SqueezeOrb: A Low-Cost Pressure-Sensitive User Input Device

By Thomas Pintaric, Thomas Kment, and Wolfgang Spreicer


This paper introduces a new low-cost pressure-sensitive user input device called "SqueezeOrb". The device is built from an assembly force-sensing resistors embedded in an elastic hand exerciser. A USB-enabled microcontroller continuously samples the sensors, applies a double-exponential noise-reduction filter and streams the resulting "handgrip strength" measurement to an attached host computer at a frequency of up to 1000 Hz. When combined with optical motion-tracking, the SqueezeOrb becomes a pressure-sensing input device for three dimensional interaction.
