Abstract
The number of wireless phone products continues to grow at a very rapid pace. Likewise, competition among small-format operating systems and among hardware vendors has produced a variety of hand-held, business-information-oriented devices known generically as personal digital assistants, or PDA's. In the last several years, there has been a movement toward the convergence of wireless phone and PDA technologies. Such combined products have the advantages of the cell phone's wireless communication capabilities and the PDA's larger display and integrated address/email/internet functions. This manuscript describes the authors' work in developing a new operating system user interface framework for the next generation of one-quarter VGA (QVGA) integrated phone/PDA (communicator) products, as well as the functional UI for the telephone portion of the UI for a new QVGA device.
