Study: Point Estimation

[Note: We are no longer recruiting paid participants for this study] We are running a series of studies (during the months of May and June 2014) to evaluate of a number of sonic interaction techniques that we designed to help with non-visual point estimation tasks. We often perform point estimation tasks when, for example, we look at a graph or a chart and estimate values based on the visual representations available, such as bars’ length in a bar chart or points’ position on a line graph.

We have developed a number of ways to display points’ positions on a plane using audio only, and we would like to test how efficient these techniques are.

If you choose to participate in this study you will be expected to attend a session, which last 30 minutes at Queen Mary University of London. You will be given a short training to familiarise yourself with the interface that you will be using. Once you feel comfortable using it, you will be shown a series of points at different positions on the screen and you will be asked to reproduce their position using an audio-only interface. You will also be asked to fill a number of questionnaires throughout the session to tell us about yourself and your experience using the interface.

As part of this study, we will log your interaction with the system and may video record you as you use it. All records will be anonymised. You will receive a payment of £10 for your participation in this study.
