This paper reports on the in-context evaluation of an audio-tactile interactive tourist guide - one test was done in a medieval city center, and the other was done at an archaeological site. The activity theory framework was used as a perspective to guide design, field-study and analysis. The evaluation shows that the guide allows users to experience an(More)
People who have visual impairments may have difficulties navigating freely and without personal assistance, and some are even afraid to go out alone. Current navigation devices with non-visual feedback are quite expensive, few, and are in general focused on routing and target finding. We have developed a test prototype application running on the Android(More)
One factor which can be expected to influence performance in applications where the user points a device in some direction to obtain information is the angle interval in which the user gets feedback. The present study was performed in order to get a better understanding of the influence of this angle interval on navigation performance, gestures and(More)
In the present paper we report on the design decisions and the field test results of an inclusive mobile tourist guide app, the Time Machine. The historical information is conveyed by sound and the navigation information by haptics, while the app can be controlled eyes-free by a combination of on-screen and free-form gestures. To emphasize the eyes-free(More)
The present study was performed in order to get a better understanding of the influence of the scanning angle interval on navigation performance, gestures and strategies in a more realistic outdoor setting. Results indicate that users are able to handle a wide range of angle intervals. We observe different gestures and strategies and provide recommendations(More)
This paper describes the vibrationnal feedback that was chosen for the guiding interaction part of the Lund Time Machine application. This tourist guide provides information on points of interests along a trail, and guides the user along it. The interface uses audio and tactile modalities to be accessible in situations where the visual channel is not(More)
In the present paper we describe an inclusive tourist application, The Time Machine, that allows users to explore an environment or be guided along a trail while experiencing virtual sounds and get information (visual and auditory) at key locations in the environment. We report the application design and preliminary results from evaluations in a city(More)
An audio-tactile interactive tourist guide is demonstrated, including the possibility to be guided to points of interest. In contrast with the key-hole like experience of on-screen augmented reality, this guide makes use of the non-visual modalities to create a more immersive augmented experience. Sound windows from the past and verbal historical(More)
This article deals with a method for interacting with a handheld navigation application, based on using the mobile device for pointing. When the user points the device in any direction, feedback will be provided based on if the user is aiming at the next point in the track or beside it. The presented study has been performed in order to get a better(More)
Neurological patients with symptoms of Apraxia and Action Disorganisation Syndrome commit cognitive errors during everyday goal-oriented tasks which premorbidly they used to perform automatically. CogWatch is a new cognitive rehabilitation system under development which uses instrumented objects, ambient and wearable sensors to monitor patients behavior and(More)
