Abstract

An electronic data collection device configured in a substantially two-dimensional arrangement is disclosed. The data collection device uses inexpensive flexible sheet materials to provide a flat framework in which to situate an interconnected combination of electronic components. The components provide an interactive function to supply input-output, control, and power functions. Components can include an information display, switches for responding to questions displayed on the information display, memory for storing responses to the questions, and a controller for controlling the operation of the data collection device. In addition, the device is provided with a data transfer interface that permits stored responses to be gathered by a response data accumulation device, such as a computer, having a corresponding interface.
