Abstract
Grounded force-feedback devices employ diverse
mechanical, electrical, and computational designs, making it
difficult to assess their quality fairly. Device specifications often
have little relation to the opinions experts report during handson
testing. To close this gap, we invited 16 haptics experts
to evaluate four representative devices rendering stiff spheres
while we recorded data with Haptify, our measurement-based
benchmarking system. Our results indicate that expert opinions
of each device’s maximum renderable stiffness correlate with
a performance metric based on measured vibrations. This
approach of pairing expert assessments with external measurements
promises a systematic way to characterize the capabilities
of haptic devices.
