Conventional center-based cardiac rehabilitation adherence is poor, adversely affecting long-term efficacy. Innovative strategies such as telerehabilitation are perceived as promising alternatives to improve care delivery. This paper presents the results of prior and ongoing work on the design and development of MobileHeart, a telemedical smartphone-based application to be used in secondary prevention...
Gravity compensation (GC) of the arm is used to facilitate arm movements in conventional therapy as well as in robot-assisted rehabilitation of neurologically impaired persons. Positive effects of GC on Range of Motion (ROM) have been demonstrated in stroke. In Multiple Sclerosis (MS), research regarding this topic is lacking. Since an active participation of the patient is required for effective...
Complex 3D interaction in virtual environments may inhibit user interaction and cause frustration. Supporting adaptivity based on the detected user frustration can be considered as one promising solution to enhance user interaction. Our work proposes to provide adaptive assistance to users who are frustrated during their interaction with 3D user interfaces in virtual environments. The obtrusiveness...
Users often become frustrated when they are unable to understand and control a pervasive computing environment. Previous studies have shown that allowing users to pose why and why not questions about context-aware applications resulted in better understanding and stronger feelings of trust. Although why and why not questions have been used before to aid in debugging and to clarify graphical user interfaces,...
Pervasive applications are typically realized through ad-hoc service and user interface compositions. While many tools focus on the development of pervasive services by masking the complex technical side of a pervasive computing environment, the deployment of an application as a whole -- i.e. a set of services and user interfaces -- is often forgotten. We present an alternative design strategy and...
Human activity is highly influenced by the context and environment of the user. Presence of other users in the vicinity can also influence the context of use and thus activity. In ubiquitous computing environments, people are surrounded by numerous computing devices helping them to carry out various tasks. However, users seek precise and fine-grained information that is not provided by the computing...
Force feedback in the context of a rehabilitation program may have its benefits. The generated forces can be used to assist, support or oppose the patients according to their personal needs and abilities. Using the Phantom haptic device, we conducted a pilot study focussing on the rehabilitation of the upper limbs in MS patients. Apart from the promising clinical results, we found that only a few...
The work addresses the problem of coping with a diversity of location tracking techniques available in ubiquitous computing environments. We investigate how this diversity can be embedded in the environment in a way that typical difficulties coming from using location-awareness are hidden. We present an approach to improve location-awareness of these environments by means of integrating the knowledge...
In current mobile user interface design tools, it is time consuming to export a design to the target device. This makes it hard for designers to iterate over the user interfaces they are creating. We propose Gummy-live, a GUI builder for mobile devices allowing designers to test and observe immediately on the target device each step they take in the GUI builder. This way, designers are stimulated...
When interacting in a virtual environment, users are confronted with a number of interaction techniques. These interaction techniques may complement each other, but in some circumstances can be used interchangeably. Because of this, it is difficult for the user to determine which interaction technique to use. Furthermore, the use of multimodal feedback, such as haptics and sound, has proven beneficial...
Upper limb weakness due to Multiple Sclerosis has a major negative effect on the functional activities of the patient. Promising developments in the field of rehabilitation robotics may enable additional exercise. This study aims to investigate which types of robotic outcome measures are clinically relevant, in preparation of the evaluation for intervention studies.Within this context, appropriate...
Interactive software applications are increasingly finding their way to cultural and tourist sites. During the development of a coal mine museum on the former mine site of Beringen (Province of Limburg, Belgium), we explored the possibilities of such interactive systems, suitable for the specific site and the intended target group. In particular, we concentrated on a mobile location-based educational...
Multi-touch large display interfaces are becoming increasingly popular in public spaces. These spaces impose specific requirements on the accessibility of the user interfaces: most users are not familiar with the interface and expectations with regard to user experience are very high. Multi-touch interaction beyond the traditional move-rotate-scale interactions is often unknown to the public and can...
Pervasive computing environments are complex to interact with due to the dynamic assembly of interaction resources and the need to adapt to sudden changes in the environment configuration. When the complexity of such an environment is masked by the underlying computing system, end-users are often left with limited or no control over their interactive space. This brings up the need to make users aware...
The increasing complexity of pervasive computing environments puts the current software development methods to the test. There is a large variation in different types of hardware that need to be addressed. Besides, there is no guarantee the environment does not evolve, making the software developed for the initial environment deprecated and in need for updates or reconfiguration. Software deployed...
The diversity of end-user devices in combination with a growing user base poses important challenges for providing easy access to the huge amount of content and services currently available. Each device has its typical set of capabilities and characteristics that must be taken into account to create an appropriate user interface that provides interactive access to multimedia data and services. Furthermore,...
During the past few years, personal portable computer systems such as PDAs or laptops are being used in different contexts such as in meetings, at the office, or at home. In the current era of multimodal interaction, each context may require other interaction strategies or system settings to allow the end-users to reach their envisioned goals. For instance, in a meeting room a user may want to use...
We present a multilayer architecture for pervasive computing in heterogeneous environments: the general adaptable services manager (GASM). This architecture allows a developer to build context-aware multi-platform applications by means of a set of core services such as device discovery and integration, flexible software component deployment, heterogeneous network communication broker and adaptable...
Web services are todays preferred vehicle for creating service-oriented architectures (SOA). Due to the boom of personal networked devices, the Web also found its way to the mobile space. This gives rise to device hosted mobile services that deliver functionality over a wireless network. There is potential to unite these services in a collaborative service space and exploit them as building blocks...
Object selection is a primary interaction technique which must be supported by any interactive three-dimensional virtual reality application. Although numerous techniques exist, few have been designed to support the selection of objects in dense target environments, or the selection of objects which are occluded from the user's viewpoint. There is, thus, a limited understanding on how these important...
