The Hide and Seek of Workspace: Towards Human-Centric Sustainable Architecture

論文URL: http://dl.acm.org/citation.cfm?doid=3173574.3173649

論文アブストラクト: This contribution exemplifies how the study of space perception and its impact on space-use behavior can inform sustainable architecture. We describe our attempt to integrate the methods of user research in an architectural project that was focused on optimization of space usage. In an office building, two large office rooms were refurbished to provide desk-sharing opportunities through hot-desking. We studied the space-use behavior of 33 office workers over eight weeks in those two rooms as well as their occasional presence in ten other areas (cafeteria, atrium, meeting rooms, etc.). Quantitative and qualitative analyses were performed to understand the nature and nuances of space occupancy at the scope of the building and within the refurbished offices. While at the scope of building the patterns of movements between rooms were found to be related to the professional profile of the users, at the scope of office the occupancy patterns were influenced by the spatial design of workspaces. More precisely, certain visual attributes of a workspace, namely Visual Exposure and Visual Openness, could determine whether or not it was regularly used. In this paper, we describe our findings in detail and discuss their implications for sustainable building design.

Voicesetting: Voice Authoring UIs for Improved Expressivity in Augmentative Communication

論文URL: http://dl.acm.org/citation.cfm?doid=3173574.3173857

論文アブストラクト: Alternative and augmentative communication (AAC) systems used by people with speech disabilities rely on text-to-speech (TTS) engines for synthesizing speech. Advances in TTS systems allowing for the rendering of speech with a range of emotions have yet to be incorporated into AAC systems, leaving AAC users with speech that is mostly devoid of emotion and expressivity. In this work, we describe voicesetting as the process of authoring the speech properties of text. We present the design and evaluation of two voicesetting user interfaces: the Expressive Keyboard, designed for rapid addition of expressivity to speech, and the Voicesetting Editor, designed for more careful crafting of the way text should be spoken. We evaluated the perceived output quality, requisite effort, and usability of both interfaces; the concept of voicesetting and our interfaces were highly valued by end-users as an enhancement to communication quality. We close by discussing design insights from our evaluations.

It's a Wrap: Mapping On-Skin Input to Off-Skin Displays

論文URL: http://dl.acm.org/citation.cfm?doid=3173574.3174138

論文アブストラクト: Advances in sensing technologies allow for using the forearm as a touch surface to give input to off-skin displays. However, it is unclear how users perceive the mapping between an on-skin input area and an off-skin display area. We empirically describe such mappings to improve on-skin interaction. We collected discrete and continuous touch data in a study where participants mapped display content from an AR headset, a smartwatch, and a desktop display to their forearm. We model those mappings and estimate input accuracy from the spreads of touch data. Subsequently, we show how to use the models for designing touch surfaces to the forearm for a given display area, input type, and touch resolution.

Breeze: Sharing Biofeedback through Wearable Technologies

論文URL: http://dl.acm.org/citation.cfm?doid=3173574.3174219

論文アブストラクト: Digitally presenting physiological signals as biofeedback to users raises awareness of both body and mind. This paper describes the effectiveness of conveying a physiological signal often overlooked for communication: breathing. We present the design and development of digital breathing patterns and their evaluation along three output modalities: visual, audio, and haptic. We also present Breeze, a wearable pendant placed around the neck that measures breathing and sends biofeedback in real-time. We evaluated how the breathing patterns were interpreted in a fixed environment and gathered qualitative data on the wearable device's design. We found that participants intentionally modified their own breathing to match the biofeedback, as a technique for understanding the underlying emotion. Our results describe how the features of the breathing patterns and the feedback modalities influenced participants' perception. We include guidelines and suggested use cases, such as Breeze being used by loved ones to increase connectedness and empathy.
