    An Evaluation of Radar Metaphors for Providing Directional Stimuli Using Non-Verbal Sound

    We compared four audio-based radar metaphors for providing directional stimuli to users of AR headsets. The metaphors are clock face, compass, white noise, and scale. Each metaphor, or method, signals the movement of a virtual arm in a radar sweep. In a user study, statistically significant differences were observed for accuracy and response time. Beat-based methods (clock face, compass) elicited responses biased to the left of the stimulus location, and non-beat-based methods (white noise, scale) produced responses biased to the right of the stimulus location. The beat methods were more accurate than the non-beat methods. However, the non-beat methods elicited quicker responses. We also discuss how response accuracy varies along the radar sweep between methods. These observations contribute design insights for non-verbal, nonvisual directional prompting

    “Smart home system is like a mother”: The potential and risks of using product metaphors to influence consumers’ comprehension of really new products

    Driven by innovative technology, really new products (RNPs) incorporate new functions that provide significant benefits for consumers. But consumers often experience difficulty understanding RNPs, which hinders consumers’ further adoption. To facilitate consumers’ comprehension, the use of product metaphors in RNPs is a promising strategy because it relates a target RNP to a source product/concept familiar to consumers. By using knowledge from the familiar source, consumers could gain better comprehension of the RNP. However, product metaphors can also carry risks that hinder consumers’ comprehension of RNPs, such as consumers’ misidentification of the source and consumer’ inability to use the relevant knowledge to comprehend RNPs. This research investigates the potential and risks of using product metaphors in RNPs through a mixed-methods approach. Specifically, an experiment and in-depth interviews were conducted to examine the effects of product metaphors on consumers’ comprehension. Results revealed that consumers encounter difficulty in detecting the similarities between source concepts/products and target RNPs due to which product metaphors may not necessarily enhance consumers’ comprehension. Accompanying a product metaphor with a textual clue can help consumers to detect the similarities between source concepts/products and target RNPs, leading to enhanced consumers’ comprehension. Implications for theory and practice are discussed. <br

    The Shape of Poetry: A Typographic Exploration of Poetry and Synesthesia

    Get PDF
    The Shape of Poetry is a thesis which explores the relationships of synesthesia, typography and poetry. Synesthesia is a neurologically-based condition in which stimulation of one sensory or cognitive pathway leads to automatic, involuntary experiences in a second sensory or cognitive pathway. This phenomenon is common in poetry as a rhetorical device. In graphic design, we uses typography and other visual elements to make cross-sensory metaphors as well. The similarity among these three provides a new field of research possibilities. The goal of the thesis is to visualize poetry by exploring typographic variations and implementing synesthesia findings. The final result is a campaign to promote William Shakespeare’s sonnets, in both print and digital applications. Overall the findings of this thesis aim at giving designers another angle when designing for multi-media platforms, and inspire those who have the similar interests in the relationship of sensory perception and design

    Tactile Displays for Pedestrian Navigation

    Existing pedestrian navigation systems are mainly visual-based, sometimes with an addition of audio guidance. However, previous research has reported that visual-based navigation systems require a high level of cognitive efforts, contributing to errors and delays. Furthermore, in many situations a person’s visual and auditory channels may be compromised due to environmental factors or may be occupied by other important tasks. Some research has suggested that the tactile sense can effectively be used for interfaces to support navigation tasks. However, many fundamental design and usability issues with pedestrian tactile navigation displays are yet to be investigated. This dissertation investigates human-computer interaction aspects associated with the design of tactile pedestrian navigation systems. More specifically, it addresses the following questions: What may be appropriate forms of wearable devices? What types of spatial information should such systems provide to pedestrians? How do people use spatial information for different navigation purposes? How can we effectively represent such information via tactile stimuli? And how do tactile navigation systems perform? A series of empirical studies was carried out to (1) investigate the effects of tactile signal properties and manipulation on the human perception of spatial data, (2) find out the effective form of wearable displays for navigation tasks, and (3) explore a number of potential tactile representation techniques for spatial data, specifically representing directions and landmarks. Questionnaires and interviews were used to gather information on the use of landmarks amongst people navigating urban environments for different purposes. Analysis of the results of these studies provided implications for the design of tactile pedestrian navigation systems, which we incorporated in a prototype. Finally, field trials were carried out to evaluate the design and address usability issues and performance-related benefits and challenges. The thesis develops an understanding of how to represent spatial information via the tactile channel and provides suggestions for the design and implementation of tactile pedestrian navigation systems. In addition, the thesis classifies the use of various types of landmarks for different navigation purposes. These contributions are developed throughout the thesis building upon an integrated series of empirical studies.EThOS - Electronic Theses Online ServiceGBUnited Kingdo

    Advances in Human-Robot Interaction

    Rapid advances in the field of robotics have made it possible to use robots not just in industrial automation but also in entertainment, rehabilitation, and home service. Since robots will likely affect many aspects of human existence, fundamental questions of human-robot interaction must be formulated and, if at all possible, resolved. Some of these questions are addressed in this collection of papers by leading HRI researchers
