Computer‐based systems for motor function rehabilitation have been around for more than a decade, with work done to help recovery of function in the lower limb (ankle, leg) as well as upper limb (hand and arm).

More recently there has been a trend towards the use of game‐based systems to deliver rehabilitation goals. The authors' interdisciplinary group has been working in the area of motor function recovery of the hand and arm (following stroke) for a number of years, using both high‐end virtual reality (VR) technology as well as low‐cost video capture technology.

Over this time it has become clear that there are many challenges in designing usable, effective game‐based systems for motor function rehabilitation.

This paper reflects on user experiences across the range of technologies developed by the group. It presents a summary review of the authors' systems and details the protocols and user evaluation instruments used. It then critically reflects on this work and reviews other recent advances in game usability and playability, leading to suggestions for how the user experience of games for rehabilitation may be improved in future work.

The Leap Motion represents a new generation of depth sensing cameras designed for close range tracking of hands and fingers, operating with minimal latency and high spatial precision (0.01 mm). The purpose of this paper is to develop virtual reality (VR) simulations of three well-known hand-based rehabilitation tasks using a commercial game engine and utilising a Leap camera as the primary mode of interaction. The authors present results from an initial evaluation by professional clinicians of these VR simulations for use in their hand and finger physical therapy practice.

A cross-disciplinary team of researchers collaborated with a local software company to create three dimension interactive simulations of three hand focused rehabilitation tasks: Cotton Balls, Stacking Blocks, and the Nine Hole Peg Test. These simulations were presented to a group of eight physiotherapists and occupational therapists (n=8) based in the Regional Acquired Brain Injury Unit, Belfast Health, and Social Care Trust for evaluation. After induction, the clinicians attempted the tasks presented and provided feedback by filling out a questionnaire.

Results from questionnaires (using a Likert scale 1-7, where 1 was the most favourable response) revealed a positive response to the simulations with an overall mean score across all questions equal to 2.59. Clinicians indicated that the system contained tasks that were easy to understand (mean score 1.88), and though it took several attempts to become competent, they predicted that they would improve with practice (mean score 2.25). In general, clinicians thought the prototypes provided a good illustration of the tasks required in their practice (mean score 2.38) and that patients would likely be motivated to use the system (mean score 2.38), especially young patients (mean score 1.63), and in the home environment (mean score 2.5).

Cameras offer an unobtrusive and low maintenance approach to tracking user motion in VR therapy in comparison to methods based on wearable technologies. This paper presents positive results from an evaluation of the new Leap Motion camera for input control of VR simulations or games. This mode of interaction provides a low cost, easy to use, high-resolution system for tracking fingers and hands, and has great potential for home-based physical therapies, particularly for young people.

Motion capture system (MoCap) has been used in measuring the human body segments in several applications including film special effects, health care, outer-space and under-water navigation systems, sea-water exploration pursuits, human machine interaction and learning software to help teachers of sign language. The purpose of this paper is to help the researchers to select specific MoCap system for various applications and the development of new algorithms related to upper limb motion.

This paper provides an overview of different sensors used in MoCap and techniques used for estimating human upper limb motion.

The existing MoCaps suffer from several issues depending on the type of MoCap used. These issues include drifting and placement of Inertial sensors, occlusion and jitters in Kinect, noise in electromyography signals and the requirement of a well-structured, calibrated environment and time-consuming task of placing markers in multiple camera systems.

This paper outlines the issues and challenges in MoCaps for measuring human upper limb motion and provides an overview on the techniques to overcome these issues and challenges.

The emergence of mobile health (mHealth) products has created a capability of monitoring and managing the health of patients with chronic diseases. These mHealth technologies would not be beneficial unless they are adopted and used by their target users. This study identifies key factors affecting the usage of mHealth apps based on user usage data collected from an mHealth app.

Using a dataset collected from an mHealth app named mPower, developed for patients with Parkinson's disease (PD), this paper investigated the effects of disease diagnosis, disease progression and mHealth app difficulty level on app usage, while controlling for user information. App usage is measured by five different activity counts of the app.

The results across five measures of mHealth app usage vary slightly. On average, previous professional diagnosis and high user performance scores encourage user participation and engagement, while disease progression hinders app usage.

The findings potentially provide insights into better design and promotion of mHealth products and improve the capability of health management of patients with chronic diseases.

Studies on the mHealth app usage are critical but sparse because large-scale and reliable mHealth app usage data are limited. Unlike earlier works based solely on survey data, this research used a large user usage data collected from an mHealth app to study key factors affecting app usage. The methods presented in this study can serve as a pioneering work for the design and promotion of mHealth technologies.

This chapter argues that the concept of ‘mass supervision’, and indeed the concept of ‘mass incarceration’ from which it derives, is both quantitatively and qualitatively indeterminate when applied outside of the context of the US. However, the qualitative indeterminacy of mass supervision only holds so long as one treats the word ‘mass’ as being an analogy to mass consumption. This chapter therefore considers an alternative construction of ‘mass’ punishment in terms of mass production. Comparing the philosophies of production associated with Henry Ford and William Morris with the scholarship of Michel Foucault and Fergus McNeill reveals that mass supervision can authentically claim to be qualitatively ‘massive’, given the bespoke and one-on-one nature of traditional supervision. It is thus possible to speak coherently of ‘mass supervision’ in an international context, although this negative conception of a problem invites questions about the best solution that it generally leaves open.

This chapter provides a brief overview of community sanctions in Australia and examines the extent to which McNeill’s analysis in Pervasive Punishment (2019) is applicable in the Australian context. Two key issues in the Australian context are, firstly, state and territory-level variations within a federal political structure, and secondly, disproportionate Indigenous imprisonment and community sanction rates and the generally destructive impact of the criminal legal system on Indigenous communities and peoples. The chapter argues that developing a better agonistic politics around community sanctions requires descending from the broad level of historical and sociological analysis to examine state and territory-level variations in judicial and correctional structures, histories and cultures. Further, that Australian community sanctions cannot be understood without a primary focus on the differences between Indigenous and non-Indigenous rates, experiences and meaning. The key to addressing the destructive impact of criminal legal processes and practices on Indigenous peoples lies in developing Indigenous governance, empowerment, self-determination, sovereignty and nation-building. Two recent developments promoting Indigenous governance are examined: the Uluru Statement from the Heart and Justice Reinvestment projects initiated by First Nations communities, highlighting the importance of activism, contest and struggle by community organisations.
