We report the results of an exploratory 8-day field study of CrossTrainer: a mobile game with crossmodal audio and tactile feedback. Our research focuses on the longitudinal effects on performance with audio and tactile feedback, the impact of context such as location and situation on performance and personal modality preference. The results of this study indicate that crossmodal feedback can aid users in entering answers quickly and accurately using a variety of different widgets. Our study shows that there are times when audio is more appropriate than tactile and vice versa and for this reason devices should support both tactile and audio feedback to cover the widest range of environments, user preference, locations and tasks.

User participation has transformed the way news travel the globe. With the rise of the ‘Web 2.0 ’ phenomenon [5] users have been empowered with the means of creating and distributing informational items, which we call social feeds. Platforms like Twitter 1 and Facebook 2 provide a variety of tools to facilitate real-time communication among people. But social sites are not limited to personal chat; they also provide an effective means for organizing large groups of people in response to catastrophic disasters. Monitoring these feeds can provide time-critical information, but can easily lead to information overload due to the large amount of data being shared. In this paper we introduce a mobile auditory display application called AudioFeeds that allows users to maintain an overview of activities in different social feeds. AudioFeeds runs on a mobile device and enables users to get an overview of their social networks and spot peaks in activity by sonifying social feeds and creating a spatialised soundscape around the user’s head. We conducted a user study looking into different aspects of activity monitoring. Results show that our application provides an effective way for monitoring overall activity levels and allows users to identify activity peaks with 86.1 % accuracy even when mobile.
SmartDCap: Semi-Automatic Capture of Higher Quality Document Images from a Smartphone

People frequently capture photos with their smartphones, and some are starting to capture images of documents. How-ever, the quality of captured document images is often lower than expected, even when an application that performs post-processing to improve the image is used. To improve the qual-ity of captured images before post-processing, we developed the Smart Document Capture (SmartDCap) application that provides real-time feedback to users about the likely quality of a captured image. The quality measures capture the sharp-ness and framing of a page or regions on a page, such as a set of one or more columns, a part of a column, a figure, or a table. Using our approach, while users adjust the camera po-sition, the application automatically determines when to take a picture of a document to produce a good quality result. We performed a subjective evaluation comparing SmartDCap and the Android Ice Cream Sandwich (ICS) camera application; we also used raters to evaluate the quality of the captured im-ages. Our results indicate that users find SmartDCap to be as easy to use as the standard ICS camera application. Also, im-ages captured using SmartDCap are sharper and better framed on average than images using the ICS camera application.

This paper revisits a research methods survey from 2003 and contrasts it with a survey from 2010. The motivation is to gain insight about how mobile HCI research has evolved over the last decade in terms of approaches and focus. The paper classifies 144 publications from 2009 published in 10 prominent outlets by their research methods and purpose. Comparing this to the survey for 2000-02 show that mobile HCI research has changed methodologically. From being almost exclusively driven by engineering and applied research, current mobile HCI is primarily empirically driven, involves a high number of field studies, and focus on evaluating and understanding, as well as engineering. It has also become increasingly multi-methodological, combining and diversifying methods from different disciplines. At the same time, new opportunities and challenges have emerged.
