Fazlollahi, F., Seifi, H., Kuchenbecker, K. J., & MacLean, K. E. (2021). "How do expert hapticians evaluate grounded force-feedback devices?" WorldHaptics Conference, Works in Progress, 4 pgs.
The specifications typically reported for grounded force-feedback (GFF) devices do not capture performance quality in a consistent or meaningful way. We designed a study to identify the physical interrogations that expert hapticians employ when evaluating such a device. We report pilot data from one expert who tested three commercial GFF devices in unpowered and powered modes while demonstrating hand motions and describing the interactions. Finally, we outline how we will record expert interactions with a high-resolution apparatus and link measurements with interview data.
