Proliferation of industrialized agriculture has created public health concerns due to rise of obesity and diet-related disease around the world. People who are aware of the effects of food choices on human body, have been trying to become food literate. In other words, they have been trying pursuing to obtain necessary knowledge to select, prepare and consume healthy food. Yet, information pollution and lack of education engenders gastro-anxiety which is a term to describe the suspicion about foodways. In this context, an application called Kliktag introduces itself as “A Healthy Food Advisory.” The application seems to alleviate the gastro-anxiety of its users. Due to this impression, this study aims to analyze the competency of this application to empower the level of food literacy among users. It also aims to investigate the user experience of Kliktag through an analysis framework based on parameters such as Onboarding, Search Experience (Findability), Visual Hierarchy, Visibility, Data Visualization, User Collaboration and Editorial Tone. It was also analyzed how user behaviors were changed related to evolving food literacy. To achieve this aim, a multi-method user research based on two separate phases was conducted. The study firstly focused on the momentary first-time user experience through a usability test while the second phase was based on a 10 day-diary study that aims to understand the evolving cumulative user experience on the mobile app. According to the findings, users could tolerate the detrimental effects of user experience issues and maintain a particular level of food literacy in short term.

Customer journey mapping is a continuous process that demands end-to-end innovation through qualitative and quantitative user research. It helps to identify key points where service or communication breakdown is most likely and where they are mostly valued. Buyer journey mapping study of Gittigidiyor (Ebay Turkey) revealed the fact that the frequency of the repeat purchase was significantly limited although a high traffic and average visit time were observed. This finding pointed to the need to improve the pre-purchase experience in the web site towards motivating the users to visit more and inspiring them to buy more items. Relying on solid quantitative and qualitative research, this paper presents the action set taken for the realization of this goal. In this context the main action of the process is to renew the category structure through a focus on compatibility, which subsequently enabled the integration of a set of effective improvements. Firstly, this approach led to the improvement of a new listing creation process for the sellers by implementing an innovative and error-free experience. It also enabled to improve the search usability by presenting more relevant results, which was supported with a new smart auto suggestion feature in the search engine box and with smart compatibility filters in search results. The new compatible structure between vertical and horizontal categories brought the implementation of some persuasive features. It provided the increase in count of payment (COP) per item and average selling price (ASP) through cross-selling and up-selling features. Finally, the pre-purchase experience was supported by the integration of product rating/review mechanisms and targeted e-mailing based on previous purchase history of the customers.

Social media has a significant impact in our daily social lives, which challenges the traditional face-to-face interaction and/or other conventional media. Most of the social media platforms provide unique and effective web sites that enable the users to connect and interact with one another yet they also update their sites with Web 2.0 improvements and innovative ways of interaction. Twitter and Facebook have launched their own applications that became really popular among users. However, there are also third-party applications, which enable the use of diverse social networking sites through one platform. These platforms are within the reach of everyone and can be accessed directly from desktop without any browser needed. This research focuses on the usability of these third-party management applications. In this context, it will explore whether the desktop versions (third-party software) of those platforms enhance the interaction capabilities and improve user experience. In this regard the focus will be on an application that enables the use of multiple social media sites simultaneously through a single graphical user interface, ‘Yoono’. The user interaction with multiple accounts and social media services at the same time presents the ability to show the information in one screen rather than having separate tabs like has been done in typical browser view. Also it might be possible to have an estimate about if the user prefers to have separate tabs or just one tab to show all of the information regarding the social media that he/she is using. In order to understand this, a qualitative usability test, based on multi-method approach, was carried out with a sample of 8 participants who were experienced mobile social network site (SNS) users. Tests were conducted on a desktop computer with Yoono. After a background questionnaire, the participants were observed during the task executions and additional data was collected through eye-tracking. After the session, participants were asked to fill out a post-test form while having a small debriefing interview to gain a detailed insight into their experience. Findings support the notion that the usability problems might shroud the new and innovative capabilities of Yoono and prevents it to become an application that users would chose to use instead of browser interaction and needs further development in order to be an alternative to browsing.
