Sony Mobile Communications Inc will release "Xperia Touch G1109," which projects an image on a wall, floor or desktop and enables to use the projected image as a touch panel, June 26, 2017.

The size of the projected image is equivalent to 23-80 inches, and the distance between the G1109 and the projected image is 0-25cm. Though there is no manufacturer's suggested retail price, its expected retail price is ¥150,000 (approx US$1,365, ¥149,880 excluding tax at Sony Store). It will be sold as both residential and commercial devices.

Sony released "Portable Ultra-short Focus Projector LSPX-P1" Feb 13, 2016. And the G1109 is a product that seems to have been developed by adding a touch panel function to the LSPX-P1. It is equipped with WiFi capability and Android 7.0 and basically supports applications available at Google Play. It is like a giant tablet computer that can be operated by multiple users.

The width and weight of the main unit are about 6.9cm and 932g, respectively. The G1109's ultra-short focus lens module, "SXRD" LCD display device module and laser light source module, which are three major elements for realizing an ultra-short focus projector, are almost the same as those of the LSPX-P1.

Touch operation was realized with an infrared module near the lower part of the lens (on the projection side), and reflected light is received by an image sensor via the lens module. The detection frequency is 60fps, and up to 10-point multi-touch input is possible. Equipped with a lithium-ion (Li-ion) rechargeable battery, the G1109 can be continuously used for about an hour without an external power source.
