HCI research

Based on our work with 3D interactive content, we are also exploring how different input devices can be effectively used under different conditions. We have also developed new interactive user interfaces that can capture complex feedback in online surveys and can make usability and other types of evaluations more engaging for participants.

Evaluating and improving usability

While developing 3D volumetric visualizations, we saw a need to further test the performance and usability of input devices that should be both precise and easy to learn. In our user studies, we aim to test both the performance and usability aspects of input devices on diverse groups of participants to make sure the devices are reliable enough for real-world usage.

Our user studies usually include usability evaluations based on the standardized SUS questionnaire that can be tedious for participants to complete. For this reason we also started developing new interactive user interfaces for online surveys that are more engaging and can also better capture complex feedback, like the one needed in our mood and music research. Preliminary research has shown positive results in terms of perceived time and validity of results, and we are now working on open sourcing an extendable version of the Stripe interface that could be reused in a wide range of online surveys.
