Abstract

Content developers author Web content that is both appropriate for a desktop machine having a mouse and a keyboard and for client devices having alternative user input hardware. This content is capable of being received by the client browser and interpreted according to the local user input capabilities, whether they be a standard keyboard and mouse, numeric keypad, pen, or other input device.
