  2. Collaborative Digital Canvas Concept: This project will allow children to enjoy painting in real time on a collaborative digital canvas regardless of physical location. This project will integrate smart phones, wands with off-the-shelf embedded components and the display system. Motivation: Existing remote collaborative painting systems are usually web based and the modes of input required are used unsuitable for children. With our system, children will be able to collaborate using a simpler pointing mechanic to paint.

  3. Competitive Analysis • Imagination cubed: an online collaborative whiteboardhttp://www.imaginationcubed.com/Our project supports a wider variety of input methods that are suitable for children to use and supports more simultaneous users. • Wii: A potential competitor to our system. All that is required is a software component. http://www.wii.com/Our project has remote modes of input via cell phone side applications.

  4. Requirements • Functional requirements: Accepts user and sensor (accelerometers and magnetometers) inputs and converts data to positions and effects on the canvas. • The system will have a defined network protocol to allow for interoperability between multiple client (wand, cell phone) and server (local projector / system) devices. • Timing requirements: Any changes on canvas will take less than half a second to take effect. • Reliability requirements: The system will degrade gracefully from connection loss • Security requirements: The server will support an authentication and connection limiting systems for remote users (smart phones, other servers)

  5. Technical Specification • X86 computer • Projector • Smart phones equipped with accelerometers and magnetometers • ADX 1345: three-axis accelerometer with high resolution (13-bit) measurement up to ±16g • HMC6352: 0.5 degree heading resolution1 to 20Hz selectable update rate • AVR 28 Pin 20MHz 32K 6A/D - ATMega328:23 I/O lines, 6 of which are channels for the 10-bit ADC, runs up to 20MHz • XBee 1mW Chip Antenna: 300ft (100m) range, 250kbps Max data rate, 3.3V @ 50mA
