In step 335, the mobile device chooses one or more visuals included in mobile device store 166, that match the skin identifier. The one or more skins may be chosen according to a previously-prepared lookup table, that lists, for each skin identifier, matching visuals. The lookup table is possibly prepared according to topical and aesthetic considerations, by human observers that apply personal judgment, intuition and taste; building such a lookup table may also be performed or assisted by machine intelligence, using methods that extend beyond the scope of the present disclosure. In case of more than one visual, step 339 diverts to step 343, which prompts the user to select the selected visual to be displayed. In step 347, the selected visual is provided by mobile device 150 to wearable ornament 120, which is then exhibited by step 351 on the display 132 of wearable ornament 120. In some embodiments, step 351 also includes playing an audio track, that is part of the selected visual, on the speaker 158 of mobile device 150.
Basic Operation with Skin-Resident Visuals
An ornament may have an operation mode where the displayed visual is retrieved from visuals memory 146B (FIG. 2N) of the currently-attached skin. Such visuals may be the only visuals associated with the skin, or may serve as default visuals, until the user decides to obtain an alternative matching visual from the mobile device 150 or server 170.
FIG. 8 starts in step 371, where a skin 140 is attached to main unit 124. Under the current scenario, skin 140 includes a skin chip 146, that further includes visuals memory 146B. Thus, in step 373, the main unit 124 connects with skin chip 146 via main unit connections 136 and skin connections 148, and in step 375, the main unit 124 retrieves from visuals memory 146B a visual, which is further exhibited, in step 379, on display 132.
It will be noted that, in the general case (see visual 190 of FIG. 4), a visual may include a still image, a video track and optionally also an audio track to be played on a mobile device, such an audio track will preferably be sent for playback from visuals memory 146B via wearable ornament 120 to mobile device 150. It will also be noted the visuals memory 146B of skin chip 146 may store a plurality of visuals, allowing the user to use his mobile device 150 for selecting one of the plurality of visuals for being exhibited on display 132.
Group Operation
Members of a group, such as a social group, a political party or fans of a certain celebrity, often wish to identify themselves with the group by exhibiting visuals, such as buttons, banners etc. In an embodiment of the present innovation, such members of a group acquire a skin related to the group, attach the skin to their main unit, and then automatically exhibit a group-related visual on their wearable ornament 120. In groups having a group leader, the group leader may use a group leader terminal in order to simultaneously update the visuals of all group members. It will be noted, that in the context of the present discussion, a “group member” is a user that has selected to attach the respective group skin to his or her main unit.
FIG. 5 schematically depicts a group system 200, used by a plurality of users 210A . . . 210N, each user having a respective wearable ornament 120A . . . 120N and a respective mobile device 150A . . . 150N. All mobile devices include a group skin having the same skin identifier, and, as a consequence, are assigned the same visual by server 170, which visual may be determined and intermittently updated by the group leader via leader terminal 220, which is any computing device that can be used by a group leader to communicate with server 170, such as a personal computer, or a mobile device. Thus, preferably, in the group scenario, at any moment there is single visual that is considered a match for the group skin, but this visual may be intermittently updated by the group leader via leader terminal 220. It will also be noted, that a visual 190 (FIG. 4) may include a still image 190S, a video track 190V, both for display on display 132, an audio track 190A, preferably for playback on speaker 158 of mobile device 150, in sync with the video playback on display 132 of wearable ornament 120, and optionally also text 190T, to be displayed on display 132, or to be sent to mobile device 150 and used for informational and/or social purposes, such as informing the user's friends of the visual currently exhibited by the user's ornament. It will be noted that often a group leader will wear one of the group wearable ornaments, and his or her wearable ornament will exhibit the same visual, that will change in sync with the other group members. It will also be noted, that a group may count just the leader and another member, such as in the case of a couple that likes the idea of having the same visual exhibited and changing simultaneously on their personal wearable ornaments.
FIG. 9 depicts a process of maintaining the visuals exhibited on ornaments 120A-N of FIG. 5. It is presumed that identical skins (the group skin) are to be attached to the main body of all ornaments of the group members, and FIG. 9 describes the process experienced by a representative ornament, that is any of the ornaments 120A-N. In step 401, leader terminal 220 is used by the leader of the group for entering a selected visual, or selecting a visual from a previously-entered collection of visuals; the selected visual (the current group visual) is entered or identified to the server 170, and is the visual that server 170 will match to the group skin identifier. In step 403, the group skin is attached, by the group member, to the main body of his or her ornament. In step 405 the group skin identifier is identified by the respective mobile device of the group member, similarly to step 301 of FIG. 6. In step 407, the group skin identifier is sent by the mobile device to server 170. In step 413, the mobile device receives from the server the current group visual, that currently matches the group skin identifier. If the current group visual has changed from the previous group visual, then in step 417 the current group visual is provided to the ornament for presentation, and in step 421 the current visual is actually presented. If video and audio tracks are included with the current visual, then the audio track is played by the mobile device in sync with the video track being exhibited on the display 132 of wearable ornament 120. Then, loop 411, continuously or intermittently, is used for rechecking the current group visual selected by the group leader, and for updating the visual exhibited on the ornament, upon the leader, via step 409, updating the current group visual.
