Microsoft Surface Touch Table: Samsung SUR40
The Samsung SUR40 is an interactive surface that caters to 360° multiuser applications with the aid of Microsoft's PixelSense technology. The system's IR backlight unit provides the light that will be reflected back onto the integrated sensors when the screen is touched. Values reported from all the sensors are used to create a picture of what is on the display. This technique allows the SUR40 to detect fingers, blobs, and tagged objects. The Vislab is currently using the SUR40 as a multitouch control station for our cluster-driven tiled display, Stallion.
| Operating System | Windows 7 |
| Screen Size | 40" LCD |
| Screen Resolution | 1920 x 1080 |
| Graphics Card | AMD Radeon HD 6570M |
| Multi-Touch Characteristics | Uses PixelSense technology to process a maximum of 50 touch points simultanously from fingers, hands, and/or objects |
Google Glass x2
Google Glass is a type of wearable technology with an optical head-mounted display (OHMD). It was developed by Google with the mission of producing mass-market ubiquitous computing. Users rely on touch and voice commands to communicate with the Glass interface. The Vislab is equipped with two pairs of Google Glass.
| Display | Optical head-mounted display equivalent of a 25in. HD screen from 8ft. away |
| Camera | 5MP photos, 720P video |
| Audio | Bone Conduction Transducer |
Raspberry Pi (Model B) x4
The Raspberry Pi is a low cost, credit card-sized, single-board computer that is compatible with a variety of ARM Linux distributions. Raspberry Pis have been used by Vislab researchers to drive various experimental machines such as wearable, cloud-based visualization systems and portable, cluster-driven tiled displays.

Leap Motion Sensor x3
The Leap Motion Sensor is a hardware controller that relies on infrared cameras and LEDs to create a more natural, touchless user interface that converts hand/finger gestures into three-dimensional computer commands.
| Dimensions | 0.5" x 1.2" x 3" |
| Frame Rate | >200 fps |
| Resolution | tracks all 10 fingers up to 1/100th of a millimeter |
| Range | 8 cubic feet of interactive space |
