3 years ago multi touch screens were  experimental .

Today with the iPhone, fingers are now part of the human - computer interaction.

Things are changing fast and multi-touch is becoming more more affordable and more software is built with touch in mind.

I was at Microsoft Monday for a demo and hands on with some User Interface products. Lynn Langit demo’ed five point multi touch software possibilities on an $800 HP laptop running Windows 7. Even if it was nice, I am still not convinced it will make a significant difference in improving user interactions with their laptop.   Still, it will be nice to have and a good addition to the mouse.

Next, Wood Pewitt let us play with the Surface and that’s something else. It’s a table, the smartest table I know. Keeping it in the context of a table I can see a lot of possibilities for this. It’s very engaging — the touch has a great feel and I can see it in restaurant, bars, airports … even homes. To order your food, drink, tickets, play casual games, organize your media, select a movie to see….. Its currently at $10,000 but I bet we will see multi-touch  tables at $2,000 in fewer than 2 years and $500 ones in 4 years.
