A Unified Personal Web Assistant System Applied to Information Appliance Control

Abstract

The remote control in many universal information appliances nowadays is operated through Mobile or Web Communications. For relaxing the access constraints in enjoying information appliance services, we established an unified personal web assistant (UPWA) to remotely control and access information appliance services across Internet, wireless network, and telephone network. UPWA provides a unified access to the information appliance service control by integrating the access facilities used in wireless application protocol (WAP), public switched telephone network (PSTN), Mobile, and Web system platforms to save the system cost of maintenance. Because of the access constraints released, users can flexibly use personal computers (PC), telephone sets, or WAP handheld devices to access information appliance services anytime anywhere they like.
