“…Similarly, Taske et al [30] present the design of motor rehabilitation program for stroke patients that uses mini-games in VR to motivate patients. Barros et al [4] provide a survey on recent research with regard to the use of VR for different medical purposes: training aimed at improving the gait pattern in patients with Parkinson's disease; helping to improve spatial perception in children with cerebral palsy; post-operative treatment of patients who suffered surgeries of the hand and rehabilitation of stroke patients. Barros et al [4] conclude that VR enables real-world situations to be simulated, thereby giving the therapist full control over the variables related to the health aspects of interest.…”

For a better understanding of how different disorders affect motor function, a uniform, standardized and objective evaluation is a desirable goal for the clinical community. We explore the potential of Augmented Reality (AR) combined with serious gaming and free hand tracking to facilitate objective, cost-effective and patient-friendly methods for evaluation of upper extremity motor dysfunction in different patient groups. In this paper, we describe the design process of the game and the system architecture of the AR framework to meet these requirements. Furthermore, we report our findings from two pilot studies we conducted with healthy people aged over 50. First, we present a usability study (n = 5) on three different modalities of visual feedback for natural hand interaction with AR objects (i. e., no augmented hand, partial augmented hand and a full augmented hand model). The results show that a virtual representation of the fingertips or hand improves the usability of natural hand interaction. Secondly, a study about game engagement is presented. The results of this experiment (n = 8) show that there might be potential for engagement, but usability needs to be improved before it can emerge.

“…Analyzing the GEQ questions led to the following results for the 7 dimensions defined in [11]: the game scored high on 'sensory and imaginative immersion', 'competence', and 'positive affect', all with median [interquartile range] values 4 [3,4]. Low scores were obtained on 'negative affect' and 'tension and annoyance', with 2 [1,3].…”

For a better understanding of how different diseases (e.g. neurovascular diseases, neurodegenerative diseases, and musculoskeletal pain conditions) affect human motor function, a uniform, standardized and objective evaluation is a desirable goal expressed within the clinical community. We explore the capabilities of an augmented reality (AR) game that uses free hand interaction to facilitate an objective assessment of the upper extremity motor dysfunction. First, the design process of the game and the system architecture are described. Second, a study about usability of the AR framework and game engagement is presented based on an experiment we conducted with five patients and ten healthy people. Lastly, a short analysis of the accuracy of the hand data when participants performed "fingers tapping" gesture is done. The results of the study show that even though users experienced the system as physically and mentally demanding, it was engaging enough to make them complete the game. The study also shows that hand data captured is accurate enough to allow a high degree (95%) of pinching gesture recognition.

“…Virtual reality (VR) totally immerses a user in a completely synthetic world [30]. VR has already proven to offer great opportunities for rehabilitation of several patient groups [3], as it enables real-world situations to be simulated, thereby giving the therapist full control over parameters (e.g. sizes, distances, velocities, trajectories etc.)…”

Advances in technology offer new opportunities for a better understanding of how different disorders affect motor function. In this paper, we explore the potential of an augmented reality (AR) game implemented using free hand and body tracking to develop a uniform, cost-effective and objective methods for evaluation of upper extremity motor dysfunction in different patient groups. We conducted a study with 20 patients (10 Parkinson's Disease patients and 10 stroke patients) who performed hand/arm movement tasks in four different conditions in AR and one condition in real world. Despite usability issues mainly due to non-robust hand tracking, the patients were moderately engaged while playing the AR game. Our findings show that moving virtual objects was less targeted, took more time and was associated with larger trunk displacement and a lower variability of elbow angle and upper arm angle than moving real objects. No significant correlations were observed between characteristics of movements in AR and movements in the real world. Still, our findings suggest that the AR game may be suitable for assessing the hand and arm function of mildly affected patients if usability can be further improved.
