Multimodel Devices

What is Multimodal Device?

Mutimodal technology is a future human machine interfaces that helps to improve Web Accessibility in various environment of users.

For example, these days we can access the Web using multiples devices including mobile phones, PDA, car navigation system and home appliances.

Multimodel is combine of an input and output methods such as keyboard and mouse and speech, pen, touch screen and gestures. However other modalities, such as pen-based input or haptic input/output may be used. This involves Multimodal user interfaces which are a research area in human-computer interaction (HCI).
Users will be able to provide input via speech, handwriting, motion or keystrokes, with output presented via displays, pre-recorded and synthetic speech, audio, and tactile mechanisms such as mobile phone vibrators and Braille strips. Application developers will be able to provide an effective user interface for whichever modes the user selects. To encourage rapid adoption, the same content can be designed for use on both old and new devices. The capability of possible multimodal access depends on the devices used.

For example, users of multimodal devices which include not only keypads but also touch panel, microphone and motion sensor can enjoy all the possible modalities, while users of devices with restricted capability prefer simpler and lighter modalities like keypads and voice.Extensibility to new modes of interaction is important, especially considered in the context of the current proliferation of types of sensor input, for example, in biometric identification and medical applications.

This provide clear links between the software elements and the physical device description. The software elements encompass information to differentiate between similar service offerings, for instance, supported file formats.
