These techniques—RNT, Storage bins, Interface Currents, Sticky Boards, and Sticky Notes—help solving the orientation problem on horizontal displays, allow to organize content on the interface in a flexible manner, and provide users with ways to annotate their objects.

These tools either fail to provide teleawareness or enable smooth transitions into and out of informal interactions. Video media spaces—always-on video links—have been proposed as a solution to this problem. However, the “always-on” nature of video media spaces results in a conflict between the desire to provide awareness and the need to preserve privacy. The present study examines distortion filtration applied to always-on video as means of resolving this tension. Our discussions include the inter-related concepts of informal interactions, awareness, and privacy; and the treatment afforded by existing distributed collaboration support tools. We then outline the present study, where our goal is to understand the effect of distortion filtration on awareness and privacy.

However, when exploring maps with different information across multiple layers and scales, users experience information discontinuity. Bancada is a multi-display system developed to investigate the exploration of geospatial information using multiple mobile devices in a multi-display environment. In Bancada, tablets are Zoomable Magic Lenses that augment, through specific geospatial layers, an overview map displayed on a tabletop or on a wall display. Users interact with lenses using touch gestures to pan and zoom; and multi-layer maps can be built by overlapping different lenses. Currently, Bancada is being used to research user interfaces separated across multiple devices and interactions with high-resolution mobile devices. Future work with Bancada includes (i) evaluating the user performance when using one tablet or multiple tablets to control all lenses; (ii) exploring what and how interactions can be performed on an overview map; and (iii) exploring how lenses can be changed.

We discuss the methodologies that we used for the evaluations, the challenges encountered and how existing HCI research methods may be used for evaluating technologies deployed in the healthcare domain.
