“…Many of them aim to provide an alternative training and rehabilitation interface for multiple tasks, as VR offers crucial advantages over real environment training. In [22], authors performed an experiment on the ViEW simulator in a rehabilitation center with 12 young patients. Their objective was to evaluate acquired skills through a custom level progression.…”

Power wheelchairs are one of the main solutions for people with reduced mobility to maintain or regain autonomy and a comfortable and fulfilling life. However, driving a power wheelchair in a safe way is a difficult task that often requires training methods based on real-life situations. Although these methods are widely used in occupational therapy, they are often too complex to implement and unsuitable for some people with major difficulties. In this context, we collaborated with clinicians to develop a Virtual Reality based power wheelchair simulator. This simulator is an innovative training tool adapted to any type of situations and impairments. In this paper, we present a clinical study in which 29 power wheelchair regular users were asked to complete a clinically validated task designed by clinicians within two conditions: driving in a virtual environment with our simulator and driving in real conditions with a real power wheelchair. The objective of this study is to compare performances between the two conditions and to evaluate the Quality of Experience provided by our simulator in terms of Sense of Presence and Cybersickness. Results show that participants complete the tasks in a similar amount of time for both real and virtual conditions, using respectively a real power wheelchair and our simulator. Results also show that our simulator provides a high level of Sense of Presence and provokes only slight to moderate Cybersickness discomforts resulting in a valuable Quality of Experience.

“…A USB voltage isolator was also used to protect the electrical circuit. The EMG signal acquisition and processing system is based on the work of [24]. According to [30,31], the most used muscles for these cases are those situated on the face (masseter, epicranial etc.).…”

“…For these people, bioelectrical signals are one of the possible resources for using a AT device. Thus, signals such as electromyography (EMG) detected from muscle EPW simulators have been under development since the 1990s in research centers in different countries [9][10][11][12][13][14][15][16][17][18][19][20][21]. The importance of these tools is perceived in clinical and rehabilitation environments that require a low-cost training tool, do not require physical space and are safe for the patient who will perform the training.…”

“…Furthermore, the simulators found in the literature have the EPW control using joystick or have only one alternative control that uses biomedical signals (EMG or oculometer). The EPW controls using the joystick, as presented in the studies of [11,17,[21][22][23][24], have as prerequisite the motor skills of the user. However, this type of control may not be possible for people with severe motor disabilities, as they may have difficulties or are unable to operate the joystick because they could not have the appropriate motor skills.…”

Driving an Electric-powered wheelchair requires a specific set of motor, visual and cognitive skills. One of the options is the use of wheelchair simulators to train the driving of the wheelchair in a controlled and completely safe environment. However, existing simulators do not have simultaneous characteristics of being multimodal and having training scenarios of activities of daily living. These two features would be very useful for training users with different disabilities in the activities they will use in daily living, as it could be adapted to a large number of users, avoiding specific customizations for each disability. This research proposes a multimodal Electric-powered wheelchair simulator with simultaneous focus in the training of activities of daily living and adaptability. The simulator was developed using the Unity 3D tool, with three scenarios (obstacles, accessibility ramp and elevators) and three input controls: joystick, electromyography and eye tracking. A pilot test was performed with four participants with different disabilities and experience in driving electric powered wheelchairs. Participants improved both their skills in operating the wheelchair and in relation to the control used, taking less time and effort at later stages of the experiment. And they demonstrated more confidence and ability in the use of the simulator as the experiment progressed. The multimodal simulator has the potential to help individuals train and develop the motor, cognitive and visual skills necessary to drive the wheelchair correctly while providing a high degree of adaptability to the user and his or her pathologies.

“…Besides its focus on manual wheelchair simulation, the purpose of the simulator is to assess spatial planning and does not match clinical assessment requirement. The other type of simulators such that miWe [15] and ViEW [16] relies on driving scenario simulation displayed on a single screen and focus on the assessment of driving simulation impact on patients through learning and training programs. Despite the lack of haptic or motion cues, they have shown benefits on training.…”

Autonomy and social inclusion can reveal themselves everyday challenges for people experiencing mobility impairments. These people can benefit from technical aids such as power wheelchairs to access mobility and overcome social exclusion. However, power wheelchair driving is a challenging task which requires good visual, cognitive and visuo-spatial abilities. Besides, a power wheelchair can cause material damage or represent a danger of injury for others or oneself if not operated safely. Therefore, training and repeated practice are mandatory to acquire safe driving skills to obtain power wheelchair prescription from therapists. However, conventional training programs may reveal themselves insufficient for some people with severe impairments. In this context, Virtual Reality offers the opportunity to design innovative learning and training programs while providing realistic wheelchair driving experience within a virtual environment. In line with this, we propose a user-centered design of a multisensory power wheelchair simulator. This simulator addresses classical virtual experience drawbacks such as cybersickness and sense of presence by combining 3D visual rendering, haptic feedback and motion cues. It relies on a modular and versatile workflow enabling not only easy interfacing with any virtual display, but also with any user interface such as wheelchair controllers or feedback devices. This paper presents the design of the first implementation as well as its first commissioning through pretests. The first setup achieves consistent and realistic behavior.
