A Laser NonContact BioInstrumental Dobrea Dan Marius System

A Laser Non-Contact Bio-Instrumental Dobrea Dan Marius, System Technical University “Gh. Asachi” Iasi, Romania Working principle ( ) Components: (1) scanner system, (2) video camera and (3) processing unit Working principle: q a laser scanner generates a laser plane at a constant angle from the horizontal plane q the software gets two consecutive images: first, with the laser diode on, with a line of laser light that appears on the target and the second image, with the laser diode off q subtracting these two images we get, as a result, only the laser line projected on the subject’s torso ONE system Evaluation/analysis of Parkinson patients A sensitive computer to the emotional user’s state (by body postures) Clinical features: Tremors of the head Head bent forward Hand tremor MULTIPLE applications From the movement to the emotional state M. I. S. T. E. R. Y. Make It Speak To Everybody ‘Round You (hand sign communication) Some examples Others … ADVANTAGES • the low cost of the system • a non-contact, real-time system • the project’s significant impact on the people’s life • a new kind of information unexploited yet on the HCI systems is used – the emotional state expressed through the body language • possibility to quantitatively/objectively evaluate the Parkinson symptoms Working principle ( ) Laser diode off Laser diode on B [samples] Samples 01 768
