Interactive Whiteboard System (EyeRIS) Smart Classroom

EyeRIS is the ground-breaking, feature-rich and portable interactive whiteboard system based on the pioneering Visual Touch platform from Cybernetyx which supports Multitouch, Multiuser and gesture based interaction on about any surface.”
The term Multitouch refers to the ability not only to detect physical   touches and movements on a screen, but to detect and track multiple touches and movements simultaneously. Touch events are similar to mouse events, except that you can receive and track more than one of them at once, and touch events do not support mouse-specific concepts such as hovering.

Qualities of Interactive Whiteboard

Surface Independent:
While other IWB solutions in the market are board-based solutions, EyeRIS device stands out to be completely surface independent. It gives you freedom to operate any area of the screen without having to strain yourself.

Multi-Touch Multi-User Interface:
EyeRIS has an intrinsic support for iPhone like gesture based multitouch control over the applications. EyeRIS is the only interactive solution in the industry today to support more than 255 simultaneous touches on the board.

EyeRIS is today, arguably, the smallest interactive whiteboard system in the world with a size of 3”X2”X1.5”, and weighing under 300 gms. It is about 100 times lighter than the general board based solution. Unlike other solutions in the market, EyeRIS device can be mounted on the ceiling with the projector, thus preventing acts of vandalizing seen with board based solutions.

Interactive Area:
EyeRIS supports one of the industry’s largest size of 160” diagonal, and is an optimum solution for large audiences and larger rooms.

Extendable, Occlusion-free Stylus Pens:
Due to its unique telescopic design, a standard EyeRIS pointer allows you to reach the obscure corners of the screen. In addition, all EyeRIS e-pens are implemented on an award-winning Sword-FishTM design which eradicates the problems of occlusion faced with several interactive whiteboard solutions in the market today.

Visual Touch Software:
EyeRIS is based on the pioneering Visual Touch optical tracking engine for unmatched writing performance and comfort. It comes with an out-of-the-box compatibility with all windows applications and with several web based e-learning solutions.

Unique Laser based calibration for faster setup:
EyeRIS device uses an inbuilt laser mechanism to assist the entire process of calibration so that the entire interactive whiteboard setup can be completed within 10 seconds.

Temperature Senor LM35

Precision Centigrade Temperature Sensors General Description: The LM35 series are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. The LM35 thus has an advantage over linear temperature sensors calibrated in ?Kelvin, as the user is not required to subtract a large constant voltage from its output to obtain convenient Centigrade scaling. The LM35 does not require any external calibration or trimming to provide typical accuracies of ? ? ?C at room temperature and ? ? ?C over a full -55 to +150?C temperature range. Low cost is assured by trimming and calibration at the wafer level. The LM35's low output impedance, linear output, and precise inherent calibration make interfacing to readout or control circuitry especially easy. It can be used with single power supplies, or with plus and minus supplies. As it draws only 60 mA from its supply, it has very low self-heating, less than 0.1?C in still air. The LM35 is rated to operate over a -55 to +150?C temperature range, while the LM35C is rated for a -40 to +110?C range (-10? with improved accuracy). The LM35 series is available packaged in hermetic TO-46 transistor packages, while the LM35C, LM35CA, and LM35D are also available in the plastic TO-92 transistor package. The LM35D is also available in an 8-lead surface mount small outline package and a plastic TO-202 package. Features: Y Calibrated directly in ? Celsius (Centigrade) Y Linear a 10.0 mV/?C scale factor Y 0.5?C accuracy guaranteeable (at +25?C) Y Rated for full -55? to +150?C range Y Suitable for remote applications Y Low cost due to wafer-level trimming Y Operates from 4 to 30 volts Y Less than 60 mA current drain Y Low self-heating, 0.08?C in still air Y Nonlinearity only ? ? ?C typical Y Low impedance output, 0.1 ohm for 1 mA load
