Mobile computing is becoming one of the most widely adopted
technologies. There are 1.3 billion mobile phone subscribers
worldwide, and the current generation of phones offers substantial
computing ability. Furthermore, mobile devices are increasingly
becoming integrated into everyday life. With the huge popularity in
mobile computing, it is critical that we examine the human-computer
interaction issues for these devices and explicitly explore supporting
everyday activities. In particular, one very common and important
activity of daily life I am interested in supporting is
conversation. 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 to
enter information into a mobile computer in conversational situations.
First I examine the Twiddler, a keyboard that has been adopted by the
wearable computing community. The Twiddler is a mobile one-handed
chording keyboard with a keypad similar to a mobile phone. The second
input method is dual-purpose speech, a technique designed to leverage
a user's conversational speech. A dual-purpose speech interaction is
one where speech serves two roles; it is socially appropriate and
meaningful in the context of a human-to-human conversation and
provides useful input to a computer. A dual-purpose speech application
listens to one side of a conversation and provides beneficial services
to the user. Together these input methods provide a user the ability
to enter information while engaged in conversation in a mobile
setting.
