The objective of the study was to develop and implement an architecture for remote training that can be used in the narrowband home telemedicine environment. A remote training architecture, the REmote Patient Education in a Telemedicine Environment (REPETE) architecture, using a remote control protocol (RCP) was developed. A set of design criteria was specified. The developed architecture was integrated into the IDEATel home telemedicine unit (HTU) and evaluated against these design criteria using a combination of technical and expert evaluations. Technical evaluation of the architecture demonstrated that remote cursor movements and positioning displayed on the HTU were smooth and effectively real-time. The trainers were able to observe within approximately 2 seconds lag what the patient sees on their HTU screen. Evaluation of the architecture by experts was favorable. Responses to a Likert scale questionnaire regarding audio quality and remote control performance indicated that the expert evaluators thought that the audio quality and remote control performance were adequate for remote training. All evaluators strongly agreed that the system would be useful for training patients. The REPETE architecture supports basic training needs over a narrowband dial-up connection. We were able to maintain an audio chat simultaneously with performing a remote training session, while maintaining both acceptable audio quality and remote control performance. The RCP provides a mechanism to provide training without requiring a trainer to go to the patient's home and effectively supports deictic referencing to on screen objects.
本研究的目的是开发并实施一种可用于窄带家庭远程医疗环境的远程培训架构。利用远程控制协议（RCP）开发了一种远程培训架构，即远程医疗环境中的远程患者教育（REPETE）架构。制定了一套设计标准。将开发的架构集成到IDEATel家庭远程医疗单元（HTU）中，并结合技术评估和专家评估，对照这些设计标准进行评估。对该架构的技术评估表明，在HTU上显示的远程光标移动和定位流畅且基本实时。培训人员能够在大约2秒的延迟内观察到患者在其HTU屏幕上看到的内容。专家对该架构的评估结果良好。针对音频质量和远程控制性能的李克特量表问卷的回复表明，专家评估人员认为音频质量和远程控制性能足以满足远程培训的需求。所有评估人员都强烈认为该系统对培训患者有用。REPETE架构通过窄带拨号连接支持基本培训需求。我们能够在进行远程培训课程的同时保持音频聊天，同时保持可接受的音频质量和远程控制性能。RCP提供了一种无需培训人员前往患者家中即可进行培训的机制，并有效地支持对屏幕上对象的指示性引用。
