Precise, repeatable measurement of vibrotactile feedback
Grewus
New technology from Grewus makes it possible to quantify vibrotactile feedback for the first time. Two acceleration sensors measure haptic events for this purpose. The company’s artificial finger (ArFi) collects data necessary for the description of haptic feedback. Among other things, it measures acceleration values under the influence of force, latency and trigger thresholds.
Haptics includes acoustics, so acoustic parameters are collected in parallel. An intuitive GUI facilitates operation. The measurement results are conveniently evaluated with the analysis software.
The data in the time and frequency domain is displayed, along with the calculation of the GHIV Grewus Haptic Intensity Value (haptic perception). In this way, active haptics is optimized and made quantifiable during development.
