Smart Seat / 2003 / Human Communication Technologies Lab, University of British Columbia

Process: A research project carried out for Nissan Motor company while I was working at the Human Communication Technologies lab.


The scope of the project was to improve a persons perception of their driving environment by augmenting their visual information with haptic informantion.


Early on different methods for communicating surrounding traffic through the sense of touch were explored. By having actuators in the car seat which apply pressure to a drivers leg and back corresponding to the location of cars surrounding the car, drivers would know where other cars were around their vehicle. Different types of actuators were tested and different numbers of actuators were tested.


eventually a simulated driving environment was set up to test the perceptual salience of the concept.
Skills: PC motor control using Comedi DAQ board library for Linux. I also programmed a simple OpenGL world of a road with a car passing by the driver.


Team:
Afshin Mehin - electroemechanical prototype with simple early CG development, Dylan Passmore, more developed CG environment for perceptual testing. Sidney Fels research supervisor.



work in process

a chair with manual actuators was prototyped

air bladders were tested

motor control version 1

motor control version 2

A manual actuation test rig was created to easily understand the psychology of matter

the actuators had sensors to measure the force people were feeling.

testing with a subject

testers were following random force curves.
