Earlier this week I wrote about a paper that was accepted to the Frontiers in Education (FIE) 2017 conference, but the fact is that yet another paper which I co-authored was accepted to another conference, Sound and Music Computing (SMC) 2017, earlier in May! Emma Frid (lead author), Roberto Bresin and Eva-Lotta Sallnäs Pysander from the department of Media technology and Interaction Design at the Royal Institute of Technology (KTH) are the other authors on that paper. The title of the SMC paper is “AN EXPLORATORY STUDY ON THE EFFECT OF AUDITORY FEEDBACK ON GAZE BEHAVIOR IN A VIRTUAL THROWING TASK WITH AND WITHOUT HAPTIC FEEDBACK”.
The paper is based on a small part of an extensive study, focusing on the effect of haptic and audio feedback on perception of object qualities and visual focus, performed a few years ago. In this particular paper we use eye-tracking metrics to investigate if auditory feedback in particular affects gaze behaviour in an environment where the task is to pick up a ball and throw it into a target area. We looked at both the effect of sound in general and effects of different sound models. Like in many other studies we have been involved in, conditions with different modality combinations were compared against each other. I will write more about the results when the paper has been presented and there is a link to the published proceedings. Search for the title given above if you want to find the specific session and listen to Emma’s presentation at the conference!
Here is the abstract, summarizing the main points:
This paper presents ﬁndings from an exploratory study on the effect of auditory feedback on gaze behavior. A total of 20 participants took part in an experiment where the task was to throw a virtual ball into a goal in different conditions: visual only, audiovisual, visuohaptic and audiovisuohaptic. Two different sound models were compared in the audio conditions. Analysis of eye tracking metrics indicated large inter-subject variability; difference between subjects was greater than difference between feedback conditions. No signiﬁcant effect of condition could be observed, but clusters of similar behaviors were identiﬁed. Some of the participants’ gaze behaviors appeared to have been affected by the presence of auditory feedback, but the effect of sound model was not consistent across subjects. We discuss individual behaviors and illustrate gaze behavior through soniﬁcation of gaze trajectories. Findings from this study raise intriguing questions that motivate future large-scale studies on the effect of auditory feedback on gaze behavior.
As was the case with the FIE paper mentioned earlier, the SMC paper is just presenting a small part of a large study, so there is definitely a lot more to tell about the study and the different parameters measured. I will return to the overall study as soon as more papers are out! 🙂
