d.tools is a hardware and software system that enables designers to rapidly prototype the bits (the form) and the atoms (the interaction model) of physical user interfaces in concert. d.tools was built to support design thinking rather than implementation tinkering. With d.tools, designers place physical controllers (e.g., buttons, sliders), sensors (e.g., accelerometers), and output devices (e.g., LEDs, LCD screens) directly onto form prototypes, and author their behavior visually in our software workbench.
The d.tools architecure was inspired by fieldwork conducted at Bay Area design studios and Stanford's graduate product design program. After building an initial prototype with Flash and Phidgets, d.tools has now turned into a full-fledged plug-in for Eclipse with its own dedicated hardware platform. D.tools has been used to re-create existing devices, is currently being deployed at a professional product design consultancy, and will be given to students in Stanford's HCI Design Studio course this winter.
d.tools provides plug-and-play prototyping of hardware components by making each component smart (adding a dedicated microcontroller) and networking the components on a common bus. For graphics display on the small screens commonly found in information appliances, d.tools includes an LCD display which can be connected to a PC graphics card with video output. To facilitate extensibility by advanced users and the software development community at large, d.tools builds on existing open source APIs for its wire protocol (I2C) and the hardware-to-PC interface (OpenSoundControl).
NEW (07/2006): You can now connect the d.tools software environment to other commercially available hardware platforms. Please see the new page on support for Wiring boards, Arduino boards and Phidgets InterfaceKits.
