Placing and Recalling Virtual Items on the Skin

論文アブストラクト: The human skin provides an ample, always-on surface for input to smart watches, mobile phones, and remote displays. Using touch on bare skin to issue commands, however, requires users to recall the location of items without direct visual feedback. We present an in-depth study in which participants placed 30 items on the hand and forearm and attempted to recall their locations. We found that participants used a variety of landmarks, personal associations, and semantic groupings in placing the items on the skin. Although participants most frequently used anatomical landmarks (e.g., fingers, joints, and nails), recall rates were higher for items placed on personal landmarks, including scars and tattoos. We further found that personal associations between items improved recall, and that participants often grouped important items in similar areas, such as family members on the nails. We conclude by discussing the implications of our findings for design of skin-based interfaces.

FLIPPIN': Exploring a Paper-based Book UI Design in a Public Space

論文URL: http://dl.acm.org/citation.cfm?doid=3025453.3025981

論文アブストラクト: Digital information systems are increasingly being used in public spaces such as museums. Such systems should be easily accessible, arouse interest and offer useful information, and be easy to use. We present FLIPPIN' user interface (UI) system, which mimics the look, feel, and usability of traditional books. We explored how the paper-based book UI is designed to improve the usability problems in a public space while creating the prototypes with the aim of introducing Japanese cultural assets and conducting a field evaluation to compare the proposed system to a touch panel UI. The results of evaluation indicated the positive effects of the system, especially in terms of the usability and user's active appreciation derived from a physical book interaction. In addition, we present design guidelines derived from our findings. The suggested design guidelines are expected to facilitate the future development of effective interactive digital information systems in public spaces.

Designing Interactive Advertisements for Public Displays

論文URL: http://dl.acm.org/citation.cfm?doid=3025453.3025531

論文アブストラクト: Although public displays are increasingly being deployed in everyday situations, they are still mostly used as auto-active information sources. Adding interactivity can help to attract and engage users. We report on the design and in-the-wild evaluation of an interactive advert for a public display in a tourist information center. We evaluate and compare 3 different variants - non-interactive, interaction using body tracking, and interaction using personal mobile devices - with respect to attracting the attention and interaction from passersby. We further compare these variants with an iterated version of the body tracking system with an extended tracking area. Our findings include an unexpected reluctance of passersby to use their mobile device in public, and the increased interactive area for body interaction resulting in increased engagement and spontaneous multi-user interaction, while removing the so-called 'landing effect'. Based on our findings, we suggest guidelines for interactive adverts on public displays.
