Light Blue Optics has just announced their product called the ‘Light Touch’, which is a laser-based projector that turns virtually any flat surface into an interactive touchscreen! It works somewhat like a laser keyboard, except that the Light Touch projects coloured images.
The Light Touch is capable of projecting WVGA sized, auto-focusing images via its proprietory holographic laser projection technology (HLP), and it detects for touch using an infra-red sensing system. It also features WiFi and Bluetooth, allowing internet connectivity and the use of various bluetooth devices. Although the on-board memory is only 2GB, it has a microSD card slot that supports up to 32GB. The reported battery life is 2 hours. The practical applications of this device is absolutely mind blowing. Look out for the product launch (invite-only) at the CES 2010 tomorrow.
