“…The use of icons to replace textual information is now standard practice and particularly useful for small hand-held devices [21,24,34]. The design of an icon can be based either on the recognizable picture of a real object-such as a telephone or printer-or can be based on the simplified version of a previous icon.…”

In Usability and Accessibility Engineering, metric standards are vital. However, the development of a set of reciprocal metrics-which can serve as an extension of, and supplement to, current standards-becomes indispensable when the specific needs of end-user groups, such as the elderly and people with disabilities, are concerned. While ISO 9126 remains critical to the usability of a product, the needs of the elderly population are forcing the integration of other factors. Familiarity and recognisability are not relevant to someone with no experience and therefore no referent; however, acceptance becomes a major factor in their willingness to learn something new and this acceptance requires trust based on association. Readability and legibility are of less relevance to a blind person than to someone with failing eyesight. This paper describes some usability metrics ascertained on the basis of experiments made with applications for elderly people throughout the summer term of 2007. The factors that influence the older users' acceptance of software, including the extent of their previous exposure to technology, are evaluated in order to provide short guidelines for software developers on how to design and develop software for the elderly. The evaluation of the expectations, behavior, abilities, and limitations of prospective end-users is considered of primary importance for the development of technology. A total of N = 31 participants (22 women/9 men) took part in various tests. The participants' ages ranged from 49 to 96 years with an average age of 79. Five of the tests were designed for a PDA or cellular phone, one test was designed for a laptop PC. Of the total of 55 tests, 52 tests provided sufficient data to evaluate the results. In 23 of the tests, all tasks were completed. As a main outcome, it can be experimentally proved that the acceptance is related to a factor, which is this paper is called PET (Previous Exposure to Technology). This is discussed in light of the aforementioned metrics.Most usability engineering is qualitative: we observe how end users use an application, what they like and what they hate, and if it is really bad we want to change it … if the developers have time [33].

“…Again, with a mobile phone, the task of ensuring information security should not be overlooked. Nischelwitzer et al [2007] focused on usability for the elderly people, while developing a distributed medical application for chronic disease care in a home environment. The application allows patients to use a Flash-based smartphone client or a standard Web client to enter medical data, including blood pressure, blood glucose levels, and peak flow.…”

Chronic medical conditions take a huge toll on lives of a growing number of people and are a major contributor to the rising costs in healthcare. As patients are increasingly willing to take an active part in managing their conditions, chronic disease self-management programs and information systems that support them are recognized for their potential to improve the quality of healthcare delivery. These programs often rely on recording longitudinal patient data and analyzing it. Therefore, maintaining appropriate data quality is important for self-management programs to be efficient and safe. We designed and implemented a prototype of a health self-management service for chronically ill people. It is a distributed application that supports patients with diabetes at tracking their blood glucose levels. The main design goals were usability, extensibility, security, and interoperability. The system integrates with the Microsoft HealthVault and Google Health personal health record platforms. It utilizes industry-strength storage and security mechanisms, is scalable, and as a result, can be used to gather, securely store, and analyze patient data over long periods of time. In this article we examine how software information technology can support chronic disease self-management and its impact on the quality of patient data. Furthermore, we describe the requirements that drove the system's development, its architecture, and design decisions. ACM Reference Format:Sunyaev, A. and Chornyi, D. 2012.

“…Not all users age in the same way, and the onset of aging processes as well as the consequences show considerable differences across humans. Design approaches should therefore take the userperspective seriously [14,15,16,17]. This includes that adults' behavior with current technical devices is carefully studied and also, that user abilities are identified, which affect the interaction with interactive computing devices.…”

Technology acceptance has become a key concept for the successful rollout of technical devices. Though the concept is intensively studied for nearly 20 years now, still, many open questions remain. This especially applies to technology acceptance of older users, which are known to be very sensitive to suboptimal interfaces and show considerable reservations towards the usage of new technology. Mobile small screen technology increasingly penetrates health care and medical applications. This study investigates impacts of aging, technology expertise and domain knowledge on user interaction using the example of diabetes. For this purpose user effectiveness and efficiency have been measured on a simulated small screen device and related to user characteristics, showing that age and technology expertise have a big impact on usability of the device. Furthermore, impacts of user characteristics and success during the trial on acceptance of the device were surveyed and analyzed.
