Our MMIG group looks at all aspects of multimodal HCI (Human-Computer Interaction). With multimodal interaction, we mean humans using machines via several senses. For instance, people can touch, feel, smell and hear computer outputs, and computers can decode how people speak, wave hands, or look at things.

Our group approaches research through analytic and constructive means. We build prototypes, study behavior of people, invent new technologies, carry out laboratory tests, and do generally crazy stuff.

Some of our research topics are listed below, together with a few key research questions.

Selected papers on these topics are found in the Publications section, and specific topics in the Projects section.

Utilizing modern user interaction technologies to enable users to have more efficient and natural interaction​. Research on multimodal (visual, auditory, haptic, scent) technologies for creating eating experiences that promote health and wellbeing.

Can restorative virtual environments replicating real natural environments such as forests bring therapeutic benefits?​

User behavior analysis and utilization​

Studying user behavior in basic multimodal interaction task​, such as improving speed and accuracy of pointing with good quality feedback, using haptics and other technologies​. Studying timing requirements​. Experimenting with new uses of existing techniques for user interaction, such as analyzing gaze data to disambiguate intent, to improve accuracy in pointing​. Categorizing the user context to streamline the interaction​.

How much do we know about what the user is trying to achieve?​

Haptic Signal Mediation

Developing new technique to monitor and regulate how actuation signals are mediated from the source (actuation mechanism) to the point of (skin) contact. Identifying and enhancing actuation signals within an interaction system to actively remove environmental noise and other inefficiencies found in conventional actuation devices, ensuring the intended signal reaches the point of contact with minimum attenuation or interference.

Haptic Mediation: “A process of effectively relaying the actuation signal from the source (actuator) to the necessary point of contact (respective area of the skin), mitigating environmental noise and other internal and external inefficiencies within the system.” From: Farooq, 2017

Developing Novel Actuation Technologies

Designing and fabricating novel actuation components to provide more efficient multimodal systems. Fundamental research focused on creating a new generation of efficient actuation components that are targeted towards greater energy transfer as compared to replicating existing physical parameters (i.e. acceleration, displacement, frequency), which are outside human perceptual threshold.
