Cardboard Laptop

Instant laptop anywhere anytime.

So I read about a company that is developing a virtual keyboard that uses lasers to project a keyboard pattern onto a flat surface and to read the position of the user's fingers to allow you to "type" on a virtual keyboard. They envision using it with PDAs.

Then I did some research and found another company working on LPD's - Laser Projection Displays that allow you to project visual information (like the images of a computer monitor) against a wall or screen using lasers. Tiny little thing. They envision using it in cellphones and PDAs.

SO I thought - put it all together. A tiny box that uses lasers to project a screen in one direction and a keyboard in another, hooked up to the processing power of a PDA. A reporter in the field could make a laptop out of a couple scraps of cardboard.

       Um, Jinbish, was there an un-stated pun in your annotation about "thinking outside the (cereal) box", perhaps?
jurist, Dec 05 2002

       Wasn't intentional... I was going to follow up with a very poor 'cereal port' one though.

       Put a wristband on it, and it sounds like something Dick Tracey would use. As for a cardboard laptop, see link.
dalek, Dec 05 2002

       I'd love to see the patent. I don't think claims so broad as to cover "laptop made of paper" would be valid. For one, the laptop isn't made of paper - its made of lasers and a PDA. Of course, that doesn't mean I'm not quite sure people have patented tons of stuff in this area.

       I had a working SCSI server in an Airwalk shoebox and held together with duct tape.

       here's a link that shows a really small low power projection system. It's usable for a cell phone so it should work for a laptop size device

       You could also boast of the green factor! Check link (Real Cardboard Desktop).

       I've seen (in a chain e-mail) a 'laptop' made up of a series of 'pens' and a stand to put them all in pointing the right direction. One did the keyboard, one projected the screen onto a nearby wall (about regular monitor size), and a couple of others made up the mouse, battery etc.   

       It basically a desktop computer that fits in your top pocket (I guess with the processing power of a PDA if you're lucky though)!
