Ageing-appropriate adaptive electrotactile touch user interfaces in a translatory application

在消费品和工业产品领域，功能和视听指标有所增加，而物理控制要素有所减少。在对触摸屏的直接和直观操作的基础上，人类最基本的感觉之一触觉知觉在很大程度上被忽视了。关于技术产品的信息目前几乎完全以视听方式传播，尽管还有其他未使用的感知渠道。结果，用户被迫处理越来越复杂的用户-机器操作方式，最终导致感知和信息处理能力过载。由于随着年龄的增长，感知和认知能力的丧失越来越多，这就导致了过载过程的加速。在这个研究项目中，我们研究了触觉感知通道在机器操作过程中作为年龄函数的潜在救济能力。本研究项目的重点是设计一个电触觉触摸用户界面，作为年龄和感觉运动性能的函数。考虑到不断增加的信息流，本研究项目确定了电触觉触摸用户界面功能编码的必要和尚未存在的发现。通过多模态信息传递的方式来支持触觉信息传递，从而缓解视觉感知通道，特别是老年人的视觉感知通道。通过实验研究找出缺失的设计参数，根据用户的年龄和感知限制优化人机交互，保证更舒适、高效、有效的人机交互。

In the field of consumer and industrial goods, there is an increase in functions and audiovisual indicators with a reduction in physical control elements. On the basis of the direct and intuitive manipulation of touch screens, one of the most basic senses of the human being, the haptic perception, is largely neglected. Information about technical products is currently almost exclusively transmitted audiovisually, although other unused channels of perception are available. As a consequence the user is forced to deal with a steadily more complex way of user-machine operation which finally leads to an overload of perceptional and informatory processing capacity. Because of the increasing loss of perceptional and cognitive performance with age it comes to accelerated overload processes.In this research project, the haptic perception channel is examined for its potential relief capacity during machine operation as a function of age. This research project focuses on the design of an electrotactile touch user interface as a function of age and sensorimotor performance. The necessary and not yet existing findings for the function coding of an electrotactile touch user interface are determined in the present research project taking into account the ever increasing flow of information. The visual perception channel, in particular of older people, should be relieved by supporting tactile information transmission by means of multimodal information transmission. Missing design parameters are specified through experimental research aiming at the optimization of human-machine interaction according to the user's age and perceptional limitation to ensure a more comfortable, efficient and effective human-machine interaction.
