We introduce a new usability inspection method called HED (heuristic evaluation during demonstrations) for measuring and comparing usability of competing complex IT systems in public procurement. The method presented enhances traditional heuristic evaluation to include the use context, comprehensive view of the system, and reveals missing functionality by using user scenarios and demonstrations. HED also quantifies the results in a comparable way. We present findings from a real-life validation of the method in a large-scale procurement project of a healthcare and social welfare information system. We analyze and compare the performance of HED to other usability evaluation methods used in procurement. Based on the analysis HED can be used to evaluate the level of usability of an IT system during procurement correctly, comprehensively and efficiently.
Social Networking Services (SNS) have gained immense popularity in developing countries like India,where digital natives are actively communicating on these platforms. Understanding the interactionbetween technology systems and digital natives, and proposing guidelines and recommendations for thedevelopment of better systems is highly valuable. Prior research examining users’ motivations and actualusage of photo tagging systems is limited, and predominately focused on Flickr and adult users. In order tounderstand in detail why, how, and with whom users tag digital photos on Facebook, a qualitative essaybasedexploratory study is organized with 67 digital natives in India. The study aims to build understandingof the various gratifications, motivations, experiences, and practices associated with Facebook phototagging, focusing on technologically savvy Indian digital natives. Our results reveal that photo taggingpractices by digital natives vary substantially, especially among gender groups. Facebook photo tagging ispopular among Indian boys, and they are more willing to embrace and use it. Meanwhile, involvement ofIndian girls is considerably limited, as they tend to avoid Facebook photo tagging, mainly due to privacyconcerns, as well as social norms and pressures.
Despite the rapid adoption of Facebook as a means of photo sharing, minimal research has been conducted to understand user gratification behind this activity. In order to address this gap, the current study examines users’ gratifications in sharing photos on Facebook by applying Uses and Gratification (U&G) theory. An online survey completed by 368 respondents identified six different gratifications, namely, affection, attention seeking, disclosure, habit, information sharing, and social influence, behind sharing digital photos on Facebook. Some of the study’s prominent findings were: age was in positive correlation with disclosure and social influence gratifications; gender differences were identified among habit and disclosure gratifications; number of photos shared was negatively correlated with habit and information sharing gratifications. The study’s implications can be utilized to refine existing and develop new features and services bridging digital photos and social networking services.
