Hitachi hopes to become the first major TV maker to sell sets that respond to gesture commands, such as those used on the Wii. Technology has advanced to the point where gesture-based systems are moving into the TV and PC markets.
Improved cameras in these devices can detect how far away an object is from the lens, making interpretation of movement far more accurate. Prices are expected to fall enough that it will be possible to build them into televisions.
Consumers then will be able to sit in a chair 10 feet away and rotate a hand to raise the volume on a TV.
Hewlett-Packard says it hopes to include gesture technology late this year in certain products.
