Tiivistelmä
Haptic feedback is an important element in the successful and safe operation of user interfaces of an elevator. A haptic feedback can be obtained from a number of technologies and mechanisms. European Standard EN 81-70:2018 defines the minimum criteria that a user interface device should meet in order to be used in an elevator. Haptic feedback is a vital requirement that a user interface should have, according to the EN 81-70:2018. This thesis is focused on the investigation of various technologies that can be used to obtain a haptic feedback in UI devices of an elevator. The objective was to identify a new haptic feedback enabled technology that can meet the requirements defined by EN 81-70:2018.
The research work started with the identification of the available new technologies through online resources. With the help of experts, those technologies were selected for further investigation, that were expected to meet the elevator industry standards. A triangulation technique was utilized with European standard EN 81-70:2018, literature and information from expert opinions, as the vertices of the triangle. The information on various technologies was obtained through literature study and expert opinions. The literature study yielded in an understanding of the features and capabilities of each technology. The expert opinion provided an industry-based view of the technologies under investigation. The thoughts of the experts were collected in semi structured interviews. These interviews led to the evaluation of the capability of each technology to meet the industry standards.
Various parameters were defined as the benchmarks for comparison of the selected technologies. These parameters were obtained from EN 81-70:2018 and from experts. The outcome of the research was that piezo electric devices are the most suitable modern mechanisms that can be used in the user interface devices of an elevator.
