  1. Explore gaze interaction as an interface to foster increased planning and reflection during computer-based problem solving Tersia //Gowases

  2. Fall Schedule • August-September • Update 8-puzzle • Pre-test • October • Run and document experiment • November-December • Convert experiment document into papers

  3. Preliminary results Time to solution = subjects speed * efficiency of the solution

  4. Preliminary results Dwelltime Time to solution = subjects speed * efficiency of the solution

  5. Degree of seperationfrommechanicalinteraction Touch Gaze-Augmented Dwell-Time (woz) Remote Move arm+hand To directly manipulate screen elements Point with eyes + Press spacebar Point with eyes Say number to be moved Remote user manipulates element Remote user manipulates element

  7. Problem Solving Problem • When interacting with a problem on a computer, users do not plan a sequence of actions. Instead they act as soon as their first actions are decided upon and plan further actions as they go along. Reduce working memory load Insufficient when the number of sub-plans or intermediate increases x
