In this paper, we introduce a novel idea of crafting a physical object in tandem with the physical exercise using the heart rate patterns. Our aim is provide a new way of visualizing the exercise intensity. We present Sweat-Atoms, a 3D modeling and printing system, which generates abstract 3D designs using the heart rate patterns of individuals engaged in a physical activity. The crafted physical objects can act as souvenirs and be testimony to the human efforts invested in performing the physical activity. We believe the creative experience of crafting will help to change the monotonous nature of physical exercise.

This video demonstrates Flexpad, a highly flexible display interface. Flexpad introduces a novel way of interacting with flexible displays by using detailed deformations. Using a Kinect camera and a projector, Flexpad transforms virtually any sheet of paper or foam into a flexible, highly deformable and spatially aware handheld display. It uses a novel approach for tracking deformed surfaces from depth images very robustly, in high detail and in real time. As a result, the display is considerably more deformable than previous work on flexible handheld displays, enabling novel applications that leverage the high expressiveness of detailed deformation. We illustrate these unique capabilities through three application examples: curved cross-cuts in volumetric images, deforming virtual paper characters, and slicing through time in videos.

A user working with his/her desktop computer would benefit from notifications (e.g., the arrival of e-mail, micro-blogs, and application updates) being given at adequate times when he/she is interruptible. To do so, a notification system needs to determine the user's state of activity. In this paper, we propose a novel method for estimating user states with a pressure sensor on a desk. We use a lattice-like pressure sensor sheet and distinguish between two simple user states: interruptible or not. The pressure can be measured without the user being aware of it, and changes in the pressure reflect useful information such as typing, an arm resting on the desk, mouse operation, and so on. We carefully developed features that can be extracted from the sensed raw data, and we used a machine learning technique to identify the user's interruptibility. We conducted experiments for two different tasks to evaluate the accuracy of our proposed method and obtained promising results.

In this paper we describe t-words (tangible words) an interface that consists of rectangular blocks in which children can record and then playback audio. The blocks can then be snapped together playing the recorded audio in a sequence, by reordering the blocks in different ways the audio sequence changes according to the order of the blocks. t-words does not need a computer, which makes it flexible for various contexts. The interface was presented during two workshops that took place in Kathmandu - Nepal with two schools. During the workshops children used the interface playfully exploring sounds, words and sentences while engaging in collaborative work.

This paper describes the macro-ergonomics approach currently being delivered in collaboration with a West Australian school community to ensure healthy computing for students in middle school (ages 11- 17 Years). Background: Introduction of notebook computers in many schools has become integral to learning. While this is rewarding from an educational perspective, increased screen-based exposure has been associated with potential risks to physical and visual health. Unhealthy computing behaviours include frequent and long durations of exposure; awkward postures due to inappropriate furniture and workstation layout, and ignoring computer-related discomfort. Methods: This research uses a community-based participatory research approach. Students in Year 7 in 2011 at a co-educational middle school, their parents, and teachers have been recruited. Baseline data was collected on students' knowledge of computer ergonomics, current notebook exposure, and attitudes towards healthy computing behaviours; and teachers' and self-perceived competence to promote healthy notebook use among students, and what education they wanted. The intervention phase is a health promotion program that is being developed by an inter-professional team in collaboration with students, teachers and parents to embed concepts of ergonomics education in relevant school activities and school culture. End of year changes in reported and observed student computing behaviours will be used to determine the effectiveness of the program. Significance: Building a body of evidence regarding physical health benefits to students from this school-based ergonomics program can guide policy development on the healthy use of computers within children's educational environments. Additionally, an approach that attends to epidemiological risk factors, whole community attitudes, environmental factors and the organizational environment and culture of the community is essential.

This paper reports on experience design work currently in progress. "Wet Pixels" is intended to stimulate discussion around the notion of reproducing original digital images in a physical medium. The prototype's design is informed by mechanical reproduction devices (e.g. relief press, large format camera) and retrospective print processes (halftone, dot matrix). The original conceptual design (Figure 1) constitutes a miniature camera encased in a wooden viewing frame that would enable viewers to select and capture photographs. This image could subsequently be printed onto Japanese paper using an Arduino-controlled matrix of stepper motors topped with paint-tipped sponges. When presented in a gallery, Wet Pixels provides users with greater sensory feedback (physical, visual, auditory) than entirely digital processes through tangible creative mark-making on to paper.

Mobile interaction presents challenges that go beyond the traditional desktop contexts. These difficulties become even greater when considering people with disabilities or people without disabilities that experience situational impairments. Further, mobile devices and interfaces have been evolving at an astonishing rate which leads to increasing difficulties in maturing the field and consequently to ensure accessibility by different people and under different circumstances. This workshop aims to bring together researchers from the Mobile HCI, Mobile Accessibility, and Mobile Web areas, towards identifying the most prominent challenges for mobile accessibility and guidelines for a more structured and faster development of accessible solutions.

The operational challenges faced by law enforcement and public safety personnel are constantly evolving, while the training and certification process has stayed the same. New technologies such as virtual reality, mixed reality, or game-based simulators are being researched as promising enhancements to traditional training methods. However, their widespread adoption, particularly by smaller units, faces barriers such as cost - due in no small part to the difficulties of developing and especially evaluating such large-scale interactive systems. In this case study, we present MINT - a low-cost mixed-reality Multimodal INteractive Training system, aimed at supporting the training of small- and medium-sized law enforcement and infantry units. We discuss the challenges and approaches taken in the participatory design of the training system, its agile-based development and implementation, and its qualitative evaluation with users and subject-matter experts.

Research on personalization has mostly focused on improving low-level aspect of user's performance (e.g. time to access a command) or automating tasks for accommodating the different needs of individuals. Thus, the results of that research has often led to the design of personalization facilities that allow users to accomplish their goals faster. While this is a valuable outcome, personalization research has given little attention to supporting individual differences beyond those related to user's performance. For my PhD research, I explore 1) behavioral differences in the context of personal task management, and 2) the design of personalization facilities that can accommodate such differences.
