Research topics

Augmenting Around-Device Interaction
Prototyping, developing, and empirical research

  • The utilization of various built-in sensors for providing alternative ways of interacting with a mobile device.

Predicitve evaluation of touchscreen interaction efficiency
Modeling & empirical research

  • Towards a TLM (Touch-Level Model), on the KLM (Keystroke-Level Model) basis.

Predicting text entry speeds for various input methods
Modeling & empirical research

  • Integrating language models (digraph probabilities) and diverse movement models (Fitts' law and/or others).

Novel text entry methods for (touchscreen) mobile devices
Modeling & empirical research; assistive technologies

  • Text entry using novel and/or alternative modalities (tilt, scan) and/or new keyboard layouts; Around-Device Interaction (ADI) applied to sensor-based text entry.

Sampling representative phrase sets for text entry empirical research
Sampling procedure design and development

  • Extracting phrase set candidates from available text corpora, and searching for a sample with near-optimum representativeness of the target language.

Integrating Blink Click interaction into a head tracking system
Empirical research: Usability testing

  • Proposing a novel version of Blink Click (BC) action, initiated by end user eye blinking, as a valuable supplement for faster mouse click emulation. Quantitative and qualitative comparison with well-known Dwell Click (DC) approach.
