Abstract

A system and method are provided for presenting video content to a user. The method includes displaying video content on a visual display layer of a display device. The method further includes tracking, by a video processor, at least one object of interest in the video content. The method also includes embossing, based on respective positions of the at least one object, the at least one object on a microfluidics panel surface layer of the display device. The method additionally includes magnetizing, based on the respective positions, one or more portions of magnetic material in a magnetic material mesh layer of the display device to create respective temporary magnetics at the one or more portions that emit respective magnetic fields detectable by at least one user-wearable magnetic ring device held proximate to the display device. The respective magnetic fields indicate at least a movement of the at least one object.

First claim

What is claimed is:

1. A method for presenting video content to a user, comprising:
displaying the video content on a visual display layer of a display device;
tracking, by a video processor, at least one object of interest in the video content;
embossing, based on respective positions of the at least one object of interest, the at least one object of interest on a microfluidics panel surface layer of the display device;
magnetizing, based on the respective positions of the at least one object of interest, one or more portions of magnetic material in a magnetic material mesh layer of the display device to create respective temporary magnetics at the one or more portions that emit respective magnetic fields detectable by at least one user-wearable magnetic ring device configured to be circular and worn on a finger, held proximate to the display device, the respective magnetic fields indicating at least a movement of the at least one object of interest; and
tracking the at least one user-wearable magnetic ring device configured as an active electromagnetic cursor by the display device, wherein the display device tracks the active electromagnetic cursor relative to a grid formed by the magnetic material in a magnetic material mesh layer, and performs an action relating to the at least one object of interest responsive to one or more movements of the active electromagnetic cursor.

2. The method of claim 1 , wherein the at least one magnetic ring device is worn on at least one hand of the user.

3. The method of claim 1 , wherein the respective magnetic fields indicate the movement of the at least one object of interest by indicating a speed and a direction of movement of the at least one object of interest.

4. The method of claim 1 , further comprising, by at least the video processor:
monitoring hand movements of the user with respect to a movement of the at least one object of interest;
determining a usage pattern of the user with respect to tracking the movement of the at least one object of interest; and
adjusting a frame rate of the video content being displayed responsive to the usage pattern.

5. The method of claim 1 , wherein the visual display layer comprises a touch screen display layer or a Liquid Crystal Display layer.

6. The method of claim 1 , further comprising adjusting, by the video processor, a frame rate of the video content to coincide with a movement of at least one hand of the user.

7. The method of claim 1 , wherein said tracking step comprises tracking a position and a speed of the at least one object of interest.

8. The method of claim 1 , wherein said magnetizing step comprises applying current to the one or more portions of magnetic material to create the respective temporary magnetics at the one or more portions of magnetic material.

9. The method of claim 1 , wherein said magnetizing step comprises adjusting a magnetic force provided by the one or more portions of magnetic material responsive to a speed of the at least one object of interest.

10. A non-transitory article of manufacture tangibly embodying a computer readable program which when executed causes a computer to perform the steps of claim 1 .

11. A system for presenting video content to a user, comprising:
a display device,
wherein the display device includes:
a visual display layer for displaying the video content thereon;
a video processor for tracking at least one object of interest in the video content;
a microfluidics panel surface layer for embossing the at least one object of interest thereon based on respective positions of the at least one object of interest; and
a magnetic material mesh layer formed of magnetic material such that one or more portions of the magnetic material is magnetized based on the respective positions of the at least one object of interest to create respective porary magnetics at the one or more portions that emit respective magnetic fields, the respective magnetic fields indicating at least a movement of the at least one object of interest,
wherein the system further includes a user wearable magnetic ring device for detecting the respective magnetic fields when held proximate to the display device;
tracking the at least one user-wearable magnetic ring device configured as an active electromagnetic cursor by the display device, wherein the display device tracks the active electromagnetic cursor relative to a grid formed by the magnetic material in a magnetic material mesh layer, and performs an action relating to the at least one object of interest responsive to one or more movements of the active electromagnetic cursor; and
wherein each of the at least one magnetic ring device is configured to be circular and worn on a finger.

12. The system of claim 11 , wherein the at least one magnetic ring device is formed to be worn on at least one hand of the user.

13. The system of claim 11 , wherein the respective magnetic fields indicate the movement of the at least one object of interest by indicating a speed and a direction of movement of the at least one object of interest.

14. The system of claim 11 , wherein at least the video processor monitors hand movements of the user with respect to a movement of the at least one object of interest, determines a usage pattern of the user with respect to tracking the movement of the at least one object of interest, and adjusts a frame rate of the video content being displayed responsive to the usage pattern.

15. The sytem of claim 11 , wherein the visual display layer comprises a touch screen display layer or a Liquid Crystal Display layer.

16. The system of claim 11 , wherein the video processor adjusts a frame rate of the video content to coincide with movement of at least one hand of the user.

17. The system of claim 11 , wherein the video processor tracks a position and a speed of the at least one object of interest.

18. The system of claim 11 , wherein a magnetic force provided by the one or more portions of magnetic material is adjusted responsive to a speed of the at least one object of interest.
