Overview
Travel
Getting from one place to another
Wayfinding
Means knowing
Your current location (here) The location of your destination (there) A (partial) route for getting there from here
These are related, but are really two
large separate problems

Travel: Key Research Problems
Limited physical space, possibly infinite virtual
space
Think Holodeck
Different types of travel
Walking, running, turning, side stepping, back
stepping, crawling, quick start/stop, ...
Need to do other things while traveling
Usually, travel is not the goal of your current task
It is very easy to get (cognitively) lost in virtual
reality
R.W. Lindeman - WPI Dept. of Computer Science 4
Support for General Walking
Multi-sensory cues
Visual Auditory Tactile Kinesthetic Vestibular Cognitive
Each technique used for travel has more
- r less support for each of these

Overview of Travel Approaches
Gestural
Hand Head Foot (walking in place) Body (real walking, re-directed walking)
Device
Hand-held devices (joystick, gamepad, 2D
mouse)
Platforms
Passive (tilt, pressure, VirtuSphere) Active (treadmills, steppers, CirculaFloor)

Gestures for Travel
Hand typically... Head...
R.W. Lindeman - WPI Dept. of Computer Science 7
Gestures (cont.)
Walking in place (Gaiter [Templeman])
Forward/backward/side-step gestures Go prone, run, small real steps
R.W. Lindeman - WPI Dept. of Computer Science 8
Gestures (cont.)
Redirected walking (UNC-CH)
