Sažetak
The purpose of this study is the introduction of haptic feedback scenarios for Human-Machine-Interface (HMI) devices and concept development of actuator connections for achieving specific feedbacks similar to pushing a button icon commonly used on touch displays. The proposed design shows how haptics can restore tactile feedback to touch screens and improve the user interaction with machines. It is shown that haptic technology can reduce driver distraction and increase confidence within the vehicle by adding clear and fast response from touch elements in their infotainment center console. In particular, display and control elements in the automotive and consumer goods industry are getting more flexible in form of touch screens or simple sensor surfaces. Especially new interior concepts of vehicles are changing from multiple physical buttons to displays. This brings a huge disadvantage – the lack of feedback when actuating. The following chapters explain the basics of haptic technology and different types of feedback scenarios including alternatives to a click. Mostly used actuators will be represented with their advantages as well as disadvantages. Further, the main requirements and evaluation criteria will be stressed for choosing the most suitable actuator and the appropriate technical connecting concepts for possible implementations for a touch screen haptics solution. Using actuators which have short rising time is a key point when simulating realistic button click feedback. Taking the results into account a prototype was implemented. Some of the requirements included the position of the actuator, the display separation into critical components, necessary sealing elements and mounting options of the cover plate. A holder for the actuator was designed and the feedback was tested.