Sometimes it is desirable to accurately synchronize the visuals exhibited by the ornaments of the group members, for example, in a meeting of the group, and especially when the current group visual includes a sound track played by the respective mobile devices. Ideally, the process of FIG. 9 synchronizes the exhibition of content, since all the group ornaments respond to changes made centrally in step 409 by the group leader via leader terminal 220. However, in practice, both the delay caused by loop 411 and the latency of the ornament-mobile device and mobile-device-server communication, may cause noticeable difference between the exhibition of visuals by different ornaments within the same group.
FIG. 9A describes a process, that is similar to that of FIG. 9, but is adapted to accurately synchronize the exhibition of the current visual among the ornaments of the group. Steps 401-405 are as described above with reference to FIG. 9. In step 409A, the group leader terminal attaches to the next group visual also a timing, e.g. a specific hour, that is, for example, 30 seconds ahead of the current time, in a format such as 10:03:44. Then, in step 413A the mobile device receives the next group visual+timing from the server, and, in step 417A, the next group visual is temporarily stored in the visuals memory 130B. In the embodiment of FIG. 9A, it is presumed that mobile device 150 has an accurate real-time clock, while wearable ornament 120 has no such clock; accordingly, in step 419A it is the mobile device 150 that detects, via its real-time clock, that the specified timing (such as 10:03:44) is reached, and sends to wearable ornament 120 a short signal that means “UPDATE NOW”. In step 421A the “UPDATE NOW” signal is received and interpreted by wearable ornament 120, which causes the temporarily-stored next group visual to be exhibited and become the current group visual. The loop 411 is kept safely below the exemplary 30 seconds delay, for example repeated each 10 seconds, which ensures that all group ornaments will switch at once to exhibiting a new visual. It will be noted that if processor 130A of wearable ornament 120 includes an accurate real-time clock, then step 417A can send the next group visual and the timing to the ornament, step 419A can be dropped and step 421A is then triggered by the ornament's real-time clock reaching the visual switching timing.
Miscellaneous Operations and Features
FIG. 10 describes an optional mode of operation, wherein accelerometer 130C (FIG. 2M) of wearable ornament 120 is used, in step 451, to detect the rhythm of wearable ornament 120, which is presumed to be the same as the rhythm of the user who wears wearable ornament 120, such as when dancing, and if the rhythm is found consistent, then in step 455, the rhythm of the video exhibited by wearable ornament 120 is adapted to the rhythm of the wearable ornament 120. In some embodiments, the changing rhythm may be reported to mobile device 150, to affect automatic selection of a visual that matches the current rhythm according to a lookup table. In some embodiments, an accelerometer built into mobile device 150 (not shown) may undertake the roles of accelerometer 130C described above, under the assumption that the current motion of mobile device 150 is similar the current motion of wearable ornament 120.
FIG. 11 describes how accelerometer 130C can be applied for saving power. Presuming that if the wearable ornament 120 is kept at absolute rest for a predetermined period of time, say 5 minutes, then it can be presumed not to be worn, and can display a still version instead of a video version, or even having the display turned-off after another period of rest. For the following discussion, the current visual 190 is presumed to have both a still image 190S version and a video track 190V version (FIG. 4). Thus, in step 461, processor 130A interprets signals received from accelerometer 130C to detect motion. If no signals have been received for a predefined period of time, such as 5 minutes, then step 465 decides “AT REST” status, which branches to exhibiting in step 469S the still version of the current visual 190, with the goal of saving power. If motion is detected, then step 465 branches toward exhibiting the video version in step 469V. Step 461 remains further active, to switch from video to still and back, as needed.
FIG. 12 describes in more detail an alternative method for identifying the current skin 140 attached to main unit 124, as briefly introduced in step 301 of FIG. 6 and step 331 of FIG. 7. Three methods are covered by the three columns, while the rows represent actions taken in wearable ornament 120, mobile device 150 and server 170, respectively. A first method starts in step 501, where processor 130A of wearable ornament 120 retrieves from skin chip 146 of skin 140 its skin identifier 146A. In step 505 the skin identifier is received by mobile device 150 from wearable ornament 120, and in step 509 the skin identifier is received by server 170 from mobile device 150. According to a second method, in step 515, a picture of the skin is taken by camera 164 of mobile device 150, and image processing in combination with a skin image database hosted in the memory of mobile device 150 (not shown in FIG. 3) are used to retrieve the skin identifier from the skin picture. The skin identifier is then received, in step 519, by server 170 from mobile device 150. Under a third method, in step 525, a picture of the skin is taken by camera 164 of mobile device 150, and in step 529, the skin picture is received by server 170 from mobile device 150, where image processing and server store 180 are used to retrieve the skin identifier.
While the invention has been described with respect to a limited number of embodiments, it will be appreciated by persons skilled in the art that the present invention is not limited by what has been particularly shown and described herein. Rather the scope of the present invention includes both combinations and sub-combinations of the various features described herein, as well as variations and modifications which would occur to persons skilled in the art upon reading the specification and which are not in the prior art.
