An interaction technique encompasses the use of software and hardware to trigger a specific operation in a computer system. Designing a good interaction technique requires knowledge in psychology and physiology of the user in addition to knowledge in computer science and engineering. Formal experiments are often done to validate the efficiency and effectiveness of a proposed interaction technique. This research cluster will focus on the development and formal evaluation of new interaction techniques either using existing hardware or using custom-built hardware.

Research Topics & Projects


Utilizing Screen Edge for Menu Placement

Cell phones have small screens which creates a problem for interface designers. Interfaces currently used for cell phones are inappropriately influenced by interfaces for desktop systems where the screen size is much larger. This research project focused on creating a new user interface control, the Edge Menu , where the menu items are displayed alongside the edges of the screen. A formal experiment has been conducted to evaluate the performance on Edge Menu compared to other types of menus.

AirDisplay: Experimenting with Air Flow as a Communication Media

This project investigated the suitability of air streams to be used alongside personal computers to communicate information. The AirDisplay utilizes the intensity and direction properties of air to exploit the human’s ability to feel mechanical pressure (mechanoreception).

Managing Multiple Phone Calls while Driving

In this project, the interface supports managing multiple phone calls using hand gestures which are performed without raising the hand from the driving wheel. The user can reject, put-on-hold, or merge calls. The Myo arm band is used to capture EMG signals from the muscles and modify the phone status accordingly.

Evaluation of Planar vs. Multi-Planar Hand Gestures in 3D space

One way to classify a gesture is whether it is in the same plane or requires the user to move up and down or sideways in different planes. Comparing

Evaluation of Drag and Drop in 3D Space

Investigate how drag and drop of objects in 3D space using free hand movement could be done efficiently and accurately. The leap motion device is being used to track user hands and conduct formal experiment for this investigation.

Evaluation of Target Selection in 3D Space

Investigate how to select targets in a crowded 3D space using free hand movement. The leap motion device is being used to track user hands and conduct formal experiment for this investigation.

Evaluation of Typing in mid Air

Investigate how to type on a keyboard in mid Air. The leap motion device is being used to track user hands and conduct formal experiment for this investigation. The experiment is evaluating parameters for typing in mid Air, including key size and inter-key spacing.
