摘要

智能步行者和虚拟现实（VR）已经被提出用于帮助残疾老年人进行身体康复。然而，新技术可能会影响康复期间的情感反应（ARs），进而影响参与者的依从性。目的本研究旨在评估老年人在沉浸式VR场景下智能助行器辅助步态的ar。方法老年患者14例(年龄66.29±3.81岁；高度= 1.63±0.09 m；体重= 71.26±10.19 kg)在沉浸式VR场景（VRS）中进行智能助行器辅助步态（SWS）和智能助行器辅助步态（SWS）。每组持续10.5分钟（工作与休息比为90:90秒）。对感觉量表（FS）进行基线、刺激间和运动后测量。刺激间和运动后测量认知负荷（CL）和感知运动等级（RPE）。运动后测量自我效能（SE）、未来意向（FI）和系统可用性量表（SUS）。在休息和运动期间达到的最大心率百分比（%HRmax）。结果显示FS、CL或RPE在组内或组间无显著差异，SE、FI或SUS在组间无显著差异(p >；0.05)。参与者经历低CL和高FS、SE、FI和SUS水平。此外，会话强度被分类为“非常、非常容易”到“容易”（RPE）和“非常轻”到“轻”（%HRmax）。在沉浸式VR场景中，智能助行器辅助的步态会话有利于参与者的ar，显示出提高老年人参与度的希望。

Evaluation of human-machine interaction based on affective responses of elderly people during smart walker-assisted gait in an immersive virtual reality scenario

Background

Smart walkers and virtual reality (VR) have been proposed to assist elderly people with disabilities during physical rehabilitation. However, new technologies may impact affective responses (ARs) during rehabilitation sessions and, in turn, the participants' adherence.

Purpose

This study aimed to evaluate the ARs of elderly people during smart walker-assisted gait in an immersive VR scenario.

Methods

Fourteen elderly (age = 66.29 ± 3.81 years; height = 1.63 ± 0.09 m; body mass = 71.26 ± 10.19 kg) performed a smart walker-assisted gait session (SWS) and smart walker-assisted gait session in an immersive VR scenario (VRS). The sessions lasted 10.5 min each (with a work-to-rest ratio of 90:90 s). Baseline, inter-stimulus, and post-exercise measurements were taken for the Feeling Scale (FS). Inter-stimulus and post-exercise measurements were also taken for Cognitive Load (CL) and Rating of Perceived Exertion (RPE). Post-exercise measurements were performed for Self-efficacy (SE), Future Intention (FI), and System Usability Scale (SUS). Percentage of Maximum Heart Rate (%HRmax) achieved during rest and exercise was established.

Results

showed no significant intra- or inter-group differences for FS, CL, or RPE, and no inter-group differences for SE, FI, or SUS (p > 0.05). Participants experienced low CL and high levels of FS, SE, FI, and SUS. Additionally, session intensity was classified as "very, very easy" to "easy" (RPE) and "very light" to "light" (%HRmax).

Conclusion

The smart walker-assisted gait session in an immersive VR scenario favored participants' ARs, demonstrating promise for enhancing elderly engagement.
