G-coder^TM sensor technology

For detecting the movements of the ball joint of the simball joystick we developed a new sensor technology; G-coder sensors.

G-coder sensor enables true non-contact 3D measuring of movements and deformations of an object with only one sensor. The technology is "machine vision" based and has been developed and patented by G-coder Systems AB since 2005.

The unique elements;

• A dot pattern which is laser marked in the surface of the moving body
• Advanced analysis of the images from an optical sensor

G-coder sensor technology therefore offers:

• Absolute measurement, no calibration is needed
• Ability to detect movements also on non-plane surfaces like shafts and spheres; for example the ball joint sphere in simball joysticks
• High resolution; 1-3 micrometer with the current HW/SW platform
• Easy to embed
• Includes few moving parts
• Cost and size effective
