Multimodal Interfaces

The growing emphasis on multimodal interface design is fundamentally inspired by the aim to support natural, easy to learn and use, flexible, efficient, and powerfully expressive means of human-computer interaction. Most of the articles in this special issue present work in support of challenging applications such as algebra instruction, data summaries, and interaction with complex spatial displays. A collection of emerging research ideas on next-generation multimodal interfaces, it also addresses multimodal interface design for portable devices to be used in natural field settings. Additionally, it describes implemented systems that make computing accessible to the visually impaired.
