From Extensity to Protensity in CAS: Adding Sounds to Icons
2009
Being aware of the gap between technological offers and user expectations, the paper aims to illustrate the necessity of anthropocentric designs ("user-pulled") and to reveal the dangers of current ICT designs ("technology-pushed"). Since the gap is deepened because of insufficient innovative use of new agent-oriented technology potential, an affordable manner to "invent new Computer-Aided x" application domains is proposed. To substantiate the approach, the domain must be challenging, easy to implement and "as humanist as possible": Computer-Aided Semiosis (CAS). On this background, the paper also presents a new and challenging concept in IT applied research, borrowed from psychology and m…
Adding Knowledge Extracted by Association Rules into Similarity Queries
2010
International audience; In this paper, we propose new techniques to improve the quality of similarity queries over image databases performing association rule mining over textual descriptions and automatically extracted features of the image content. Based on the knowledge mined, each query posed is rewritten in order to better meet the user expectations. We propose an extension of SQL aimed at exploring mining processes over complex data, generating association rules that extract semantic information from the textual description superimposed to the extracted features, thereafter using them to rewrite the queries. As a result, the system obtains results closer to the user expectation than i…
User expectations, use experiences and continued adoption of a mobile secure communication application
2018
The importance of secure communication between employees in enterprises and governmental organizations as well as technologies to support that has increased tremendously over the past years. This study examines the user expectations before and the use experiences during the implementation phase of a mobile secure communication application together with expectation–confirmation and its influence on continued adoption. The study is explorative in nature and empirically based on thematic analysis of qualitative data collected from pilot users of a mobile secure communication application who work in a governmental organization in Finland. The theoretical basis of the study draws from two well-e…
