“…The notion of an audio window system was introduced by Cohen and Ludwig [7]. Cohen also introduced the concept of using 3D sound to increase the auditory display space and proposed simple gestural interaction with 3D sound for input [6]. According to Cohen, sounds are positioned in the space around the user and a mapping between the sounds and the elements of the interface is performed.…”

The study reported here investigates the design and evaluation of a gesturecontrolled, spatially-arranged auditory user interface for a mobile computer. Such an interface may provide a solution to the problem of limited screen space in handheld devices and lead to an effective interface for mobile/eyes-free computing. To better understand how we might design such an interface, our study compared three potential interaction techniques: head nodding, pointing with a finger and pointing on a touch tablet to select an item in exocentric 3D audio space. The effects of sound direction and interaction technique on the browsing and selection process were analyzed. An estimate of the size of the minimum selection area that would allow efficient 3D sound selection is provided for each interaction technique. Browsing using the touch screen was found to be more accurate than the other two techniques, but participants found it significantly harder to use.

“…MAW is intended to interpolate between conventional telephony and VR (Cohen, 1993b), but it can only suggest real acoustic environments. Its major simplification is the use of only 2 1 2 spatial dimensions, which seems to be more of a liability for musical expression than for teleconferences (as people in real conferences tend not to exploit the vertical dimension anyway, with the significant exception of addresses from a stage).…”

Audio windowing is a front-end, or user interface, to an audio system with a real-time spatial sound back end. Complementing directionalization by a digital signal processor (DSP), gain adjustment is used to control the volume of the various mixels ({sound} mixing elements). Virtual gain can be synthesized from components derived from collective iconic size, mutual distance, orientation and directivity, and selectively enabled according to room-wise partitioning of sources across sinks. This paper describes a derivation of virtual gain, and outlines the deployment of these expressions in an audio windowing system.

“…Feedback is given using perceptual operators that slightly change sounds as a result of a signal transformation. According to Cohen 'the idea is to create a just noticeable difference', an acoustic enhancement that is noticeable but ignorable, unambiguous but unintrusive' [4]. Such feedback can be provided by filtering, echoes, reverberation or equalization.…”

We present the results of an empirical study investigating the effect of feedback, mobility and index of difficulty on a deictic spatial audio target acquisition task in the horizontal plane in front of a user. With audio feedback, spatial audio display elements are found to enable usable deictic interaction that can be described using Fitts law. Feedback does not affect perceived workload or preferred walking speed compared to interaction without feedback. Mobility is found to degrade interaction speed and accuracy by 20%. Participants were able to perform deictic spatial audio target acquisition when mobile while walking at 73% of their preferred walking speed. The proposed feedback design is examined in detail and the effects of variable target widths are quantified. Deictic interaction with a spatial audio display is found to be a feasible solution for future interface designs.
