GUIDe: Alternative to the Computer Mouse

1
GUIDe Alternative to the Computer Mouse

• Group 8
• Paul McNutt, Blake Williams, Colby Holland, and
  Brandon Carpenter

2
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

3
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.

4
Evolution of Eye Tracking Capabilities

• Problems and Solutions to an Exciting New
  Technology

5
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!

6
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?

8
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.

9
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.

10
Application Areas

• Pointing and Selection
• Application Switching
• Scrolling and Panning
• Security and Utilities

11
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

12
Using EyePoint

• LOOK at the desired target.

13
Using EyePoint

• PRESS and hold the hotkey

14
Using EyePoint

• LOOK at target in magnified view

15
Using EyePoint

• RELEASE hotkey/trigger

16
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.

17
Using EyeExposé

• Current active window

18
Using EyeExposé

• PRESS and hold the hotkey

19
Using EyeExposé

• LOOK at the target window

20
Using EyeExposé

• RELEASE the hotkey/trigger

21
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.

22
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.

23
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!

24
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.

25
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!
