【 摘 要 】

Mobile computing is becoming one of the most widely adoptedtechnologies. There are 1.3 billion mobile phone subscribersworldwide, and the current generation of phones offers substantialcomputing ability. Furthermore, mobile devices are increasinglybecoming integrated into everyday life. With the huge popularity inmobile computing, it is critical that we examine the human-computerinteraction issues for these devices and explicitly explore supportingeveryday activities. In particular, one very common and importantactivity of daily life I am interested in supporting isconversation. Depending on job type, office works can spend up to 85\%of their time in interpersonal communication.In this work, I present two methods that improve a user's ability toenter information into a mobile computer in conversational situations.First I examine the Twiddler, a keyboard that has been adopted by thewearable computing community. The Twiddler is a mobile one-handedchording keyboard with a keypad similar to a mobile phone. The secondinput method is dual-purpose speech, a technique designed to leveragea user's conversational speech. A dual-purpose speech interaction isone where speech serves two roles; it is socially appropriate andmeaningful in the context of a human-to-human conversation andprovides useful input to a computer. A dual-purpose speech applicationlistens to one side of a conversation and provides beneficial servicesto the user. Together these input methods provide a user the abilityto enter information while engaged in conversation in a mobilesetting.
