| Research Abstract |
This research project has investigated design of human interface to support human-machine collaborations under dynamically changing environment in which allotted time. may be limited for situation recognition, decision making, and action selection and implementation. Function allocation needs to be dynamic and situation-adaptive to support humans appropriately. Machines have thus been given various types of intelligence. Intelligent machines can now sense and analyze situations, decide what must be done, and implement control actions. It is true, however, humans working with such smart machines often suffer negative consequences of automation, such as the out-of-the-loop performance problem, loss of situation awareness, complacency or over-trust, and automation-induced surprises. By taking the adaptive cruise control (ACC) system as a real-world example of adaptive systems, this research project has developed the concept of multi-layered human interface in which information is provided with human drivers so that they can share situation recognition and intentions with automated systems and authority may be traded dynamically in an emergency to assure system safety. The efficacy of the human interface has been analyzed and evaluated through series of cognitive experiments with various types of scenarios. Furthermore, computer simulation methods have been developed to investigate degree of safety degradation due to drivers' over-trust in automation, in which conventional cognitive experimental approach may not be applicable or feasible. It has been proven that an effective strategy for function allocation between humans and automation assuring system safety can lie within the category that does not fulfill conditions assumed for a conventional human-centered automation.
