Exploring Affective Computing: Emotions and Human-Computer Interaction

This project focuses on harnessing emotional intelligence in human-computer interaction (HCI) using various technologies such as eye tracking, EMG, and EEG. The research team, including experts in psychology and computer science, investigates how emotions are defined, measured, and integrated into computing systems to improve interactions. By implementing emotional processes, computers can exhibit more flexible, learnable, and emotionally responsive interfaces. This research aims to redefine efficiency and quality in user-computer interactions, ultimately enhancing user experience.

  1. Veikko SurakkaUniversity of Tampere,Department of Computer Sciences HCI-group (eyetracking, EMG, EEG)Tampere University HospitalCNF-unit(EEG, fMRI) Emotional computer why and how?

  2. People working with this project HCI-people • PsT Veikko Surakka • Fm Timo Partala • PsM Anne Aula • Fm Poika Isokoski • Psyk. yo Maria Jokiniemi • Psyk. yo Marko Illi Signal analysis people • Prof. Martti Juhola • Fil. yo Jouni Laakso

  3. Contents • Introduction • What are emotions? • Perceptually intelligent machines • Affective Computing • About the measurement • Demonstrations and proposals for NIT-course

  4. WHAT IS AN EMOTION? A reaction including following components • Brain activation • e.g. amygdala • Muscle activation • Face, voice • Emotional experience • Joy, sadness, etc. • Behavioral change • Approach/avoidance

  5. EMOTIONS AFFECT SIGNIFICANTLY TO HUMAN • Information precessing • Memory • Thinking • Health • Interaction • ALTOGETHER TO HUMAN RATIONAL BEHAVIOR

  6. AFFECTIVE COMPUTING, EMOTIONAL COMPUTER • Future generation flexible, learnable, and emotionally responsive user interfaces • These interfaces utilize, for example, ANS activation correlates (e.g. pupil size variation) and (e.g. electric brain potentials) of the user in connecting the user with the computer

  7. AFFECTIVE COMPUTING • It is thought that by implementing emotional processes in HCI computers could be able to same kind of rational behavior than humans • Then the computer would be able to real interaction • The interaction would be more efficient and of much better quality

  8. MEASUREMENT • Bioelectricity based measurement • Videotechnology based measurement • These can be measured in real time • These can also be analyzed almost in real time by the computer

  9. Grass Model 115 8-channel Neurodata Acquisition System

  10. ASL series 4000 eyetracking system Optiikka Ohjausyksikkö

  11. Two proposals • To improve the quality and flexibility of a system in which a computer agent can be driven by biosignals --- Demo • The further development of a visual analysis tool needed in basic research --- Demo
