ArgusEyes: Interactions by Combining Multiple Modules with Optical Flow Sensors.

We propose ArgusEyes, which realizes various interactions by simply combining compact modules equipped with optical flow sensors. Each ArgusEyes module comprises three core components: a printed circuit board (PCB), a lens, and a case. It accurately acquires the amount of movement of the contacting surface. This system excels at precise surface movement detection, with a validation demonstrating a maximum difference of 2.50 mm between minimum and maximum movement values. We present three illustrative examples of applications that use ArgusEyes to demonstrate its versatility (Figure 1). Examples of applications include force measurement, bar-shaped input devices, and Interaction with a soft cloth.
