WHY REDESIGN?

1 Never before tested by or on anyone besides

the developers

Users don’t necessarily know what they need!

PROTOTYPE


BUTTON FUNCTIONALITY

LESS BUTTONSUsers confused by unnecessary buttons

“Middle button should already be assigned to operations or functions already in the interface” - ABOUT FACE 2.0: Interaction Design, P272

FUNCTIONS◦ menu button → pop up menu

◦ right button → click and drag

◦ left button → selecting menu options

◦ trigger → fly/zoom

◦ joystick → angle of view/perspectiveWednesday, July 10, 13

REPLACE SCROLL WHEEL WITH JOYSTICK

PROBLEM:Changing perspective and navigating at

the same time

JOYSTICK ENABLES:◦ "head-like" movement

◦ paradigm of flight

◦ movement in multiple directions (ie. panoramic view)

◦ adjustable, precise sensitivity to motion

◦ easy switching between menus


NESTED JOYSTICK

PROBLEM:Unintentional bumping of center scroll

JOYSTICK ENABLES:◦ Nesting- acts as a guard ◦ positioned at the same level as

the buttons for easy thumb use


JOYSTICK SHOULD SEPARATE THE TWO BUTTONS

PROBLEM:User frequently misclicks

JOYSTICK ENABLES:◦ Distinguishes left and right

mouse buttons◦ Control will be through

joystick


JOYSTICK SHOULD BE AT THE BASE OF BUTTONS

PROBLEM:•Users commented that scroll wheel was too high•Difficult to reach with thumb

JOYSTICK ENABLES:joystick will be same level as both

mouse buttons, making it easier for

users to reach reducing amt of

buttons


ENABLED CONTROLS LIGHT UP

LIGHTING UP ENABLED CONTROLS NOTIFIES THE USER

VISIBILITY OF SYSTEM STATUS

RECOGNITION RATHER THAN RECALL

Functions enabledType of environmentHow to navigate through the environment

The system should always keep users informed about what is going on.

Minimize the user's memory load by making objects, actions, and

options visible.


GROOVESAN ERGONOMIC IMPLEMENTATION

PURPOSE OF GROOVES

ComfortStabilityCorrect upright placement


GRIPSAN ERGONOMIC IMPLEMENTATION

PURPOSE OF GROOVES

• "Universal" CAVE controller

◦ Create grooves for left- handedand right-handed users

◦ Reduce risk of dropping and damaging controller


EMPLOYING CLICK AND DRAG MOTION GESTURES

• Users preferred:

◦ A more natural motion gesture for navigation■ Implement a more natural,

consistent, and easy- to-learn gesture

◦ Clicking and dragging gesture instead of scrolling■ Intuitive, familiar, and reliable

(Charade)■ Avoids fatigue due to less effort


FUTURE GOALS

CREATE AND TEST

A REAL 3D PROTOTYPE

INTRODUCTORY TUTORIAL


FINAL THOUGHTS

DOES IT DESERVE TO EXIST?

DOES IT MAKE LIFE BETTER?
