- Does the New Input Mode Add Value to the Web Application?
- Does the Application Leverage the Strengths of the New Mode and Avoid Its Weaknesses?
- Does the User Have Access to the Required Hardware and Software Required by the New Mode?
- Where Will Multimodal Applications Be Used?
Does the User Have Access to the Required Hardware and Software Required by the New Mode?
Most telephones do not have full QWERTY keyboards, so they cannot be used for typing alphabetic data. Many PCs do not have high-quality microphones used for speech recognition. Most PDAs do not have microphones at all. 3G phone devices promise to have the communication bandwidth to support multimodal applications, but they are slow to appear in the marketplace.
It does no good to enable your application to support a mode if users cannot use the mode because of hardware limitations.
