Color choice as a function of waveform and force-feedback vibration

This scientific investigation highlights the relationship between visual stimulus sinusoidal spatial frequency, force-feedback (FF) square, triangle, and sinusoidal wave driven vibrational periodicities, and their association with the visible light spectrum colors red, orange, yellow green, blue indigo, and violet. A customized FF joystick program presented randomly ordered .01, .015, .03, .045, and .09 seconds-per-cycle period FF vibrations while soliciting participant color-choice. Each vibration was randomly presented 10 times across 50 trials. Analyses indicate significant but differing color-association preferences for square, triangle, and sine waveform driven vibrations.
