Our lovely class visited Interaction Innovation Lab in Gardens Point Campus. What a really exciting tour.
The CUBE is established by fifty-two pieces of 55 inch FHD interactive screen, which is provided by MULTITACTION, and 15 high-lumens Panasonic projectors. To track the different users’ hand motion, each of the interactive screen has 32 Integrated Backlight Emitter Camera Modules (Infrared Tech) to detect the touch points, and the up to 200fps tracking speed allows the devices to detect the dragging, long-pressing gestures.
The G-Speak Gloves is an innovative hand gestural tracking technology, which is created by Oblong. In the VISER Lab, Adam uses these gloves and infra-red camera rig to transfer the hand motion to compute reflection. Basically, there are several sensors on the gloves, the user can ware these gloves before a screen, through tracking the relative hand position in three dimensions, the signal can be transfer to the computing system and recognized as the gesture command, so that it can realise the hand motion to interact with the object on the screen.
            Leap Motion
Leap Motion is a commercial hand gesture tracking device It is a tiny device, even smaller than a mobile phone, but it is installed with two infrared camera sensors and illumination LCDs to capture the hand’s 3D image over the device. Assisting with the official motion analysis software, the hands, fingers, arms’ action would transfer to motion data, so that these data can be utilized in controlling interaction. In addition, the Leap Motion published its official SDK for developer to customise their software with the motion data. Further, it provides an app store to let users use the related applications. This created a new era of personal computing interaction.
  SICK Laser Tracking System
SICK is a high-tech industrial equipment producing company that provides industrial laser scanning device solutions. In ViSER Lab, Adam utilizes its industrial laser scanner to realize the 2D position tracking. Basically, there are 4 scanners in the four corners of the lab room. Each of the devices (Sick LMS 100-10000 Laser Scanner) can produce laser to scan the object within 30m distance and 270-degree range. The laser light shot from the device, when it irradiate the object, it would reflect back, and then the sensor would automatically calculate the distance between the object and the scanner. Owing to there are four sensors from four directions, the computer can integrate the four signals into a 2D matrix, so the object’s relative position would be tracked.
