OpenSense: Validation of IMU-based estimates of kinematics over long durations

Johanna O'Day, Scott Delp, Mazen Al Borno, Vanessa Ibarra, James Dunne, Ajay Seth, Ayman Habib, Carmichael Ong, Jennifer Hicks & Scott Uhlrich
Here we provide the dataset for validation of OpenSense, an open-source toolbox for Inertial-Measurement-Unit-based measurement of lower extremity kinematics over long durations (10 minutes). We computed IMU-based estimates of kinematics using sensor fusion and an inverse kinematics approach with a constrained biomechanical model. We measured kinematics for 11 subjects as they performed two 10-minute trials: (1) walking and turning, and (2) a repeated sequence of varied lower-extremity movements (sitting, standing, stair-climbing, side-stepping, walking, running). Subjects...

Dataset for finger motion and contact by a second finger influence the tactile perception of electrovibration

Yasemin Vardar & Katherine J. Kuchenbecker
Electrovibration holds great potential for creating vivid and realistic haptic sensations on touchscreens. Ideally, a designer should be able to control what users feel independent of the number of fingers they use, the movements they make, and how hard they press. We sought to understand the perception and physics of such interactions by determining the smallest 125 Hz electrovibration voltage that fifteen participants could reliably feel when performing four different touch interactions at two normal...
