The advancement of ubiquitous systems which focuses more on how it interacts with users to support their daily activities provides a new challenge in assessing the quality of the system. Its unique characteristics such as invisibility and context awareness make it more challenging to be mapped to a generic quality model to assess its usefulness. Therefore, this work aims to identify the quality characteristics and quality model to measure ubiquitous application. To achieve the aim, the systematic literature review will be conducted to identify quality characteristics of ubiquitous application and existing measures to assess the usability of these systems. Then, a usability measurement model will be designed and validated by experts through review sessions. The result will be an improved usability model for ubiquitous application which will provide a guide for researchers in evaluating ubiquitous systems using the improved model designed specifically for ubiquitous systems.
