In this paper, we discuss investigations conducted with 10 visually challenged users (VCUs) and 8 sighted users (SUs) that aimed to determine user's experience, interest and expectations from concurrent information communication systems. In the first study, we concurrently played two voice-based streams in continuous form in both the ears, and in the second study, we concurrently communicated one stream continuously in one ear and three news headlines as interval-based short interruptions in another ear. We first reported the participants' experience qualitatively and then based on the feedback received from the users, we proposed a framework that may help in developing systems to communicate multiple voice-based information to the users. It is expected that the application of this new framework to information systems that provide multiple concurrent communication will provide a better user experience for users subject to their contextual and perceptual needs and limitations.

© 2018 Association for Computing Machinery. Speech-based information is usually communicated to users in a sequential manner, but users are capable of obtaining information from multiple voices concurrently. This fact implies that the sequential approach is possibly under-utilizing human perception capabilities to some extent and restricting users to perform optimally in an immersive environment. This paper reports on an experiment that aimed to test different speech-based designs for concurrent information communication. Two audio streams from two types of content were played concurrently to 34 users, in both a continuous or intermittent form, with the manipulation of a variety of spatial configurations (i.e. Diotic, Diotic-Monotic, and Dichotic). In total, 12 concurrent speech-based design configurations were tested with each user. The results showed that the concurrent speech-based information designs involving intermittent form and the spatial difference in information streams produce comprehensibility equal to the level achieved in sequential information communication.

This paper reports a study conducted with 10 blind and 8 sighted participants using a prototype system for communicating multiple information streams concurrently, using two methods of presentation. The prototype system in method one played two continuous voice-based articles diotically, differing by voice gender and content. In the second method, prototype communicated one continuous article in the female voice and three headlines as interval-based short interruptions in a male voice dichotically. In this investigation the continuous method remained more effective in communicating multiple information compared to the interval-based interruption method, and also the users who possessed at least tertiary qualification performed better in comprehending the multiple concurrent information than the non-tertiary qualified users.
