DT2140 Multimodal Interaction and Interfaces 7.5 credits

Humans are using multimodality extensively to communicate with each other, either simultaneously (in face-to-face conversations) or alternatively (using speech, writing, gestures, touch). The communication with computers has on the other hand traditionally employed few modalities: the user provides input with keyboard or mouse and the computer responds visually, in the form of text or icons.

This course gives an introduction to new interfaces that can improve the experience or the efficiency of the interaction with computers (such as voice control, sound interaction, gesture recognition, touch screens, haptic feedback, augmented reality).

Content and learning outcomes

Course contents

The course gives the students theoretical and practical introductions to multi-modal communication and different HCI techniques.

The main focus of the course is on technologies for the transfer of information

- from the user, such as speech recognition, touch screens or tracking of eyes and gestures, and

- from the computer, such as unconventional visual representations, speech synthesis, rendered sounds and haptic feedback.

Particularly, the effects of combining different modalities are considered.

Intended learning outcomes

After passing the course, the student should be able to:

  • describe how alternative or multi-modal HCI interfaces work, that utilise the latest technology
  • evaluate strengths and weaknesses of multi-modal interfaces
  • implement HCI interfaces that use new interaction technologies, for limited tasks
  • suggest efficient design solutions for new interfaces that use different modalities

in order to be able to

  • deepen her/his knowledge of new modalities of interaction in advanced courses
  • exploit multimodality in applied projects
  • choose an appropriate interface for a given task, from HCI and technical perspectives.

Ethical approach

  • All members of a group are responsible for the group's work.
  • In any assessment, every student shall honestly disclose any help received and sources used.
  • In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
