Question

Is multi-modality always a good thing? Justify your answer

Answer 1

Answer:

yes

Explanation:

modality is harmful but multi modality is not harmful

Answer 2

Answer:

The multi-modality interface process combines two or more user input models, such as pen, touch, physical gestures, speech, and gaze, in a coordinated manner with multimedia system output.

Explanation:

• Multimodal human-computer interaction is defined as "interaction with the virtual and physical world using natural ways of communication."
• This means that multimodal interaction allows for more natural and free communication between humans and automated systems in both input and output.
• Multimodal systems, in particular, can provide a flexible, efficient, and usable environment by allowing users to interact with the system using input modalities such as speech, handwriting, hand gesture, and gaze, as well as receive information from the system using output modalities such as speech synthesis, smart graphics, and other modalities that can be combined in the right way.
• Then a multimodal system has to recognize the inputs from the different modalities combining them according to temporal and contextual constraints to allow their interpretation.
• This process is known as multimodal fusion, and it is the object of several research works from the nineties to now.
• Naturalness and flexibility can produce more than one interpretation for each different modality (channel) and their simultaneous use, and they consequently can produce multimodal ambiguity.
• Imprecision, sounds, and other comparable conditions are the most common causes.
• Finally the system returns to the user outputs through the various modal channels (disaggregated) arranged according to consistent feedback (fission).
• Several approaches for resolving ambiguities have been proposed.
• The widespread usage of mobile devices, sensors, and web technologies can provide sufficient processing resources to handle the multimodal interaction's complexity.
• “Using the cloud to embed shared computing resources and address the complexity of multimodal interactions presents opportunities.
• In fact, cloud computing is shared, which can be dynamically and automatically provisioned and released.
• Enables the provision of scalable and configurable computing resources".

Hence, multi-modality is always a good thing.
