In order to ease the development of devices with visual and voice interfaces for PDAs and other handheld devices, the Multimodal Toolkit and Rational Application Developer can be used. By using these products one can minimize the skills and time needed for creating complicated programs that use XHTML+V(XHTML + VOICE) on compatible devices.
XHTML+V is a new technology, that combine XHTML and voice interfaces on small devices, like PDAs and tablets. It is accomplished by combining different web standards, such as ECMAScript, JavaScript,
The Multimodal Toolkit adds extensions to Rational Application Developer to provide multimodal functionality, allowing the development of applications with both visual and voice user interfaces. The Toolkit provides an integrated development environment that can minimize both the skills and time needed to develop applications for XHTML+Voice aware PDAs and other handheld wireless devices.
XHTML+Voice (X+V) is a Web markup language for developing multimodal applications for wireless devices. X+V uses both voice and visual elements of user interaction.
The W3C Multimodal Interaction Activity is developing specifications as a basis for a new breed of Web application with multiple modes of interaction. Consider applications which use speech, hand writing, and key presses for input, and spoken prompts, audio and visual displays for output. It is implemented by several drafts, which we will briefly review in this article. These include InkML, a language that serves as the data exchange format for representing ink entered with an electronic pen or stylus; and EMMA, a data exchange format for representing
