碩士 / 大同大學 / 資訊工程學系(所) / 97 / There has been increased interest in navigational services for pedestrians in recent years. It is necessary to understand the information requirements of users and examine the information for how it is presented accordingly when they interact with navigation systems in pedestrian situation. When interacting with existing navigation services, the visual display is often inappropriate. There are significant problems associated with user attention and cognitive load, when using a mobile device in pedestrian situations while user should pay attention to peripheral information which they are interested or care about, rather than the small mobile screen.
In this paper beginning, we use ambient display to present pedestrian navigation information. We studied the user experience of interacting with navigation services in pedestrian situation. We chose tactile interface as a calm feedback to present abstract navigation information. Two experiments were designed to investigate whether using tactile display to preset navigation information is sufficient and appropriate in pedestrian situation. In the first experiment, we used two tactile parameters to construct the abstract navigation information of the existing navigation services. In the second experiment, we verified that the abstract navigation information could guide the users to their desired target location via continuous tactile feedback. The result of those experiments showed that Tactons could be a successful means of communicating navigation information in user interfaces in pedestrian situations.
Finally, we use Google Map API, PTK, and Tacton Toolkit to make our pedestrian navigation system. We use Google Map API to make destination input interface and path planning. We apply PTK to abstract navigation information and set information importance. We implement Tacton Toolkit and use Tacton Toolkit to help us transforms abstracted navigation information and information importance into Tacton. We present tacton to the user by the mobile device. When our system is presenting navigation information, User has to distinguish the tacton parameter to gain the navigation information. The final experiment confirmed that our pedestrian navigation system have ability to guide user to the destination easily.
In the future work, we will use mobile ambient display to implement the other mobile applications to meet user requirements.
