Abstract

Embodiments of the present invention embody motion detection via a camera for mobile platform video gaming and exercise, in either integrated or separately attachable components. The system includes an oral care device. The oral care device, such as a toothbrush, includes one or more targets. Each target designates a specific area of the toothbrush, such as back side, a front side, a brush head or a brush end. A target can be a color or a tag, and can be removably coupled or integrally formed with the toothbrush. The system also includes an application configured to detect the targets, to determine that a property of any of the targets has changed. Based on at least the determination, the application is configured to monitor progress of brushing and to control an element in the application.

Claims

1. In a toothbrush having a head, a neck and a handle, the improvement comprising the handle including a first portion coupled with the neck, and a second portion removably coupled with the first portion at an end of the handle that is furthest from the head and shorter in length than the first portion of the handle, and at least one passive marker located at the second portion of the handle and configured to aid in tracking by a computing device of a brushing trajectory, wherein the second portion is marked using two tags, wherein each of the tags is one of an augmented reality (AR) marker, a bar code, and a quick response (QR) code.

2. The toothbrush of claim 1, wherein the toothbrush is separate and distinct from the computing device.

3. The toothbrush of claim 1, wherein the second portion of the handle includes a tip of the handle.

4. The toothbrush of claim 1, wherein the at least one marker is integrally formed with the second portion of the handle.

5. The toothbrush of claim 1, wherein the at least one marker is removably coupled with the second portion of the handle.

6. The toothbrush of claim 1, wherein the second portion includes two receptacles each for receiving one of the tags.

7. The toothbrush of claim 6, wherein each of the receptacles are located on opposite faces of the second portion of the handle.

8. A toothbrush comprising:

a. a first portion including a first passive marker that is detectable and trackable by an external computing device that is separate from the toothbrush; and

b. a second portion including a second passive marker that is also detectable and trackable by the external computing device, wherein the second portion is a part of a detachable section of a toothbrush handle that is removably coupled to the rest of the toothbrush handle at an end of the toothbrush handle that is furthest from a brush head of the toothbrush, wherein the detachable section of the toothbrush handle is shorter in length than the rest of the toothbrush handle, and wherein each portion is marked using a tag, wherein the tag is one of an augmented reality (AR) marker, a bar code, and a quick response (QR) code.

9. The toothbrush of claim 8, wherein the second portion is marked differently from the first portion for separate tracking.

10. The toothbrush of claim 8, wherein the first portion includes the brush head.

11. The toothbrush of claim 8, wherein when the toothbrush is in a first position, the first portion and the second portion are visible, and wherein when the toothbrush in a second position, only the second portion is visible.

12. The toothbrush of claim 8, wherein the first portion is also a part of the detachable section of the toothbrush.

13. The toothbrush of claim 8, wherein each of the portions is trackable by a brushing application executing on the external computing device to monitor progress of brushing based on at least one of angle, orientation, location and dimensions of the each of the portions in a view of a camera changes.

14. The toothbrush of claim 8, further comprising a receptacle for receiving the tag.

15. A toothbrush comprising:

a. a first receptacle and a first tag located on a first area of the toothbrush, wherein the first receptacle for receiving the first tag;

b. a second receptacle and a second tag located on a second area of the toothbrush, wherein the second receptacle for receiving the second tag; and

c. a third tag located on a third area of the toothbrush, wherein each of the tags is visually different from the other tags, wherein the third area is located at a bristle end of the toothbrush, and the first area and the second area are located at a removable end that is distal from the bristle end, wherein the first area and the second area are on opposite sides of the removable end.

16. The toothbrush of claim 15, further comprising:

a third receptacle located at the third area, the third receptacle for receiving the third tag, wherein the first tag, the second tag and the third tag are removable from the toothbrush.

17. The toothbrush of claim 15, wherein the tags are visually colored.

18. The toothbrush of claim 15, wherein the tags are one of augmented reality (AR) markers, bar codes, and quick response (QR) codes.
