Navigation services can be found in different situations and contexts: while connected to the web through a desktop PC, in cars, and more recently on PDAs while on foot. These services are usually well designed for their specific purpose, but fail to work in other situations. In this paper we present an approach that connects a variety of specialized user(More)
Mobile and outdoor environments have long been out of reach for speech engines due to the performance limitations that were associated with portable devices, and the difficulties of processing speech in high-noise areas. This paper outlines an architecture for increasing speech recognition rates in a mobile pedestrian indoor/outdoor navigation environment,(More)
Accompanying the rise of mobile and pervasive computing, applications now need to adapt to their surrounding environments and provide users with information in the environment in an easy and natural manner. In this paper we describe a user interface that integrates multimodal input on a handheld device with external gestures performed with real world(More)
The increasing trend towards powerful mobile phones opens many possibilities for valuable personalised services to be available on the phone. Client-side personalisation for these services has important benets when connectivity to the cloud is restricted or unavailable. The user may also nd it desirable when they prefer that their user model be kept only on(More)
In this paper, we describe a near-complete Pocket PC implementation of a Mobile Multi-Modal Interaction (M3I) platform for pedestrian navigation. The platform is designed to easily support indoor and outdoor navigation tasks, and uses the combination of several modalities for presentation output and user input. Whereas 2D/3D-graphics and synthesized speech(More)
Normally, mobile pedestrian navigation systems use visually perceptible landmarks to guide their users through the environment. In this article we introduce concepts for the use of auditory perceptible landmarks in route descriptions. Such auditory perceptible landmarks complement their visual counterparts and also stand to be beneficial for certain groups(More)
This paper explores the nature of interfaces to support people in accessing their files at tabletop displays embedded in the environment. To do this, we designed a study comparing people's interaction with two very different classes of file system access interface: Focus, explicitly designed for tabletops, and the familiar hierarchical Windows Explorer. In(More)
Successfully conveying the interactivity of a Public Information Display (PID) can be the difference between a display that is used or not used by its audience. In this paper, we present an interactive PID called 'Cruiser Ribbon' that targets pedestrian traffic. We outline our interactive PID installation, the visual cues used to alert people of the(More)
