Negative Feedback Control

Recent years have seen an explosion in the availability of Voice User Interfaces. However, user surveys suggest that there are issues with respect to usability, and it has been hypothesised that contemporary voice-enabled systems are missing crucial behaviours relating to user engagement and vocal interactivity. However, it is well established that such ostensive behaviours are ubiquitous in the animal kingdom, and that vocalisation provides a means through which interaction may be coordinated and managed between individuals and within groups. Hence, this paper reports results from a study aimed at identifying generic mechanisms that might underpin coordinated collective vocal behaviour with a particular focus on closed-loop negative-feedback control as a powerful regulatory process. A computer-based real-time simulation of vocal interactivity is described which has provided a number of insights, including the enumeration of a number of key control variables that may be worthy of further investigation.

This paper studies the usability methodologies for spoken dialogue web interfaces along with the appropriate designer-needs analysis. The work unfolds a theoretical perspective to the methods that are extensively used and provides a framework description for creating and testing usable content and applications for conversational interfaces. The main concerns include the design issues for usability testing and evaluation during the development lifecycle, the basic customer experience metrics and the problems that arise after the deployment of real-life systems. Through the discussion of the evaluation and testing methods, this paper argues on the importance and the potential of wizard-based functional assessment and usability testing for deployed systems, presenting an appropriate environment as part of an integrated development framework.
