On May 17, 2011 Ryersons’ Interactive Computing Applications and Design Group (ICAD) demonstrated their latest projects. The session starts with a demonstration of using Microsoft Kinect hardware to control a computer mouse. Next, the group shows the use of a gestural interface to control Google Earth, followed by a demo of using Kinect to control a avatar in Second Life.
The session continues with a demonstration of a potential application to control a small arduino based robot over bluetooth using gestures. Following this the ICAD staff show the use of Kinect as a tracking and control mechanism for a Point-Tilt-Zoom (PTZ) camera. This approach allows them to track up to five people without active trackers. The data from the Kinect camera is used to instruct the PTZ camera where to “look”. Once a person is identified (by putting up their hand) the kinect will try to track the person around the room and make sure the PTZ camera follows the person as well. Switching the tracked person is done by raising ones hand.
Their last demo will show a gestural based keyboard that will eventually be tied into a interactive phonebook application where the user can type the name of a contact using gestures and automatically dial the number through a voip application (ie: google talk).

Great little video on how to setup AR marker recognition under QC. Even has a nice mellow background music :-).

Galaxy sub-brand KFA2 has just announced their new KFA2 GTX460 WHDI nvidia based wireless graphics card. The KFA2 GTX 460 WHDI uses a wireless link (WHDI) to send the display output from your PC to your screen. You just need to attach the bundled receiver to the back of your monitor/screen and you’re done.
The card’s name comes from Amimon’s wireless technology – WHDI stands for Wireless Home Digital Interface. WHDI 1.0 provides a high-quality, uncompressed wireless link which supports data rates of up to 3Gbit/s (allowing 1080p) in a 40 MHz channel, and data rates of up to 1.5Gbit/s (allowing 1080i and 720p) in a single 20 MHz channel of the 5 GHz unlicensed band, conforming to FCC regulations and worldwide 5 GHz spectrum regulations. Range is beyond 100 feet (30 m), through walls, and latency is less than one millisecond. The WHDI standard supports HDCP 2.0, so it can route protected content (Blu-ray films, for example) without a problem.
Aside from having five aerials rather than display outputs, the card is a typical GeForce GTX 460 1GB affair. It supports Nvidia’s PhysX and CUDA technologies, and it’s DirectX 11-compatible. NICE, I want one :-).
So how do you emulate the human vision system. Well if you ask either Nicolos Pinto, David Cox or James DiCarlo, they’ll probably point at the harmless looking machine sitting in the corner of their lab. The machine in question is “quietly” humming away as it tries to simulate a real-time human level artificial vision system using it’s 8 (YES EIGHT) 9800GX2 NVIDIA graphics cards. Have a quick look at this flickr album to get an idea of the size of this beast :-).
Head over to youconvertit.com. I’ve been waiting for something like this since the early days of the web and it seems like these people have done it. It’s simple, go to the site, upload your file and choose which format you want to convert it to. Give them your email address and they will send you a link to the converted file when it’s done. simple.
They can handle more than 70 different types of graphics, 40 different document formats, 7 different types of audio files and more that 10 different video file formats. As a bonus they also allow you to do unit conversion :-)
