Non-Visual Menu Navigation: the Effect of an Audio-Tactile Display
نویسندگان
چکیده
We present a preliminary study examining non-visual menu navigation in terms of task completion times and cognitive workload. We asked 12 participants to locate items on menus presented using visual, audio-only and audio-tactile displays on a touch screen mobile device and found that users were significantly slower in locating an item on a menu when using an audio-tactile menu display. This difference in performance was not reflected in the users’ subjective workload assessments. We discuss the implications of these findings in terms of cross-modal display and the design of menu navigation gestures on touch screen devices.

Multimodal Threat Cueing in Simulated Combat Vehicle with Tactile Information Switching between Threat and Waypoint Indication
We investigated four display configurations for threat cueing in a simulated combat vehicle. The display configurations were a tactile belt only; the tactile belt combined with 3D audio; two visual displays combined with 3D audio; and a multimodal configuration (the visual displays, the tactile belt and 3D audio combined). The tactile display was also used for navigation information. The partic...
متن کاملCombining Speech and Earcons to Assist Menu Navigation
Previous research on non-speech audio interfaces has demonstrated that they can enhance performance on menu navigation tasks. Most of this work has focused on tasks in which the menu is not spoken and visual representation of the menu is accessible throughout the task. In this paper we explore the potential benefits that earcons, a type of structured sound, might bring to spoken menu systems fo...
متن کاملAudio Tactile Maps (ATM) System for Environmental Exploration by Visually-impaired Individuals
Navigation within open and closed spaces requires analysis of a variety of acoustic, proprioceptive and tactile cues; a task that is well-developed in many visually-impaired individuals but for which sighted individuals rely almost entirely on vision. For the visually-impaired, the creation of a cognitive map of a space can be a long process for which the individual may repeat various paths num...
متن کاملNon-verbal Audio and Tactile Mobile Navigation A comparative evaluation of two novel prototypes
As typical turn by turn systems fail in several aspects to provide an engaging experience to pedestrians in urban environments, we investigate the potential of alternative interaction methods for navigation. We present a two-phase experiment, involving both audio and tactile navigation and discuss the collected evaluation data. Our findings show a positive reception of implicit navigation from ...
متن کاملMultimodal feedback for the acquisition of small targets.
This paper examines how multimodal feedback assists small-target acquisition in graphical user interfaces. All combinations of three feedback modes are analysed: non-speech audio; tactile; and pseudo-haptic "sticky" feedback. The tactile conditions used stimulation through vibration (rather than force-feedback), and the sticky conditions were implemented by dynamically reconfiguring mouse contr...
