Reality Satellite Multimedia Peripheral

The Reality Satellite is the first truly versatile multimedia product. The Reality Satellite can act as a peripheral to the PC or as a standalone exhibit controller. It provides surround sound with audio input selection, sound level sensor for Kiosk sound control, light level sensor for proximity sensing, serial, MIDI and network ports for interfacing to other peripherals and IR remote control. A software handler package interfaces the PC/MAC to the Reality Satellite. This hardware is used in the Environmental Ambience systems.

 

Nerf® Sensing Screen Controller

The Nerf® Sensing Controller analyzes vibration data from four piezoelectric sensors mounted on a thin mylar film. The mylar film was stretched over a project screen that comprises the Nerf® Sensing Screen, The Nerf® Sensing Screen was the first interactive sensing system for determining where and how hard Nerf™ projectiles strike a video screen.

 

Ultrasonic Controller

The Ultrasonic Controller is a microcontroller based ultrasonic sensing system. It incorporates a Motorola MC68HC12 microcontroller and a Polaroid sensor and circuit board. The Ultrasonic Controller connect to the PC through a USB or serial port to be incorporated into a sensing system. The components are mounted in a transparent VHS videotape case.

 

Digital Audio Signal Processor (1989)

In the early days of digital audio, high quality 16-bit samplers were unavailable. This 16-bit signal processor utilized a 12.5 mhz Motorola MC68000 microprocessor, 16-bit ADC (analog to digital converter), 16-bit DAC (digital to analog converter), input and output low pass filters, and a high accuracy input sample and hold.
