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

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)
