Touchjet was invited at this year's Engadget Expand event and bringing with them the smallest projector I've seen in the market; TouchPico which is an interactive Android PC with projector capabilities. The device features an Android desktop similar to standard Android phones. TouchJet demonstrated the TouchPico at the Engadget Expand and I was able to see myself using this in business meeting showing off a presentation by touching it to control the slides without an interactive smart-board.
The TouchPico interface works just like any Android phone. Its projector capabilities are due to a built-in infrared camera that simulates touch input from the screen and tracks the stylus’ movements. The device is also equipped with several unique features, including screen-casting, HDMI output, an SD memory card, air mouse support, Bluetooth capabilities and audio output. The screen can project as big as 80 inches. Currently, the TouchPico is available for preorder on touchjet.com.
