3D sensor technologies ready for consumer space expansion

In this entry, Jeff Bier, Founder of the Embedded Vision Alliance and president of BDTI, discusses how new vision sensor technologies, high-performance system architectures, and algorithms that are gaining acceptance in the consumer market.

In the consumer market, one of the most interesting uses of new vision technologies is the creation of new types of user interfaces that are more natural for users. The biggest success in this space so far is Microsoft's Kinect for its Xbox game console, which has sold more than 20 million units. Recently I spoke with Tim Droz, who was previously head of entertainment systems sensor development at Canesta. Tim is now VP and GM of US operations for the 3D sensor development company SoftKinetic.

I asked Tim about Intel's "Perceptual Computing" initiative, which aims to bring gesture control and other new user interface technology to personal computers. As part of Intel's Perceptual Computing initiative, Creative Technologies recently announced the Senz3D camera, which is a PC accessory that senses close-range 3D to track fingers, hands, face, and torsoin contrast with the Kinect, which works at longer ranges and tracks large-scale movements of players' bodies, such as kicking and jumping.

The Senz3D camera is based on SoftKinetic's DepthSense time-of-flight sensor. The sensor is a 320x240 depth array and outputs a 30 to 60 frame-per-second depth map of the PC user from 15cm to 1m away. The camera also sports a 720p HD colour sensor and stereo microphones.

Building on this camera hardware, the Perceptual Computing software platform senses hand and finger gestures using a custom gesture algorithm library, which is also from SoftKinetic, and also adds augmented reality, facial analysis, and speech recognition. Intel presents these libraries in an SDK API, which eliminates the need for application developers to manipulate raw sensor data, freeing them to focus on designing rich natural user experiences.

The Senz3D camera will be shipping in October. The core camera module is now also integrated into Intel's new Portable All-In-One (pAIO) reference design, which was announced and demonstrated at the Intel Developer Forum in September.

Will gesture user interfaces become mainstream for PCs, as they are becoming for game consoles? Only time will tell, but it seems clear that the combined efforts of companies like Intel, Creative Technologies, and SoftKinetic increase the chances of 3D sensing catching on in PCsand elsewhere.

If you want to learn more about incorporating visual intelligence into products, please join me on October 2 for the Embedded Vision Summit in the Boston area. The Summit is a technical educational forum for engineers interested in incorporating visual intelligence into electronic systems and software and will include a full day of presentations and demos.
