Design and evaluation of prosody-based non-speech audio feedback for physical training application

Methodological support for the design of non-speech user interface sounds for human–computer interaction is still fairly scarce. To meet this challenge, this paper presents a sound design case which, as a practical design solution for a wrist-computer physical training application, outlines a prosody-based method for designing non-speech user interface sounds. The principles used in the design are based on nonverbal communicative functions of prosody in speech acts, exemplifying an interpersonal approach to sonic interaction design. The stages of the design process are justified with a theoretical analysis and three empirical sub-studies, which comprise production and recognition tasks involving four communicative functions. The final evaluation study indicates that the resulting sounds of the design process successfully served these functions. In all, this study suggests that prosody-based sound design provides widely applicable means to attribute meaningful, interaction-derived qualities to non-speech sounds for interactive applications.     

Affective speech interface in serious games for supporting therapy of mental disorders

We describe a novel design, implementation and evaluation of a speech interface, as part of a platform for the development of serious games. The speech interface consists of the speech recognition component and the emotion recognition from speech component. The speech interface relies on a platform designed and implemented to support the development of serious games, which supports cognitive-based treatment of patients with mental disorders. The implementation of the speech interface is based on the Olympus/RavenClaw framework. This framework has been extended for the needs of the specific serious games and the respective application domain, by integrating new components, such as emotion recognition from speech. The evaluation of the speech interface utilized purposely collected domain-specific dataset. The speech recognition experiments show that emotional speech moderately affects the performance of the speech interface. Furthermore, the emotion detectors demonstrated satisfying performance for the emotion states of interest, Anger and Boredom, and contributed towards successful modelling of the patient’s emotion status. The performance achieved for speech recognition and for the detection of the emotional states of interest was satisfactory. Recent evaluation of the serious games showed that the patients started to show new coping styles with negative emotions in normal stress life situations.

A usability study of multimodal input in an augmented reality environment

In this paper, we describe a user study evaluating the usability of an augmented reality (AR) multimodal interface (MMI). We have developed an AR MMI that combines free-hand gesture and speech input in a natural way using a multimodal fusion architecture. We describe the system architecture and present a study exploring the usability of the AR MMI compared with speech-only and 3D-hand-gesture-only interaction conditions. The interface was used in an AR application for selecting 3D virtual objects and changing their shape and color. For each interface condition, we measured task completion time, the number of user and system errors, and user satisfactions. We found that the MMI was more usable than the gesture-only interface conditions, and users felt that the MMI was more satisfying to use than the speech-only interface conditions; however, it was neither more effective nor more efficient than the speech-only interface. We discuss the implications of this research for designing AR MMI and outline directions for future work. The findings could also be used to help develop MMIs for a wider range of AR applications, for example, in AR navigation tasks, mobile AR interfaces, or AR game applications.
