We observed an overall good usability level.
This study aims to determine the usability level of University web site on the Internet environment respect with "learnability, effectiveness, efficiency and satisfaction".
The output of this research is an accurate user interface that represents a conceptual design and a guide to create a high usability level of content and interface of SPIN.
Also, as users are already familiar with this kind of devices, the usability level achieved could be improved, although, as it will be mentioned below, mobility also creates new usability challenges.
Our outcomes indicate that the usability levels retrieved from task-based evaluation are not directly linked to integration of boundary documents into the governmental websites.

The investigation found that most of users were emotionally attached to usability (behavioural level) and appearance (visceral level) of their products that are easily replaced.
The research indicated that many people, including designers and manufacturers, are unconsciously focusing on usability (behavioural level) and physical look (visceral level) of a product that are easily replaced, than on a meaningful way (reflective level) to create and maintain long-lasting emotions.
The design experiments addressed the notion of 'unusable and broken products'; and, asked the question, can accessing usability (behavioural level) and embracing imperfection/impermanence of the found materials (visceral level) give meaning of mortality (reflective level) to category one (undesirable) furniture's?
As a result, the proposed evaluation framework enabled the measurement of the mobile phone usability risk level in the early stages of the concept design.
The lack of usability (behavioural level) can be repaired and improved.
