GUIDe: Alternative to the Computer Mouse

Group 8

Paul McNutt, Blake Williams, Colby Holland, and Brandon Carpenter

key terms
Key Terms
  • GUIDe (Gaze-enhanced User Interface Design)
    • allows a user to perform without a mouse virtually every input function possible when utilizing a mouse
  • EyePoint
    • software that works alongside standard eye tracking hardware that allows a user to look at a web link
key terms3
Key Terms
  • Algorithm
    • a precise rule (or set of rules) specifying how to solve some problem 
  • Scrolling Threshold
    • the upper 1/3 and lower 1/3 of a GUIDe enabled monitor that when gazed upon causes the browser to scroll either direction.
evolution of eye tracking capabilities

Evolution of Eye Tracking Capabilities

Problems and Solutions to an Exciting New Technology

problems
Problems
  • The use of the product was designed for people with certain needs and disabilities.
  • Tracking eye movement is based on a camera picture of the pupil which is not a constant motion.
  • COST!
solutions
Solutions
  • With practice, just like with the mouse, a skilled user can actually save time with the use of the GUIDe system.
  • With time all technology gets better. With the algorithm written by Kumar and higher speed and resolution cameras this problem will eventually solve itself.
  • As the use of the software becomes more commonplace and widely accepted the costs comedown and become much more managable.

The GUIDe Software

WHAT IS IT AND HOW DOES IT WORK?

history of guide
History of GUIDe
  • GUIDe is being developed by researchers at Stanford University.
  • This is an example of pull technology. It was developed for use with people who have disabilities. It can help them overcome obstacles of these disabilities, better their life, and quite possibly allow them to be in the work force at a higher competency.
guide
GUIDe
  • The GUIDe approach to eye tracking solutions is systematic.
    • It is comprised of hardware and software working simultaneously to perform its tasks.
  • The Hardware
    • Infrared camera and a special monitor
  • The Software
    • GUIDe is a comprisal of many programs much like Office that helps it to perform its duties.
application areas
Application Areas
  • Pointing and Selection
  • Application Switching
  • Scrolling and Panning
  • Security and Utilities
pointing and selecting
Pointing and Selecting
  • EyePoint™ software allows users to perform basic mouse operation by using a combination of gaze and hotkeys.
    • It reduces / eliminates the dependency on the mouse for most everyday tasks such as surfing the web
using eyepoint
Using EyePoint
  • LOOK at the desired target.
using eyepoint13
Using EyePoint
  • PRESS and hold the hotkey
using eyepoint14
Using EyePoint
  • LOOK at target in magnified view
using eyepoint15
Using EyePoint
  • RELEASE hotkey/trigger
application switching
Application Switching
  • EyeExposé™ allows for gaze-based application switching combining the ease of use of an Apple “Exposé-like” application switching with gaze-based selection.
using eyeexpos
Using EyeExposé™
  • Current active window
using eyeexpos18
Using EyeExposé™
  • PRESS and hold the hotkey
using eyeexpos19
Using EyeExposé™
  • LOOK at the target window
using eyeexpos20
Using EyeExposé™
  • RELEASE the hotkey/trigger
panning and scrolling
Panning and Scrolling
  • EyeScroll™ allow for automatic, adaptive scrolling on content being viewed on the screen.
  • EyeScroll supports multiple scrolling modes depending on the user's preference and reading style.
security and utilities
Security and Utilities
  • EyePassword™ allows gaze-based password/pin entry. It prevents shoulder surfing and does not generate any keyboard and mouse events making it more difficult to use standard event loggers.
  • EyeSaver™ turns on the screen saver when a user looks away from the screen and automatically turns off the screensaver when the user looks back at the screen.

summary
Summary
  • Promising new technology.
  • GUIDe can help people overcome disabilities.
  • GUIDe has many obstacles to overcome.
  • We could see this software available sooner than we think!
