In spite of affordability, portability, and convenience of mobile handheld devices, there are a number of usability problems associated with Web access through those devices, largely attributable to their inherent physical constraints. In the past decade, there have been increasing empirical studies on interface issues and usability of mobile handheld devices and mobile Web. However, researchers have been frequently using emulators of handheld devices running on desktop computers instead of real, physical handheld devices in those studies. Such a phenomenon raises validity and generalizability concerns given the differences between emulators and physical devices. This research empirically investigates whether the user performance and perception of mobile Web on an emulator is equivalent to or at least consistent with that on a physical device. The findings suggest that an emulator may not be able to emulate user performance and perception with physical handheld devices, and thus should be used with caution.

“…The usability of mobile devices and their applications is a key factor for the success of mobile computing. Betiol and Cybis [2] studied usability evaluation of mobile interfaces based on three different evaluation approaches; they mentioned the importance of the context of use of mobile devices in the usability evaluation, so that the traditional HCI evaluation criteria and methods should be reconsidered in order to meet the requirements of mobile interaction. There are now more browsers on mobile phones than on desktops, and there is a vast diversity in the types of devices; on top of this diversity, there is also the diversity required for accessibility [25].…”

“…The definition of usability for mobile devices was referred [2] from of ISO 9241-11: "The extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use." A system for automatically evaluating the usability and accessibility of Web sites by checking their HTML code against guidelines has been studied by Beirekdar et al [1]; they introduced the idea that "the general process of performing an automated evaluation of a Web site could be decomposed into the following sequence of four main steps:…”

Web-based information services should be evaluated for accessibility and usability with various types of Internet Web-browsing devices, interacting with web information servers including directory server. A ubiquitous name-based directory server, accessible and usable with a variety of Web-browsing devices (e.g. Internet-capable mobile phones), could be a unified center for human-centric Web interaction services as well as for business models based on personalized services. We studied the accessibility and usability in user-centric Web interaction with a unified-ubiquitous name-based directory service, as metric metadata for real-time estimation. We studied the real-time metrics in synthetic approach for comparison among different services. We show empirical results based on implementation and experiments in Korea, Japan and China.

“…The needs of the mobile user, the characteristics of the mobile applications, the usage context of the device and physical limitations of the device to be considered in designing the device as well as in performing usability evaluations of the device (Betiol & Cybis, 2005). The user can use mobile devices in different environments where he/she is not always stationery.…”

Together with the use of rapid prototyping techniques and efforts to reduce the production cost, wearable and mobile electronic devices brought to the market faster than ever, with less time spent on actual usability testing of these devices for prolonged use. Due to this, the usability lifespan of such electronic devices has reduced significantly where consumers might be moving or upgrading on to using newer electronic devices more often than they really need to. Therefore, this paper focuses on identifying key characteristics of usability that may encourage prolonged use of an activity-monitoring device. Secondary goal was to observe and record any user acceptance and/or usability issues that may arise from using an activity monitor over a prolonged period.In this research, an intensive study was undertaken using ethnographic methods of enquiry to improve the rigor of the study. In general, ethnography rests upon participant observation, a methodology whereby the researcher spends considerable time observing and interacting with a social group. The researcher analyzed the face-to-face interviews' video recordings and collected field notes repeatedly according to the coding rules devised using open-coding methodology. Later on, the researcher formed a generic thematic analysis based schema to analyze the coded data.
