Schraefel, MC, André, Paul, White, Ryen, Tan, Desney, Berners-Lee, Tim, Consolvo, Sunny, Jacobs, Robert, Kohane, Issac, Dantec, Christopher A. La, Mamykina, Lena, Marsden, Gary and Shneiderman, Ben (2009): Interacting with eHealth: towards grand challenges for HCI. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 3309-3312. Available online

“While health records are increasingly stored electronically, we have little access to this data about ourselves. We're not used to thinking of these official records either as ours or as something we'd understand if we had access to them in any case. We increasingly turn to the Web, however, to query any ache, pain or health goal we may have before consulting with health care professionals. Likewise, for proactive health care, such as nutrition or fitness, or post diagnosis support, to find fellow-sufferers, we turn to online resources. There is, it seems, a potential disconnect between points at which professional and proactive health care intersect. Such gaps in information sharing may have direct impact on practices we decide to take up, the care we seek, and the support professionals offer. In this panel, we consider several places within proactive, preventative health care in particular HCI has a role towards enhancing health knowledge discovery and health support interaction. Our goal is to demonstrate how now is the time for eHealth to come to the forefront of the HCI research agenda.”

Maunder, Andrew J., Marsden, Gary and Harper, Richard (2008): SnapAndGrab: accessing and sharing contextual multi-media content using bluetooth enabled camera phones and large situated displays. In: Proceedings of ACM CHI 2008 Conference on Human Factors in Computing Systems April 5-10, 2008. pp. 2319-2324. Available online

“In this paper we describe a novel interaction technique that allows users to access and share rich multi-media content via a large, situated public display and their own Bluetooth enabled camera phone. The proposed system differs from other solutions in that it does not require any client software to be installed on the user's device. We believe that our solution provides a practical and holistic approach for device-based interactions with a public multi-media information system.”

“This paper explores novel interfaces for First Person Shooting (FPS) games on Personal Digital Assistant (PDA) devices. We describe a new approach inspired by a study of the interaction patterns used in desktop FPS games. Intelligent gesture recognition, based on these patterns, is used to create an optimal implementation of basic game functions (i.e., jump, shoot, walk forward). This new interaction system is evaluated through a prototype 3D FPS game. We believe the newly designed interface more adequately leverages the interaction capabilities of current PDAs, to better solve the problem of rapidly and accurately executing a large number of gaming commands.”

“In this paper, we conduct a thorough investigation of how people search their photo collections for events (a set of photographs relating to a particular well defined event), singles (individual photographs) and properties (a set of photographs with a common theme) on PDAs. We describe a prototype system that allows us to expose many issues that must be considered when designing photo searching interfaces. We discuss each of these issues and make recommendations where applicable. Our major observation is that several different methods are used to locate photographs. In light of this, we conclude by discussing how photo searching interfaces might embody or support such an approach.”

Jones, Steve, Jones, Matt, Marsden, Gary, Patel, Dynal and Cockburn, Andy (2005): An evaluation of integrated zooming and scrolling on small screens. In International Journal of Human-Computer Studies, 63 (3) pp. 271-303

“Speed-dependent automatic zooming (SDAZ) has been proposed for standard desktop displays as a means of overcoming problems associated with the navigation of large information spaces. SDAZ combines zooming and panning facilities into a single operation, with the magnitude of both factors dependent on simple user interaction. Previous research indicated dramatic user performance improvements when using the technique for document and map navigation tasks. In this paper, we propose algorithmic extensions to the technique for application on small-screen devices and present a comparative experimental evaluation of user performance with the system and a normative scroll-zoom-pan interface. Users responded positively to the system, particularly in relation to reduced physical navigational workload. However, the reduced screen space reduced the impact of SDAZ in comparison to that reported in previous studies. In fact, for one-dimensional navigation (vertical document navigation) the normative interface out-performed SDAZ. For navigation in two dimensions (map browsing) SDAZ supports more accurate target location, and also produces longer task completion times. Some SDAZ users became lost within the information space and were unable to recover navigational context. We discuss the reasons for these observations and suggest ways in which limitations of SDAZ in the small-screen context may be overcome.”

“This paper describes a new way of visualizing threaded discussion forums on compact displays. The technique uses squarified treemaps to render the threads in discussion forums as colored rectangles, thereby using 100% of the limited screen space. We conducted a preliminary user study, which compared the treemap version and a traditional text based tree interface. This showed that the contents of the discussion forum were easily grasped when using a treemap, even though there were in excess of one hundred threads. In particular our technique showed a significant improvement in time for finding the largest and most active threads. Overall, it was shown that the benefits derived from using treemaps on desktop computers are still valid for small screens.”

Marsden, Gary and Tip, Nicholas (2005): Navigation control for mobile virtual environments. In: Proceedings of 7th conference on Human-computer interaction with mobile devices and services 2005. pp. 279-282. Available online

“In this paper, we describe a project which uses PDAs to provide an interactive experience with a virtual environment. In particular, we focus on the navigational aspects of allowing the users to move through, and view, the environment. As this system will be deployed in a museum, it was crucial that the navigation be as intuitive as possible. To that end, we developed and evaluated two prototypes: one was based purely on gesture, whilst the other used a combination of gesture and keypad. For the purposes of our application, the combination of keypad and gesture provided the most effective.”
