Soladapt's Touchscreen Overlay presents the unique and cost effective opportunity to experience the full functionality of touch-based UIs like Windows 8.  Simply put, it's a pane of toughened glass you put over the front of your display and plug in via USB, giving you Touchscreen capabilities.

Using Infrared Touchscreen Technology (similar to what you see in the first generation Kindle Touch), small LEDs are built into the frame, which can register a maximum of 2-point multi touch.  Not what is truly capable of purpose built Touch displays; but the overlay is still more than functional, and it'll be a rarity to use more than two fingers.

"We are delighted to introduce the Touchscreen Overlay to the UK consumers and trade at the Gadget Show Live," Richard Plaskow, Co-Founder of Soladapt commented.  "With endless applications in the home, office and education sector we are aiming to establish the Touchscreen Overlays as a cost effective and environmentally friendly alternative to all those who have a non touchscreen monitor already."

With compatability with PC/Mac/Android, this small UK business have something good here.  A way into what can be a pricey market, without sacrificing the technology you have invested in so far.
