Many devices can't use cookies to remember user details even though, in theory, WAP supports this technology. Instead use hidden form fields containing session identifiers, either in the header using the 'POST' method or in the URL using the 'GET' method, for better session management. Don't use numerous introduction screens and reduce the number of clicks to a minimum that a person needs to use to get to the information they require or to perform their task. Consider combining voice-recognition technology with data input. Remember though that users like privacy and may feel restrained or restricted from using their voice due to high noise levels or too much proximity to other people.
Many wireless applications have little or no navigation.
Despite technological restrictions it is possible to use it. Keep navigation style and placement consistent throughout the application. Use arrows and step numbers to manage user expectations if continued scrolling or click-throughs are required to gain further information for task fulfillment. Use wireless to beat your competition, improve your working environment internally and embrace your users 24 hours a day. Ultimately, you can use wireless to give your customers something they can't live without.
