Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The main study endpoint is to quantify the relative contribution of remote vibrational information in the perception of roughness and hardness. The main study parameter is thus the systematic relationship between the elicited percept (discrimination thresholds of roughness and hardness) and the physical parameters manipulated (i.e., the hurst exponent (roughness) and shore value (hardness) of the stimuli). | — |
Secondary
| Measure | Time frame |
|---|---|
| A second study parameter is the mechanical skin deformation (acceleration variation in time) and the load used during the interactions measured via an accelerometer at the back of the hand and a load cell under the stimuli. | — |
