The increasing use of new communication technologies such as gaze, gesture or voice control in the consumer goods sector as well as in the capital goods sector enables an ever higher degree of freedom of interaction between man and machine. At the same time, an increase in functions and audiovisual displays can be seen with a reduction in physical actuators. Due to their direct, intuitive manipulation capabilities and high interface flexibility, these technologies are gaining wide acceptance. However, one of the most basic human senses, haptic perception, is largely neglected in these technologies. This leads to an increase in operating complexity, which in turn results in an overload of the human ability to perceive and process information, especially in safety-relevant situations. One reason for this is that information of technical products is almost exclusively transmitted audiovisually, although other unused perception channels are available. In this research project, the haptic perception channel is to be investigated with regard to its relief potential, especially taking into account the user's age, as this has been largely ignored in age-related research to date. The loss of perception occurring with age as well as the decrease of cognitive and sensorimotor performance shall be compensated by tactile feedback via ultrasonic waves during hand gesture operation. On the basis of 6 work packages (WP), information content that is currently transferred exclusively audiovisually will first be analyzed and tactile coding possibilities for a tactile slider will be derived, taking into account the cognitive and sensorimotor aging processes. In the context of two subject studies (WP 2), basic parameters as well as tactile coding possibilities for information transfer via tactile feedback will be analyzed in two experimental groups (old and young). In the following synthesis phase (WP 3), the tactile coding parameters are clustered with regard to their support effect and assigned to operating scenarios. These operating scenarios are evaluated in a concluding study (WP 4) in the vehicle ergonomics test bench of the IKTD. The test persons perform the setting task once with purely visual feedback and once with supporting tactile feedback. In WP 5, design guidelines are derived and formulated, taking into account the study results and the sensory and cognitive characteristics of the test groups, in order to record them for developers and designers. In the last work package (WP 6), the research results will then be published at national and international conferences.

在消费品部门以及资本货物部门中越来越多地使用新的通信技术，例如凝视、手势或语音控制，使得人与机器之间的交互自由度越来越高。与此同时，随着物理致动器的减少，可以看到功能和视听显示的增加。由于其直接、直观的操作能力和高度的界面灵活性，这些技术正在获得广泛的认可。然而，这些技术在很大程度上忽视了人类最基本的感官之一触觉感知。这导致操作复杂性的增加，这反过来又导致人类感知和处理信息的能力过载，特别是在安全相关的情况下。其中一个原因是，技术产品的信息几乎完全是通过视听方式传播的，尽管还有其他未使用的感知渠道。在这个研究项目中，触觉感知通道将被调查关于其救济潜力，特别是考虑到用户的年龄，因为这在很大程度上被忽略了与年龄有关的研究。随着年龄的增长而出现的感知丧失以及认知和感觉运动性能的下降，应通过手势操作过程中超声波的触觉反馈来补偿。在6个工作包（WP）的基础上，将首先分析目前仅以视听方式传输的信息内容，并考虑到认知和感觉运动老化过程，推导出触觉滑块的触觉编码可能性。在两项主题研究（WP 2）的背景下，将在两个实验组（老年人和年轻人）中分析通过触觉反馈进行信息传递的基本参数和触觉编码可能性。在接下来的合成阶段（WP 3）中，触觉编码参数关于其支持效果被聚类并且被分配给操作场景。在IKTD车辆人体工程学试验台的总结研究（WP 4）中对这些操作场景进行了评估。测试人员用纯视觉反馈执行设置任务一次，用辅助触觉反馈执行设置任务一次。在WP 5中，考虑到研究结果以及测试组的感官和认知特征，推导并制定了设计指南，以便为开发人员和设计师记录它们。在最后一个工作包（WP 6）中，研究结果将在国家和国际会议上发表。
