Different CCT provided by different lighting are important in affecting human beings psychologically and physiologically, as well as visual and non-visual processes. This study aim in finding out the effects of warm white (WW) light (CCT=2700K), cool white (CW) light (CCT=4000K) and artificial Daylight (CCT=6200K) on worker's alertness, visual comfort level, preferences and task performance. A repeated measure experimental study was conducted among 46 office workers under controlled environment. Alertness levels were measured by Karolinska Sleepiness Scale. Office Lighting Survey was used to evaluate visual comfort and preference. Typing speed and accuracy also were tested. Paired Sample T-Test was used and the results showed that there was significant reduction of subjective alertness level in WW light (p=0.001). In term of typing performances, subjects performed significantly better in term of typing speed under CW light and Daylight than WW light. Less typing errors were made under DL, followed by CW light. Meanwhile WW light lead to high typing errors. Besides, CW light is the most preferred whereas subjects feel most comfortable under Daylight. Subjects indicated that they can perform longer works in this coloured-lit environment. The CW light and DL light were more beneficial for office setting for computer-based task.

The manner in which choice is framed influences individuals' decision-making. This research examines the impact of different decision constructs on decision-making by focusing on the more problematic decision constructs: the un-selected and pre-selected optout. The study employs eye-tracking with cued retrospective think-aloud (RTA) to combine quantitative and qualitative data. Eye-tracking will determine how long a user focuses on a decision construct before taking action. Cued RTA where the user will be shown a playback of their interaction will be used to explore their attitudes towards a decision construct and identify problematic designs. This pilot begins the second of a three phase study, which ultimately aims to develop a research model containing the theoretical constructs along with hypothesized causal associations between the constructs to reveal the impact of measures such as decision construct type, default value type and question framing have on the perceived value of the website and loyalty intentions.

“…User testing methods usually involve users being observed while performing pre-defined tasks with the purpose of identifying usability problems (Brinck, Gergle, & Wood, 2001). However, the heuristic evaluation method is the most common usability inspection method for evaluating e-commerce websites (Goh et al, 2013).This method involves a number of evaluators who assess the user interface and judge whether it conforms to a set of usability principles (namely 'heuristics') (Nielsen & Molich, 1990). Finally, Google Analytics involves adding lines of script (e.g., JavaScript) to the pages of a website to gather statistics from them to understand visitors' experiences and therefore predict potential usability problems on an e-commerce website.…”

“…Research has suggested advantages that can be gained if the usability of e-commerce websites is considered or improved. These include increasing the percentage of visitors who purchased from a site and who could then turn into frequent and loyal customers; increasing traffic; increasing sales; and increasing customers' trust, users' satisfaction and purchase intention (Goh et al, 2013;Lohse & Spiller, 1998;Muhtaseb et al, 2012;Nielsen & Norman, 2000;Rianto, Nugroho, & Santosa, 2015;Tedeschi, 1999).…”

This research aims to suggest key design characteristics that are necessary for developing usable e-commerce websites in the Arab world. A comprehensive usability evaluation of four leading Arab e-commerce websites was conducted using the heuristic evaluation method. The results identified major and minor usability problems and major and minor good design characteristics on the selected websites. Based on the results, 51 key design characteristics were suggested. The recommended key design characteristics comprised two levels according to their priority: level one which includes mandatory key design characteristics and level two which includes supplementary design characteristics. The key design characteristics in each level were categorized under specific pages and areas that can be found on any e-commerce website. Such categorizations could direct website evaluators and designers to important pages and areas that should be considered to improve the overall usability of e-commerce websites. The results of this research are particularly important to developing countries which are still facing challenges that may affect the design and accessibility of usable and useful websites. These relate to low speed of accessing the Internet and a lack of website designers who have experience in customers' needs and websites' usable design characteristics.
