DESCRIPTION OF THE ILLUSTRATIVE EMBODIMENTS

[0032] The present invention relates to holograph-projecting watch devices and methods therein. The principles and operation for providing such devices and methods, according to the present invention, may be better understood with reference to the accompanying description and the drawings.

[0033] Referring to the drawings, FIG. 1A depicts a side view of a holograph-projecting watch device, according to embodiments of the present invention. A watch is shown having a watch base 2 on which is mounted an opaque watch face 4 and a transparent watch cover 6. Opaque watch face 4 is rigidly attached to watch base 2. A light wand 8 is configured to be spun on a rotatable spinning axis 10, automatically driven by a motorized component (not shown) in watch base 2. In some embodiments, an optional spinner casing 12 is configured to rotate light wand 8, on spinning axis 10, above opaque watch face 4. In such embodiments, spinner casing 12 can be manually driven by a user spinning optional spinner casing 12, and/or automatically driven by a motorized component (not shown) in watch base 2.

[0034] In other embodiments, only light wand 8 rotates on spinning axis 10 (e.g., axle mounted in a bearing). A wand/face spacing 14 is shown indicating the spacing between light wand 8 and opaque watch face 4. In such embodiments, optional spinner casing 12 is a stationary casing with light wand 8 being automatically driven by a motorized component (not shown) in watch base 2. In both embodiments described, light wand 8 is configured to rotate freely on spinning axis 10. In motorized embodiments, such rotation is regulated. Light wand 8 includes a series of controllable light-emitting elements (e.g., LEDs) which can be configured to project holographic content.

[0035] A face/cover gap 16 is shown indicating the gap from opaque watch face 4 to transparent watch cover 6). While in principle face/cover gap 16 represents the total range of height positions for light wand 8 (i.e., wand/face spacing 14) within the constraints of allowing light wand 8 to rotate freely without contacting other parts of the watch housing (e.g., transparent watch cover 6), additional constraints are imposed for producing a suitable holographic projection as described below.

[0036] FIG. 1B depicts a side view of the holograph-projecting watch device of FIG. 1A with the wand/face gap maximized, according to embodiments of the present invention. Wand/face spacing 14 is shown maximized (i.e., the farthest suitable distance from opaque watch face 4 available) to raise light wand 8 above opaque watch face 4 as close as possible to transparent watch cover 6.

[0037] FIG. 2 depicts a side view of the holograph-projecting watch device of FIG. 1A with traditional watch hands below the light wand, according to embodiments of the present invention. A spinning axis 20 is shown adapted to accommodate light wand 8 as well as traditional watch hands 22 such as hour, minute, and second hands. A wand/face spacing 24 is shown adapted to raise light wand 8 above watch hands 22 in order to prevent interference of light wand 8 with the rotation of watch hands 22.

[0038] FIG. 3 depicts a side view of the holograph-projecting watch device of FIG. 1A with an exemplary holographic image being depicted above the light wand, according to embodiments of the present invention. Projected holographic content 30 (e.g., images, data (such as time, date, and weather information), animations, and/or video) is shown projected by light wand 8.

[0039] It is noted that projected holographic content 30 can generally only be seen by an observer from a top view (i.e., perpendicular to transparent watch cover 6), or at perspectives having various angles deviating from such a top view. Projected holographic content 30 is shown in FIG. 3 from a side view in order to provide clarity with regard to the relation of projected holographic content 30 to transparent watch cover 6, light wand 8, and wand/face spacing 14.

[0040] As mentioned above with regard to FIG. 1A, producing a suitable holographic projection imposes additional constraints on the range of available height positions for light wand 8 (i.e., wand/face spacing 14). If wand/face spacing 14 is not sufficient, projected holographic content 30 of FIG. 3 will be distorted in appearance, displayed as blurry, partially obscured, flat (i.e., two dimensional), and/or lacking depth (i.e., not three dimensional). This is due to the opacity of opaque watch face 4 creating a “background distortion” (i.e., the “background” of light wand 8 induces the distortion, not a background in projected holographic content 30). Such distortion occurs in the generation of projected holographic content 30 if the proximity of opaque watch face 4 to light wand 8 is too close.

[0041] A useful measurement is to express wand/face spacing 14 as a percentage of face/cover gap 16, referred to as a “wand-spacing range.” Given that face/cover gap 16 places a finite limitation on the maximum height position of light wand 8 in order to prevent contact with other housing elements, the maximum value for the wand-spacing range is 100% (or nearly 100%) in order to achieve a desirable projection by generating projected holographic content 30 without any distortion. A threshold minimum value for the wand-spacing range is affected by opaque watch face 4 as described above, and is generally not trivial to determine.

[0042] Such a threshold minimum value for the wand-spacing range is a significant technical hurdle that has not been previously encountered. Distortions in the projection of projected holographic content 30, caused by light interference with opaque watch face 4, only occur due to close positioning of light wand 8 to opaque watch face 4, which is not a typical constraint found in most holographic applications. If light wand 8 is not positioned accordingly, a suitable 3D holographic projection will not be produced. That is, the proper positioning of light wand 8 is an essential and critical parameter to obtaining a proper holographic projection.

[0043] Experimental prototyping was used to determine the threshold minimum value for the wand-spacing range. Such assessments led to the conclusion that a wand-spacing range of less than about 40% of the total available gap (i.e., face/cover gap 16) produces improper, poor, and/or indiscernible projections.

[0044] It is noted that the interposition of transparent watch cover 6 between light wand 8 and projected holographic content 30 does not create any technical problems for displaying projected holographic content 30. Thus, projected holographic content 30 can even extend below transparent watch cover 6.

[0045] Light wand 8 can be programmed to edit the selection of projected holographic content 30 and/or to edit the display of projected holographic content 30 under various criteria for activation. Selection of projected holographic content 30 and activation criteria can be performed from a software application running on a PC or smartphone which can download the configuration data to watch base 2. In addition or alternatively, such setting selections can be performed by activation of adjustment buttons (not shown) located on watch base 2.

[0046] Such configuration data can be stored, for example, in a memory module (not shown) located in watch base 2. Watch base 2 can also house other peripheral components (not shown) such as communications modules (e.g., WiFi and Bluetooth), an interface connector (e.g., micro-USB), a charging connector, a spinner motor, a spinning-axis bearing, and standard watch elements to operate watch hands (hour, minute, and second), chronograph, and/or a date indicator.

[0047] FIG. 4A depicts a top view of the holograph-projecting watch device of FIG. 1A with an alternate, 2-spoked, light wand, according to embodiments of the present invention. An alternate, 2-spoked, light wand 40 is shown.

[0048] FIG. 4B depicts a top view of the holograph-projecting watch device of FIG. 1A with an alternate, 3-spoked, light wand, according to embodiments of the present invention. An alternate, 3-spoked, light wand 42 is shown.

[0049] FIG. 4C depicts a top view of the holograph-projecting watch device of FIG. 1A with an alternate, 4-spoked, light wand, according to embodiments of the present invention. An alternate, 4-spoked, light wand 44 is shown.

[0050] FIG. 4D depicts a side view of the holograph-projecting watch device of FIG. 1A with an alternate, stacked, multi-spoked, light wand, according to embodiments of the present invention. An alternate, stacked, multi-spoked, light wand 46 is shown. In such embodiments, the wand/face spacing (not shown) would be optimized from the lowest light-wand spoke in the “stack” of light wand 46.
