  1. Text Input Under Time Pressure Conditions Liang Jing Department of Computer and Information Sciences University of Tampere, Finland Liang Jing p 01_12 25.02.2003

  2. Text Input Under Time Pressure Conditions Introduction to the Problem • Time pressure conditioning and user performance [1, 9] • Decision making under different time conditions [4, 3] • Decision making and ergonomic aspects of the subjective time [2, 5] Liang Jing p 02_12 25.02.2003

  3. Text Input Under Time Pressure Conditions Background • The time duration of key pressing is one way to allot dual functions on a single key. (mobile phones, themode for input the same character is used in mobile phones • Excessive delay of information sharing will deteriorate the quality of distributed decision making and cause emotional arousal (e.g. annoyance and anger, or lose their patience.) • Working without any delay will lead to stress and increased mental workload to users [10] Liang Jing p 03_12 25.02.2003

  4. Text Input Under Time Pressure Conditions Objectives in General • Research the strategy and features of localization behaviour under time pressure • To study different situations and dynamics of user activity, stipulated by temporal parameters of the computer environment • Designing of techniques for evaluation of user behavior under time pressure conditions • How to reduce the complexity of the decision-making and to save time in urgent conditions Liang Jing p 04_12 25.02.2003

  5. Text Input Under Time Pressure Conditions Research Method • To study different situations and dynamics of user activity, stipulated by temporal parameters of software environment. • Usability evaluation of user activity under different time conditions and communication with computer through typing on virtual keyboard – limited time of a choice per character cyclic text entry (single-button manipulation) – temporal window Liang Jing p 05_12 25.02.2003

  6. Text Input Under Time Pressure Conditions Text Entry Testing Experimental Setup: • Software should provide: virtual keyboard and possibility to control by temporal parameters: waiting time* per character reaction time errors counting • IBM PC • Sound output • Mouse input * http://unipen.nici.kun.nl/7th.iwfhr.2000/proceedings/pdf/poster-001-GarethLoudon.pdf Liang Jing p 06_12 25.02.2003

  7. Text Input Under Time Pressure Conditions Cyclic Synthesis Experimental Setup: • Software should provide: special input techniques through single-button manipulation and possibility to control by temporal parameters: waiting time* per segment reaction time errors counting • IBM PC • Sound output Liang Jing p 07_12 25.02.2003

  8. Text Input Under Time Pressure Conditions Schedule Liang Jing p 08_12 25.02.2003

  9. Cyclic Synthesis Test Entry testing Test Plan Liang Jing p 09_12 25.02.2003

  10. Text Input Under Time Pressure Conditions Expected Results Dynamics for user performance under time pressure conditioning will be evaluated through two techniques and the next parameters: reaction time per character or segment a number of errors Liang Jing p 10_12 25.02.2003

  11. Text Input Under Time Pressure Conditions Prospective applications • Understanding of the phenomenon of changing the subjective time • Typing under time pressure /predictive systems (T9, Dasher) • Time required (difference) between visual response and audio response • Algorithms and methods for detection of individual temporal parameters during designing process of dynamic multimodal interfaces • Adaptive interaction techniques for people with special needs Liang Jing p 11_12 25.02.2003
