It's one step removed from the Midas approach, but Bill Gates wants to turn nearly everything we touch into a computer.
Speaking to a crowd of CEOs gathered in Redmond, Washington DC, Gates showed off prototype technology he said will allow home and office walls to become computers.
While Microsoft's Surface computers are currently shipping for about US$10,000, Gates said the hardware costs for such products need not be that high. Within a few years, it could be in the hands of individuals.
"We're saying it will be absolutely pervasive," Gates said. "When I say everywhere, I mean the individual's office, the home, the living room."
What Gates showed on Wednesday was a 4-foot-by-6-foot prototype called TouchWall. Among the things that would appeal to business users was the idea that presentations might shift away from the sort of robotic slideshows enabled by PowerPoint.
Along with TouchWall, Gates showed off the software that accompanies it, known as Plex. TouchWall itself uses infrared and laser technology to sense touch input, Microsoft said.
In his speech, Gates also proved why TouchWall is still in the prototype stage.
"Whenever I go up and touch it, the software will notice it," Gates said, in kicking off the demo. When nothing happened, he added the qualifier "theoretically".
The screen did come to life a few minutes later.
He might be touching his screen, but is sounds like he has hid hand on something else. I personally can't think of anything remotely useful for people or society with this hyped up touchscreen.
