“…This low cost technology is designed to track the hand of a user, within the field of view (FOV) of the camera. However as noted by [48], the limited FOV, dependency on environmental conditions, and performance with objects in FOV, are limitations with using this technology for home-based rehabilitative applications. Motion capture systems that make use of an electromagnetic field and attachable sensors (that act as markers) have been labeled as an electromagnetic tracker in this manuscript, as shown in [49] and [50] to monitor reaching movements, such systems are able to monitor the position and orientation of each sensor.…”

Movement sonification is emerging as a useful tool for rehabilitation, with increasing evidence in support of its use. To create such a system requires component considerations outside of typical sonification design choices, such as the dimension of movement to sonify, section of anatomy to track, and methodology of motion capture. This review takes this emerging and highly diverse area of literature and keyword-code existing real-time movement sonification systems, to analyze and highlight current trends in these design choices, as such providing an overview of existing systems. A combination of snowballing through relevant existing reviews and a systematic search of multiple databases were utilized to obtain a list of projects for data extraction. The review categorizes systems into three sections: identifying the link between physical dimension to auditory dimension used in sonification, identifying the target anatomy tracked, identifying the movement tracking system used to monitor the target anatomy. The review proceeds to analyze the systematic mapping of the literature and provide results of the data analysis highlighting common and innovative design choices used, irrespective of application, before discussing the findings in the context of movement rehabilitation. A database containing the mapped keywords assigned to each project are submitted with this review.

“…Tracking outside the camera field of view is not included. Additionally, precision, tolerance (e.g., towards light inference), limited data capture, and operating system compatibility are issues with optical hand-tracking devices that impede the technology (Gamboa et al, 2019). These limitations make the devices problematic in fast changing environments, as, for instance, when needed for the replication of manufacturing tasks (see implications for practice).…”

Introduction: Using our own hands allows humans to interact with the real world, as we learn from an early age. Virtual reality (VR) gloves allow a similar interaction in VR by transferring hand movements through natural mapping. Research outside the VR domain has already shown that this process creates a high level of presence and perceived naturalness. Research in the VR context, on the other hand, is still in an early stage and lacks explorative qualitative research following a human-centered approach and including the direct perceptions of users on mapped controls in system design. Against that background, this research investigates natural mapping in the VR context qualitatively. The study examines how participants experience VR input devices with different degrees of natural mapping (VR gloves, a Valve index controller, and an HTC Vive controller) on perceived naturalness, spatial presence, embodiment, and cognitive absorption.Methods: A focus group (N = 20 aged 22–36) did the VR experience with the devices and was asked about their experience in semi-structured interviews. Questions focused on perceived naturalness, spatial presence, cognitive absorption, and embodiment with the three devices. Data were analyzed using qualitative content analysis.Results: Feedback on spatial presence was widely positive for the VR glove due to the highly natural perceived movement capabilities. Mapping with the partly mapped index controller was also seen as natural and immersing if the movement matched the operated actions in the system. Participants mainly perceived the highest degree of cognitive absorption and embodiment while doing the task with the VR glove.Discussion: The findings indicate that the natural mapping capabilities of VR input devices strongly influence spatial presence. The VR glove stands out while being able to induce a feeling of embodiment in most cases. Furthermore, participants reported a connection between natural mapping and perceived cognitive absorption in the task.

“…Popovic et al [29] reported that feedback-mediated exercise for poststroke rehabilitation of a hemiplegic arm increased patient motivation (such as interest, enjoyment, and perceived competence) and promoted greater improvement of motor function including speed and smoothness compared to no-feedback exercise. Furthermore, physical therapy containing gami cation elements helped patients remain engaged in rehabilitation [30]. It is especially important to be able to continue without getting bored in equipment-mediated rehabilitation.…”

Fine motor dysfunction and cognitive impairments commonly develop after stroke, which greatly impact the daily lives of patients. In current occupational therapy, hand dexterity and cognitive functions are evaluated individually (e.g., by manipulation of small objects with ngers, or a paper-and-pencil test), which is insuf cient for therapists to grasp the total ability of combined dexterity and cognition in everyday situations. Additionally, the traditional methods require a tester to measure the completion time manually and tend to be monotonous for patients. These problems would be solved using technology. This study aimed to develop a new electric pegboard (e-Peg) prototype and to investigate preliminary utility in healthy adults. The system judges the peg insertion accuracy based on magnetism and records the time course and scores, which are linked to human object manipulation ability. The e-Peg executes three types of tasks: a basic color matching task (BT), a color comparison task using a pattern sheet (CT), and a visual memory task (MT), with one/two-color sample patterns. Six older and nine younger healthy adults performed the e-Peg tasks, functional tests, and responded to questionnaires. As a result, the number of correct answers in a bicolor symmetrical MT were signi cantly greater in the younger group than in the older group. The older group required a signi cantly longer completion time for BT and CT than the younger group. Signi cant correlations were found between one-color BT/ CT and dexterity tests, between bicolor BT/CT and dexterity/cognitive tests, and between a bicolor MT and a cognitive test. Questionnaire results revealed that participants regarded BT/CT as easy/interesting tasks, whereas MT was considered a dif cult/challenging task. In conclusion, our e-Peg is potentially a useful rehabilitation device that facilitates many tasks related to hand manipulation and attention/executive functions, and a valuable tool for personalized therapy.
