Invisible computing comes to Asia tech expo

---

HONG KONG, Dec 14 (AFP): A robotic cook, a colouring book that comes to virtual life and movies that read your mind are some of the innovations on show at a cutting-edge computer technology exhibition in Hong Kong this week. The first Asian edition of the SIGGRAPH expo of computer graphics, interactive technology and digital media brings together developers, distributors and resellers from around the world. But while most of the conference is about business, some of the most interesting-and just plain bizarre-gadgets are not for sale. The "emerging technologies" hall is where the real boffins from universities and research laboratories strut their stuff with prototypes fresh off the drawing board, in the name of science rather than profit.
