Understanding and supporting modality choices
Anthony Jameson, Per Ola Kristensson · ACM eBooks · 2017
One of the characteristic benefits of multimodal-multisensor processing is that it gives users more freedom of choice than they would otherwise have. The most central type of choice concerns the use of input modalities: When performing a particular task with a multimodal system, a user will often have a set of two or more input modalities to choose from. She may choose to employ just one of these; or she may use two or more modalities simultaneously or in alternation. In general, we can say that she must somehow choose some combination of modalities from the available set.
