Exploring human multi-channels perceptional characteristics is an important research field in physical psychology. This study innovatively designed a visual-tactile dot-matrix stimulator, as an experimental device for physical psychologist to analyze human perception. The device includes a host control platform, a sub-control module, a visual dot-matrix display module, a tactile dot-matrix display module, etc. The host control platform produces the visual-tactile instructions, and the sub-control module executes these instructions. The visual dot-matrix display module provides visual perception. It consists of 19 rows and 12 columns of 228 inch LED lamp arrays with 85 Hz refresh rate and 10 gray-value grades (7.6–75.8 lux). And the minimum package size of an LED lamp is 1.0×0.5 mm with alternative colors of red, white, yellow, and green. The tactile dot-matrix display module provides haptic perception by 6 rows of 4 columns of 24 contact arrays. Each contact has 1.5 mm diameter with 0.40 ±0.05 mm bump height and 10 Hz refresh rate. In the self-locking position case, the contact can endure 10 N force. The experimental results show that this stimulator can independently or combined control any LED lamps and contacts to provide the visual-tactile stimuli. This function shall satisfy for physical psychologist to acquire quantitative experimental data for analyzing human perception. This stimulator also has compact (70×66×80 mm volume), light (337 g), and mobile (15 m work distance) advantages.
