Immersive Multimedia Terminal
First Claim
1. A gesture recognition system comprising:
- one or more spatially-distributed acoustic emitters each configured for sending an ultrasonic acoustic signal;
a plurality of spatially distributed receivers each configured for receiving echoes produced when said acoustic signal is reflected by one or more spatially distributed objects and further configured to receive audible acoustic signals;
a timing-control circuit configured for controlling timing of emission of acoustic signals at each of the acoustic emitters and measuring timing of receipt of acoustic signals received at each of the receivers; and
a computing device configured to calculate characteristic information regarding the spatially distributed objects that reflect acoustic energy, to transform the characteristic information into a matrix of bits and to store the matrix of bits in memory, the characteristic information including a human gesture.

Abstract
Various embodiments of the present invention teach an advantageous means of conducting and controlling multimedia communication. Real-world communication involving sight, sound and body language is fully supported, without requiring that the user wear or touch any special apparatus. A novel Device-Area-Network (DAN) method is introduced to allow devices contained in compatible apparatus external to the Immersive Multimedia Terminal (IMT) to be discovered and fused to the devices within the IMT. Said method allows seamless integration of cellphones, laptops and other compatible apparatus so that they can use the IMT as a high-performance terminal. Said method also allows the IMT to fully integrate resources that exist in said external compatible apparatus. Examples of said resources are microphones, environmental sensors, disk drives, flash memory, cameras, and wired or wireless communication links.
