Effects of Sound Type on Recreating the Trajectory of a Moving Source
by G. Wilson, S. Brewster, H. Caltenco, C. Magnusson, S. Finocchietti, G. Baud-Bovy and M. Gori
This work-in-progress paper from the ABBI project will be presented as a poster at CHI ’15.
The ABBI (Audio Bracelet for Blind Interaction) device is designed for visually impaired and blind children to wear on the wrist and produce sound based on the movement of the arm through space. The primary function is to inform a child (or adult) about his/her own movements to aid spatial cognition rehabilitation. However, the device could also be worn by friends and family and be used to inform the visually impaired person of others’ movement in the environment. In this paper, we describe an initial experiment that measured how well blindfolded sighted individuals could track a moving sound source in 2D horizontal space and then walk the same route to the same end position. Six sounds, including natural sounds, abstract sounds, Earcons and speech, were compared to identify which type of sound produced more accurate route recreation.
A Dose of Reality: Overcoming Usability Challenges in VR Head-Mounted Displays
by Mark McGill, Daniel Boland, Roderick Murray-Smith and Stephen Brewster
We identify usability challenges facing consumers adopting Virtual Reality (VR) head-mounted displays (HMDs) in a survey of 108 VR HMD users. Users reported significant issues in interacting with, and being aware of their real-world context when using a HMD. Building upon existing work on blending real and virtual environments, we performed three design studies to address these usability concerns. In a typing study, we show that augmenting VR with a view of reality significantly corrected the performance impairment of typing in VR. We then investigated how much reality should be incorporated and when, so as to preserve users’ sense of presence in VR. For interaction with objects and peripherals, we found that selectively presenting reality as users engaged with it was optimal in terms of performance and users’ sense of presence. Finally, we investigated how this selective, engagement-dependent approach could be applied in social environments, to support the user’s awareness of the proximity and presence of others.
To Beep or Not to Beep? Comparing Abstract versus Language-based Multimodal Driver Displays
by Ioannis Politis, Stephen Brewster and Frank Pollick
Multimodal displays are increasingly being utilized as driver warnings. Abstract warnings, without any semantic association to the signified event, and language-based warnings are examples of such displays. This paper presents a first comparison between these two types, across all combinations of audio, visual and tactile modalities. Speech, text and Speech Tactons (a novel form of tactile warnings synchronous to speech) were compared to abstract pulses in two experiments. Results showed that recognition times of warning urgency during a non-critical driving situation were shorter for abstract warnings, highly urgent warnings and warnings including visual feedback. Response times during a critical situation were shorter for warnings including audio. We therefore suggest abstract visual feedback when informing drivers during a non-critical situation and audio in a highly critical one. Language-based warnings during a critical situation performed equally well as abstract ones, so they are suggested as less annoying vehicle alerts.
In the Heat of the Moment: Subjective Interpretations of Thermal Feedback During Interaction
by Graham Wilson, Gavin Davidson and Stephen Brewster
Thermal feedback can be an engaging and convincing means of conveying information, but its meaning in interaction can be ambiguous, so interface designers may not be sure how users naïvely interpret thermal feedback during interaction. The research in this paper measured subjective interpretations of thermal stimuli in four different scenarios: social media activity, a colleague’s presence, the extent of use of digital content and restaurant experiences and provides guidelines for the design of thermal feedback are presented to help others create effective thermal interfaces.
Research has shown that thermal feedback can be an engaging and convincing means of conveying experimenter-predefined meanings, e.g., material properties or message types. However, thermal perception is subjective and its meaning in interaction can be ambiguous. Interface designers may not be sure how users could naïvely interpret thermal feedback during interaction. Little is also known about how users would choose thermal cues to convey their own meanings. The research in this paper tested subjective interpretations of thermal stimuli in three different scenarios: social media activity, a colleague’s presence and the extent of use of digital content. Participants were also asked to assign their own thermal stimuli to personal experiences, to help us understand what kinds of stimuli people associate with different meanings. The results showed strong agreement among participants concerning what warmth (presence, activity, quality) and cool mean (absence, poor quality). Guidelines for the design of thermal feedback are presented to help others create effective thermal interfaces.
We have had three full papers accepted for CHI ’15 in Seoul, Korea! Mark’s looks at techniques for brining reality into virtual reality, Graham’s describes a series of experiments on thermal output and Ioannis’ is about in-car multimodal notifications. Graham also has a WiP on recreating the trajectories of moving sound sources for ABBI. See you in Seoul!
