Research Themes

The group studies speech-based human-computer interaction in mobile and ubiquitous computing environments. Work is carried out in several research projects by implementing prototype applications.

Modalities: Audio and Speech Interfaces

The group studies audio and speech-based human-computer interaction. The main focus is on interaction models, techniques and architectures. Topics include adaptive speech inputs and outputs, error handling strategies, dialogue management strategies, issues found in multilingual applications, gathering and fusion of multisensory and multimodal information, information representation in distributed applications and the use of ambient media in environmental interfaces.

Context: Mobile and Ubiquitous Computing, Special User Groups

The research focuses on ubiquitous and mobile environments. The group studies interaction techniques which supports both human-to-human and human-to-computer communication. Research themes include context-awareness, adaptivity, privacy and trust issues. Special user groups, such as visually impaired users are on special focus. The group works in collaboration with several such groups. The group has also experience on telephony applications.

Constructive research: Architectures and Applications

The Group has developed Jaspis, a general architecture for speech applications. The agent-based architecture of Jaspis has designed adaptive and multilingual applications in mind. The focus of current research is on the support of mobile and ubiquitous applications, multimodal inputs and outputs and more natural and flexible interaction models.

The group has constructed several applications on top of Jaspis, such as an e-mail application Postimies (Mailman) and Ovimies (the Doorman), a system that serves the visitors and staff members in TAUCHI premises.
