How to Turn a Flat Surface into a Touchscreen

How to Turn a Flat Surface into a Touchscreen?

Light Touch™ is an interactive projector that instantly transforms any flat surface into a touch screen. It frees multimedia content from the confines of the small screen, allowing users to interact with that content just as they do on their hand held devices – using multi-touch technology.

Light Touch™ has Holographic Laser Projection (HLP™) technology inside which creates bright, high-quality video images in WVGA resolution. Integrated infrared sensors detect motion and turn the projected image into a 10.1″ virtual touch screen, so the user can control the projector and interact with applications simply by touching the image.

Light Touch™ has a Windows CE operating system and runs Adobe Flash Lite, making it a versatile platform, ideal for realising new uses. Built in Wireless Networking capability connects applications directly to the internet, immediately opening up rich functionality such as social networking, multimedia sharing and electronic point of sale.

What is Holographic Laser Projection

See How Holographic Laser Projection Works?

Holographic Laser Projection – or HLP™ – is a revolution in display technology. The term holographic refers to the inventive method we use to create 2D images.

Using holographic algorithms, we transform the image we want to project into sets of diffraction patterns, which are shown on a tiny microdisplay. When laser light illuminates the microdisplay, the projected image is formed by diffraction.

Diffraction patterns are highly efficient. Instead of blocking light, they steer light to exactly where it is needed and away from where it is not. Calculating the diffraction pattern for each high quality image would be too computationally intensive.

By calculating multiple patterns, each of which forms a rough version of the image. When viewed in rapid succession, the eye evens out the noise and perceives a single, clearly defined image. So you get efficient, high quality video in real time.

Using lasers means colours appear rich and vivid, and the image is always in focus. HLP™ technology also projects perfectly onto curved surfaces. Its uniquely wide throw angle creates large images very close to the projector. And HLP™ has a class 1 laser safety classification, making it completely eye safe.

These features enable to integrate infrared sensing technology and create an interactive projector that instantly transforms any flat surface into a touch screen.
