Abstract: This paper presents a route guidance system for car owners to find their cars in parking garages. The presents system comprises a positioning-assisting subsystem and a car-finding mobile app. The positioning-assisting subsystem mainly uses the iBeacon technology for indoor positioning. The car-finding mobile app guides car owners to their cars based on a non-map navigation strategy. This study also designs a virtual coordinate system to support identifying the locations of parking spaces and iBeacon devices. We use Arduino and Android as the platforms to implement the proposed positioning-assisting subsystem and car-finding mobile app, respectively. We have also deployed the system in a parking garage in our campus for testing. Experimental results verify that our system can efficiently and correctly guide car owners to the parking spaces of their cars.
Abstract: Map is a powerful and convenient tool in helping us to
navigate to different places, but the use of indirect devices often
makes its usage cumbersome. This study intends to propose a new
map navigation dialogue that uses hand gesture. A set of dialogue
was developed from users’ perspective to provide users complete
freedom for panning, zooming, rotate, tilt and find direction
operations. A participatory design experiment was involved here
where one hand gesture and two hand gesture dialogues had been
analysed in the forms of hand gestures to develop a set of usable
dialogues. The major finding was that users prefer one-hand gesture
compared to two-hand gesture in map navigation.
