The touch feeling can be split into several different impressions. Assigned to these impressions are descriptors which were determined in numerous tests with subjects. They are split in vertical, tangential and stationary movements when touch objects.
Testing description:
- The reference system consists of 10 plates with 55 different samples/specimens.
- Assigned to every descriptor are several samples, which are numbered.
- By comparing the touch feeling between the test object and samples/specimens, a number can be determined for the descriptor.
- All numbeers taken together form the haptic fingerprint.
- Included in the supply is an Excel spreadsheet in which the touch data can be entered.
- A fingerprint in the form of a spider chart is then generated automatically.
