BigEye© is a computer program designed to take realtime video information and convert it into Midi messages. It runs on any PowerPC Macintosh computer running system 8 or later, QuickTime 2.0 and OMS. It supports all QuickTime compatible video digitizers, including serial cameras like the Connectix QuickCam, making it usable for PowerBooks and other non-AV Macintoshes. BigEye also allows you to use prerecorded QuickTime movies as a video input source.

STEIM no longer supports BigEye, and there will be no upgrade to OS X in the near future. We recommend looking into Isadora as an alternative.

Typically achievable frame rates range from 12 frames per second PPC 7100/66 to (the maximum) 25 on an PPC 8500. The user configures the program to extract objects of interest, based on color, brightness and size. These objects are tracked (up to 16 simultaneously) and their position is checked against a user-defined series of 'hot zones'. These 'hot zones' are drawn by the user and are grouped in 'screens'.
Objects and 'hot zones' interact in three distinct ways: a zone sees a new object, a zone sees an old object moving, and a zone sees an object disappear. Each of these three 'events' can generate midi or cause internal program parameters to change. A simple example: the new event causes a note to be switched on, a move event causes a pitchbend and a disappear event causes the note to be switched off.

To specify the Midi to be sent out the program provides for two distinct modes: a simple mode in which the user can specify Midi parameters and screen changes; and a powerful, complete scripting language that includes a real time scheduler, conditionals and loops. In the simpler environment one can quickly link Midi to most of the causing object's parameters, such as position, speed and size. In scripting mode one has many more parameters available. BigEye provides for 16 independent 'channels' which can analyse the incoming image in different ways, allowing, for instance, green objects to act completely differently from objects of other colors.
