The DataBot is a specially modified mouse prototype that communicates three different data properties to the user. For example, it can indicate the size of files, the user-assigned importance or the file’s relative activity (times accessed.) The hardware mod involves the installation of a small servo-motor inside an optical mouse which provides braking action to the mouse’s rollerball, thereby varying the rolling resistance to the user.
DaaBot was developed by Jan Barth and Roman Grasy, two Interaction Design students based in Germany, using Arduino and VVVV.
They’ve also developed a hard drive in a specially designed case which expands and contracts based upon the amount of space used.
