Auditory Perceptible Landmarks in Mobile Navigation
Jörg Baus, Rainer Wasinger, Ilhan Aslan, Antonio Krüger, Andreas Maier, Tim Schwartz
Proceedings of IUI 07 (to appear)
[ DOWNLOAD NOTE ]
show abstract
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 like the visually impaired
and the elderly.
Computer Assisted Navigation and the Acquisition of Route and Survey Knowledge

It describes an empirical study on spatial learning conducted in a real environment. In the study, incidental spatial learning during wayfinding using navigation assistance on a PDA computer is compared with learning during wayfinding using maps. Computer assisted navigation is varied with respect to additional spatial context information and modality of presentation.

In this paper we regard the navigation aid provided by mobile navigation systems in a real environment and the effects of these mobile assistants to the development of spatial knowledge. Therefore, we report on a user study concerning the acquisition of spatial knowledge. This study sets up on a former study described by Krüger and colleagues and sheds light on problems concerning the acquisition of survey knowledge while being navigated by a mobile handheld PC.

The Compass2008 project is a sino-german cooperation,
aiming at integrating advanced information technologies to create a hightech
information system that helps visitors to access location-sensitive
information services during the 2008 Olympic Games in their preferred
language, offering a variety of service-adaptive modalities available on the
mobile devices. In this paper, we demonstrate one of the COMPASS2008
services, the Smart Dining Service, to showcase the new interaction concepts
between multimodality, multilingual and location-sensitive information
search.

Parallel Presentations for Heterogenous User Groups - An Initial User Study

show abstract
Presentations on public information systems, like a large screen in a museum, usually cannot support heterogeneous user groups appropriately, since they offer just a single channel of information. In order to support these groups with mixed interests, a more complex presentation method needs to be used. The method proposed in this paper combines a large stationary presentation system with several Personal Digital Assistants (PDAs), one for each
user. In this way, it is possible to maximize the benefit the large system provides for all users, while the individual PDAs may also adapt to each user's preferences. The basic idea is to "overwrite" presentation parts on the large screen, which are of little interest to a particular user, with a personalized presentation on the PDA.
We performed an empirical study with adult participants to examine the overall performance of such a system (i.e. How well is the information delivered to the users and how high is the impact of the cognitive load?). The results show, that after an initial phase of getting used to the new presentation method, subjects' performance during parallel presentations was on par with performance during standard presentations. A crucial moment within these presentations
is whenever the user needs to switch his attentional focus from one device to another. We compared two different methods to warn the user of an upcoming device switch (a virtual character "jumping" from one device to another and an animated symbol) with a version, where we did not warn the users at all. Objective measures did not favour either method. However, subjective measures show a clear preference for the character version.
Decision-Theoretic Planning Meets User Requirements

show abstract
This paper reports on extensions to a decision-theoretic location-aware
shopping guide and on the results of user studies that have accompanied its development. On the basis of the results of an earlier user study in a mock-up of
a shopping mall, we implemented an improved version of the shopping guide.
A new user study with the improved system in a real shopping mall conrms in
a much more realistic setting the generally positive user attitudes found in the
earlier study. The new study also sheds further light on the usability issues raised
by the system, some of which can also arise with other mobile guides and recommenders. One such issue concerns desire of users to be able to understand and second-guess the system's recommendations. This requirement led to the development of an explanation component for the decision-theoretic guide, which was evaluated in a smaller follow-up study in the shopping mall.
