Humans interact with the world using
multiple MODALITIES
Visual: e.g. colors, perspective
Aural: sounds and effects
Gestural: body, gestures, emotions
Spatial: architectural, geographic
Linguistic: vocabulary, metaphors
What is Multimodality?

Multimodality in Human Interactions
Communication is a two-way process:
– Encoding messagesusing multiple modalities like textual,
linguistic, spatial (Kress, 2003)
– Decoding messages capturing through the senses and
reasoning about them (Paivio, 1990).

Multimodality for computers
e.g. 3D visualisations in AR
They decode
sensor inputs
e.g modern AR
headsets like
Hololenes
e.g. accelerometer, gaze direction
position in the room, light sensor

Final objective: Multimodal Tutors
Pagina 12
The vision is to create
intelligent tutoring systems
which fully understand the user …
… and can maximise objectives such as:
- learning gains
- collaboration
- skill mastery
- knowledge acquisition
- behavioral change ….

1. Corrective feedback: hardcoded rules e.g. “if sensor value is x then y”; (non-adaptive)
2. Predictions: estimation of the learning labels (adaptive)
3. Pattern identification mining of recurrent sensor values
4. Historical reports: visualizations and analytics dashboard
5. Diagnostic analysis of factors
6. Comparison (e.g. Expert vs Learner)
