Human-machine Interface System Based on Electro-oculography ...

An environment-stable hydrogel with skin-matchable performance for human-machine interface

第一届国际测量仪器与测试自动化学术会议

作者： Li Jiansong Zhang Hongyu Mei Shaochun (Nanjing Univ. of Posts&Tecommunications Jiangsu Province 210003 China)

＜正＞In this paper we introduce a novel human-machine interface based on EOG（electro-oculogram） signal and head movement signal .Via this new brain-computer interacting technique, the subject could control the PC input device through the eyes’ movement instead of the hand. The EOG signal and head-movement compensative signal are abstracted by the data acquisition module, and in turn sent to the data analysis module depending on a wireless module. After processing, the signal is transferred to the eye tracing information and recruited to control the computer system. We adopted the head-movement compensation system and the wireless data module for the first time, significantly increased the portability and practicability of this system.

human-machine interface in agricultural machinery cab was defined as the interactive area among the driver and the driving cab components in this paper, which plays a significant role in farming, for it has effect on not only drivers’ working efficiency, but also their safety and health. Here, as the representative agricultural machinery cab, the driving components in tractor cab were analyzed, and then the hierarchy system for evaluating the human-machine interface in tractor cab was put forward. Applying the analytical method named analytical hierarchy process (AHP), the questionnaires from twenty-one occupational tractor drivers were analyzed, and the weight of each evaluating index in the hierarchy system was obtained. The results showed that the hand controllers and the visual components in the driving cab performed higher weights than the others, and the position of the cab components affects drivers more seriously than its size commonly. This research was the basic work for evaluating human-machine interface in agricultural machinery cab. In addition, the results could be referenced by the designers in agricultural machinery corporation or institution.

离子导电水凝胶由于其在生物相容性、导电性和灵活性方面的独特优势,已成为可穿戴式人体运动检测传感器的最有希望的替代品之一.然而,目前的水凝胶电子器件仍然面临着不可重复使用性和单一信号检测功能的限制.在此,我们通过模拟生物体的网络结构和离子传导机制,制备了基于聚乙烯醇、海藻酸纤维和胶原蛋白的离子导电水凝胶,用于人体运动和电生理信号的双模式信号采集.通过海藻酸纤维和胶原蛋白的协同调节,水凝胶表现出类似皮肤的机械性能,具有低模量、高韧性和抗疲劳性,从而可以最大限度地提高水凝胶可穿戴传感器的穿着舒适度和运动检测能力.此外,具有与生物体相似离子传输行为的水凝胶导体可以用作表皮电极,收集包含重要人体生理信息的表皮电位.通过对可穿戴设备的合理设计和组装,水凝胶不仅可以连续、准确地识别全身运动信号,还可以采集肌电图、心电图等不同电生理信号.值得注意的是,这种基于非共价交联结构的水凝胶是完全可回收的,可以任意重组为新的电子器件,同时保持原有功能,提高水凝胶的可重复使用性,减少电子浪费.
