On the Design of Personal Digital Bodyguards: Impact of Hardware Resolution on Handwriting Analysis
Daniel Martín-Albo, Luis A. Leiva, Réjean Plamondon · 2016
Handheld touch-capable devices have become one of the most popular and fastest growing consumer products. It seems logical therefore to think of such devices as Personal Digital Bodyguards (PDBs) in charge for example of biometrical, biomedical, and neurocognitive monitoring by just inspecting the user's handwriting activity. However, it is unclear whether the hardware of today's devices is capable to handle this task. To this end, we conducted a comparative study regarding the capabilities of past and current tablets to allow for the design of PDBs based on the exploitation of the Kinematic Theory. Our study shows that, while some improvements are still necessary at the sampling frequency level, the conclusions drawn by the Kinematic Theory can be directly transferred to PDBs.
