“…Specifically, this study was performed as a "laboratory evaluation," a very common technique [51] which is widely applied (47% alone, and 10% in combination with field studies) [52] and, in addition, it is three times less cost consuming than field evaluations [53]. The downside of laboratory evaluations is its lack of context (in terms of real usage and environmental influences) [53,54], only present in nearly 11% of the studies [52].…”

Nowadays, instant messaging applications (apps) are one of the most popular applications for mobile devices with millions of active users. However, mobile devices present hardware and software characteristics and limitations compared with personal computers. Hence, to address the usability issues of mobile apps, a specific methodology must be conducted. This paper shows the findings from a systematic analysis of these applications on iOS mobile platform that was conducted to identify some usability issues in mobile applications for instant messaging. The overall process includes a Keystroke-Level Modeling and a Mobile Heuristic Evaluation. In the same trend, we propose a set of guidelines for improving the usability of these apps. Based on our findings, this analysis will help in the future to create more effective mobile applications for instant messaging.

“…Several studies conclude that field studies and field evaluations are time-consuming and costly [18,26,30]. Kaikkonen et al report that studies showed that usability field-testing required double the time compared their lab testing [30], while Jambon et al found that their field tests required almost triple the time compared to lab tests [26].…”

Evaluation is considered one of the major cornerstones of human-computer interaction (HCI). During the last decade, several studies have discussed pros and cons of lab and field evaluations. Based on these discussions, we conduct a review to explore the past decade of mobile HCI research on field and lab evaluation, investigating responses in the literature to the "is it worth the hassle?" paper from 2004. We find that while our knowledge and experience with both lab and field studies have grown considerably, there is still no definite answer to the lab versus field question. In response we suggest that the real question is not if -but when and how -to go into the field. In response we suggest moving beyond usability evaluations, and to engage with field studies that are truly in-the-wild, and longitudinal.

Human access to the increasing amount of information and data plays an essential role for the professional level and also for everyday life. While information visualization has developed new and remarkable ways for visualizing data and enabling the exploration process, adaptive systems focus on users' behavior to tailor information for supporting the information acquisition process. Recent research on adaptive visualization shows promising ways of synthesizing these two complementary approaches and make use of the surpluses of both disciplines. The emerged methods and systems aim to increase the performance, acceptance, and user experience of graphical data representations for a broad range of users. Although the evaluation results of the recently proposed systems are promising, some important aspects of information visualization are not considered in the adaptation process. The visual adaptation is commonly limited to change either visual parameters or replace visualizations entirely. Further, no existing approach adapts the visualization based on data and user characteristics. Other limitations of existing approaches include the fact that the visualizations require training by experts in the field. VII VIIIFinally, I thank my loved ones -my wife Mariam, my son Kian, my brothers and parents for their unlimited support, love, and patience.
