  1. Auditory and Visual Feedback duringEye Typing Päivi Majaranta Gaze-Based Interaction Group Tampere Unit for Computer-Human Interaction

  2. TOC • My background (1) • Motivation (2) • Eye typing experiment (6) • Method • Preliminary Results 1

  3. My background HyperLips lipreading tutor Artificial Person GUI tools iDict gaze-assisted translation aid BlissCat symbol communication tutor for language impaired children • Computer-assisted communication & gaze-based interaction  eye typing  • Currently, a Ph.D. studentin Graduate School for User-Centered Information Technology (UCIT) 2

  5. Motivation2 • 20 years of eye typing, mostly “system papers”but typing issues not been studied in detail • e.g. methods for text editing, selection, scrolling, feedback… Päivi Majaranta & Kari-Jouko Räihä, Twenty Years of Eye Typing: Systems and Design Issues, in Proceedings of ETRA2002 • Eye typing provides a rich set of issues for study • from practical point of view: to develop more usable systems • from research point of view: to understand gaze communication task • My Aim is to study the eye typing process in detail and to find ways to make the interaction more efficient and enjoyable 4

  6. SMI iView X RED remote 50 Hz, 0.5-1.0 deg. 13 participants 8 males 5 females Log files + video tape raw, fixation &event data Eye typing experiment - Method1 5

  7. 4 feedback modes Visual only Click + visual Speech + visual Audio only 4 blocks of trials 5 sentences tot. of 1040 phrases entered by the participants Practice Interview & questionnaire Eye typing experiment - Method2 6

  8. Preliminary Results1 • Note: constant dwell time • 900ms for selection (400ms for focus) • Grand mean: 6.97 wpm, • Click+Visual mean: 7.55 wpm 7

  9. Preliminary Results2 Only successfully entered sentences included Error rate vs. KSPC h e l x <del> l o  error rate: 0%  KSPC: 7 / 5 = 1.14 8

  10. Preliminary Results3 • Switching of the point of gaze from keyboard to transcribed text 9

  11. Preliminary Results - Still To Do4 • Types of errors? • E.g. the user did not understand ”focus” ><”selection” • What happened before recalibration? • Initial reaction to the FB, learning • Interview + Questionnaire • e.g. ”Spoken feedback helps, but also irritates” • A lot of interesting minor details to study • e.g. key specific differences (shorter dwell for space?) • Continuation study needed(?) because • Visual & auditory FB not comparable in the current experiment • Visual FB continuous from focus to selection (auditory not) • Audio only FB does not have any hint for focus • Auditory FB only given for selection • Spoken FB time varies (some letters take more time) 10
