Abstract

BACKGROUND

Children with severe disabilities are sometimes unable to access powered mobility training. Thus, we developed the Kinect-Wheelchair Interface Controlled (KWIC) smart wheelchair trainer that converts a manual wheelchair into a powered wheelchair. The KWIC Trainer uses computer vision to create a virtual tether with adaptive shared-control between the wheelchair and a therapist during training. It also includes a mixed-reality video game system.

METHODS

We performed a year-long usability study of the KWIC Trainer at a local clinic, soliciting qualitative and quantitative feedback on the device after extended use.

RESULTS

Eight therapists used the KWIC Trainer for over 50 hours with 8 different children. Two of the children obtained their own powered wheelchair as a result of the training. The therapists indicated the device allowed them to provide mobility training for more children than would have been possible with a demo wheelchair, and they found use of the device to be as safe as or safer than conventional training. They viewed the shared control algorithm as counter-productive because it made it difficult for the child to discern when he or she was controlling the chair. They were enthusiastic about the video game integration for increasing motivation and engagement during training. They emphasized the need for additional access methods for controlling the device.

CONCLUSION

The therapists confirmed that the KWIC Trainer is a useful tool for increasing access to powered mobility training and for engaging children during training sessions. However, some improvements would enhance its applicability for routine clinical use.

摘要

背景

重度残疾儿童有时无法接受电动移动训练。因此，我们开发了由Kinect轮椅接口控制（KWIC）的智能轮椅训练器，它能将手动轮椅转变为电动轮椅。KWIC训练器利用计算机视觉在训练过程中创建一个虚拟系绳，实现轮椅与治疗师之间的自适应共享控制。它还包括一个混合现实视频游戏系统。

方法

我们在当地一家诊所对KWIC训练器进行了为期一年的可用性研究，在长期使用后收集有关该设备的定性和定量反馈。

结果

八位治疗师使用KWIC训练器与八名不同的儿童进行了超过50小时的训练。其中两名儿童通过训练获得了自己的电动轮椅。治疗师表示，该设备使他们能够为比使用演示轮椅时更多的儿童提供移动训练，并且他们发现使用该设备与传统训练一样安全或更安全。他们认为共享控制算法适得其反，因为这使得儿童难以辨别自己何时在控制轮椅。他们对视频游戏集成在训练期间增加动力和参与度方面充满热情。他们强调需要增加控制该设备的其他接入方法。
