User goals
Move along in a predetermined direction without a joystick or controller
Interaction
- User uses the gaze cursor for targeting
- They do not have a joystick or any controller to move around the virtual space
- The space has been designed to allow full interaction using only gaze
- The user moves the gaze cursor onto directional arrows on the floor. The arrow indicates the direction of travel.
- The cursor triggers the arrow to move forwards and this pulls the user along for so long as their gaze remains fixed on the arrow
- Looking away from the arrow stops the movement
- The gaze essentially behaves like an invisible grappling hook that locks onto the moving arrow
Good
- Allows the user to move along without a controller
- Allows user to control distance moved, and stop movement when desired
Bad
- Can only travel in predetermined directions and predetermined distances
- The user needs to first see the arrow and understand they must fixate the cursor onto it
- The fusing duration needs to be engineered correctly (too soon and results in accidental activation, too long and user may fail to discover it)
