The Ubiquitous Interactor - Device Independent Access to Mobile Services

TL;DR

The paper presents UBI, a system that enables device-independent access to mobile services by separating interaction logic from presentation, allowing tailored interfaces for various devices without increased development effort.

Contribution

It introduces a novel system design that separates interaction from presentation, facilitating device-independent service access and reducing development complexity.

Findings

Successfully implemented calendar and stockbroker services using UBI.

Demonstrated flexible, device-specific user interfaces without extra development.

Validated the approach's effectiveness for multi-device service access.

Abstract

The Ubiquitous Interactor (UBI) addresses the problems of design and development that arise around services that need to be accessed from many different devices. In UBI, the same service can present itself with different user interfaces on different devices. This is done by separating interaction between users and services from presentation. The interaction is kept the same for all devices, and different presentation information is provided for different devices. This way, tailored user interfaces for many different devices can be created without multiplying development and maintenance work. In this paper we describe the system design of UBI, the system implementation, and two services implemented for the system: a calendar service and a stockbroker service.
