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.

驾驶电动轮椅需要一套特定的运动、视觉和认知技能。其中一种选择是使用轮椅模拟器在受控且完全安全的环境中训练轮椅的驾驶。然而，现有的模拟器不具有多模态和具有日常生活活动训练场景的同时特征。这两个功能对于培训具有不同残疾的用户在日常生活中使用的活动非常有用，因为它可以适应大量用户，避免针对每种残疾进行特定定制。本研究提出了一种多模式电动轮椅模拟器，同时注重日常生活活动和适应性的训练。该模拟器是使用 Unity 3D 工具开发的，具有三种场景（障碍物、无障碍坡道和电梯）和三种输入控制：操纵杆、肌电图和眼动追踪。对四名具有不同残疾和驾驶电动轮椅经验的参与者进行了试点测试。参与者提高了操作轮椅的技能以及与所使用的控制相关的技能，在实验的后期阶段花费了更少的时间和精力。随着实验的进展，他们对模拟器的使用表现出了更多的信心和能力。多模式模拟器有潜力帮助个人训练和发展正确驾驶轮椅所需的运动、认知和视觉技能，同时为用户及其病理提供高度的适应性。
