Abstract

According to one implementation, a stereoscopic image display system includes a computing platform having one or more hardware processor(s), a system memory storing a software code, an autostereoscopic display, and a user tracking unit controlled by the hardware processor(s). The hardware processor(s) execute the software code to utilize the user tracking unit to detect a left eye location and a right eye location of a user of the stereoscopic image display system, and to determine a left eye image and a right eye image corresponding to an output image of a content being played out by the stereoscopic image display system based on the respective left eye location and right eye location of the user. The hardware processor(s) further execute the software code to render the left eye image and the right eye image using the autostereoscopic display to generate a three-dimensional (3D) image of the output image.

First claim

What is claimed is:

1. A stereoscopic image display system comprising:
an autostereoscopic display including a computing platform having at least one hardware processor and a system memory storing a software code; and
a motor coupled to a rotor for rotating the autostereoscopic display, the motor controlled by the at least one hardware processor;
the at least one hardware processor configured to execute the software code to:
spin the autostereoscopic display about a spin axis at a spin rate using the motor and the rotor;
identify an angular location of a user of the stereoscopic display system relative to a circle concentric with the spin axis;
detect a left eye location and a right eye location of the user relative to the angular location of the user;
determine a left eye image and a right eye image corresponding to an output image of a content being played out by the stereoscopic image display system based on the respective left eye location and the right eye location of the user; and
render the left eye image and the right eye image using the autostereoscopic display while spinning when the autostereoscopic display faces the user, as determined based on the angular location of the user and the spin rate.

2. The stereoscopic image display system of claim 1 , wherein the left eye image and the right eye image rendered using the autostereoscopic display produce a three-dimensional (3D) image of the output image for the user.

3. The stereoscopic image display system of claim 1 , wherein the autostereoscopic display comprises a display screen configured to render two-dimensional (2D) images, having one of a lenticular lens or a parallax barrier covering the display screen.

4. The stereoscopic image display system of claim 3 , wherein the display screen is one of a liquid-crystal display (LCD) screen or an organic light-emitting diode (OLED) display screen.

5. The stereoscopic image display system of claim 1 , wherein the autostereoscopic display comprises a compressive light field display.

6. The stereoscopic image display system of claim 1 , further comprising a privacy filter affixed over a display screen of the autostereoscopic display.

7. The stereoscopic image display system of claim 1 , wherein the at least one hardware processor is further configured to execute the software code to strobe the autostereoscopic display using at least one of a backlight of the autostereoscopic display or an external light source when the autostereoscopic display faces the user.

8. The stereoscopic image display system of claim 1 , wherein the autostereoscopic display is integrated with one of a smartphone or a tablet computer.

9. A stereoscopic image display system comprising:
an autostereoscopic display including a computing platform having at least one hardware processor and a system memory storing a software code; and
a motor coupled to a rotor for rotating the autostereoscopic display, the motor controlled by the at least one hardware processor;
the at least one hardware processor configured to execute the software code to:
spin the autostereoscopic display about a spin axis at a spin rate using the motor and the rotor;
identify an angular location of each of a plurality of users of the stereoscopic display system relative to a circle concentric with the spin axis;
detect a left eye location and a right eye location of each of the plurality of users relative to the angular location of the each of the plurality of users;
determine a left eye image and a right eye image corresponding to an output image of a content being played out by the stereoscopic image display system for each of the plurality of users based on the respective left eye location and the right eye location of the each of the plurality of users; and
render the left eye image and the right eye image for each of the plurality of users, using the autostereoscopic display while spinning, the autostereoscopic display faces the each of the plurality of users, as determined based on the angular location of the each of the plurality of users and the spin rate.

10. The stereoscopic image display system of claim 9 , wherein the left eye image and the right eye image rendered using the autostereoscopic display produce a three-dimensional (3D) image of the output image for the each of the plurality of users.

11. The stereoscopic image display system of claim 9 , wherein the autostereoscopic display comprises a display screen configured to render two-dimensional (2D) images, having one of a lenticular lens or a parallax barrier covering the display screen.

12. The stereoscopic image display system of claim 11 , wherein the display screen is one of a liquid-crystal display (LCD) screen or an organic light-emitting diode (OLED) display screen.

13. The stereoscopic image display system of claim 9 , wherein the autostereoscopic display comprises a compressive light field display.

14. The stereoscopic image display system of claim 9 , further comprising a privacy filter affixed over a display screen of the autostereoscopic display.

15. The stereoscopic image display system of claim 9 , wherein the at least one hardware processor is further configured to execute the software code to strobe the autostereoscopic display using a backlight of the autostereoscopic display when the autostereoscopic display faces the each of the plurality of users.
