Here’s a really cool demo of an interactive projector screen or is it Multi-Touch Projector?

The basic idea is really simple: a program running on the PC will process the images viewed from the webcam, find the position of the penlight/light spot, and use this position to deternine where to place the mouse cursor on the screen. Now, if we can assume that the light spot/point is always the brightest object in the area, than the detection algorithm will be very simple: find the location of the pixel with the highest intensity level. We make use of two additional useful facts: 1. a normal pocket touchlights (or any incandescent lamp for that matter) actually emits several times more infrared light than visible light, and so works better as IR point source than a visible light source. 2. most webcam are able not only to detect visible lights (red, green and blue, etc) but they can also detect infrared (IR) lights – for example as emitted by the IR LEDs commonly found on TV/Hifi remote controls – which are invisible to the human eyes. So if we can somehow use the webcam to capture only the infrared lights from our light source and reject the surrounding visible lights, we will be ensured of a very reliable system. An additional feature of this system will be it will work if we replace the torchlight with any IR LEDs.”

Check out this cool DIY on how to build your own 3D motion sensing controller.

Make a 3D interface using an six resistors, aluminum foil, and an Arduino. Take that, Wii.

The basic goal here was to make a 3D position sensing system that most people can build, while still preserving some semblance of functionality. To get an idea of possible applications, check out the demo video. If you think you can build one that is simpler and equally accurate, or slightly more complex and more accurate, share in the comments!

Okay, I do bash Microsoft a lot but here’s a really cool multi-touch demo from Microsoft!

The thing is running Dell’s Latitude XT Tablet, one of Microsoft’s core monolpoly gang banger members.

Ha, this has to be the most technologically advanced light bulb that consumers can buy right now.  It’s basically got LEDs and a microcontroller to control the whole schbang.

EvoDim allows for maximum energy conservation by allowing the user to cycle the bulb through three different output settings (250 Lumen, 750 Lumen, 950 Lumen) simply by rapidly switching the bulb on and off. The EvoLux R effortlessly goes from a room filling light all the way to a night light with a turn or flip of a switch. There is no need for a dimmer switch as EvoDim turns every fixture into a dimmable fixture instantly. Watch a demo of EvoDim Technology Below

ESPN remote is here! Well, at best, it’s really bringing the TV Guide to your remote, which is a genius idea in itself. Looks like they are going to get like million orders before they even start selling it.

Looking for an alternative to the Harmony? It now exists. As I was leaving the floor at the Cable Show, I got the lowdown on the new Ultimate Remote from tvCompass. In a quick demo I was particularly impressed with the TV Guide EPG rendering - not an easy thing to get right on such a small screen. Even more important, however: the remote is WiFi-enabled, meaning plenty of extras like messaging and content applications. It’s launching with ESPN and associated sports content, but the partnership opportunities are really limitless.

I believe speech controlled wheel chairs have been around for years but here’s a DIY version.

[Amnon] sent in this demo of his groups voice controlled wheel chair. I couldn’t find any details, but sometimes just a demo is enough to find some new inspiration. They connected a hm2007 speech recognition kit to an Innovation FIRST controller board on an electric wheel chair chasis. Additional sensors detect stairs and other obstacles.

Adobe Flex, will it be the next generation technology for Web 3.0? It’s hard to tell at this point as SEO (Search Engine Optimization) for flash or flex has not proven to be great. Although you could make an opinion that flash or flex can be embedded in an HTML page, that’s still no where close to RSS and tags that blogs offer.

Today, I met when Steven (Stephen) Harris from WebSpiders.com, a Global IT Outsourcing company that specializes in development of Adobe Flex and AJAX web applications.

Steven was nice enough to show me a demo of how Flex will change how people shop online:

P.S. Excel Man was also spotted over at Expressocorp.com’s booth. (Now I think of it, there’s a guy inside it. Tomorrow, I will punch the Excel Man and see if I can get a reaction.)

What do you think of Adobe Flex?
