Multimodal output
Real life multimodal use Sequential: Exclusive
-Sequential use of modalities that are not linked together in the same task. For example, recording speech and then closing all the unnecessary windows with a mouse.
Sequential: Alternate
The use of modalities is sequential, but they are linked together in the same task. For example, pointing an object with a
mouse and giving a voice command to copy it.
Parallel: Concurrent
The use of modalities is parallel, but they are not linked together. Usually the hardest kind of multimodal systems, but may
result in a better efficiency with some training. For example, driving a car while speaking in a mobile phone
Parallel: Synergistic
The use of modalities is parallel and they are linked together. For example, pointing and speech command at the same time.
[Nigay and Coutaz]
Multimodal versus Multimedia
Multimodal systems use more than one sense/mode of interaction e.g. visual and aural senses: a text processor may speak the words as well as printing them to the screen
Multimedia systems use a number of different media to communicate information e.g. an e-learning system may use video, animation, text and still images and use speech and non-speech
Interaction with these systems The combination of human output
channels effectively increases the bandwidth of the human-machine channel (e.g., Oviatt, 1999)

Multimodal output
-Visual: Text, pictures, signs, color
-Audio: Verbal, non-verbal, signals
-Olfactory: Smell
-Haptic (combination of movement and tactile)
Signs

example
Multimodal interaction and multisenory feedback can exert significant cognitive demands on users. Attention is selective and has limited capacity. Short term memory also has limitations. Consider human ability when designing the interface, essential for control and learning affordances
