Ignoring any reduction in efficacy of remote therapy, it is assumed that therapists’ experiences of communication and their ability to construct a diagnosis on the basis of what they perceive will be influenced by Computer-Mediated Psychotherapy. Participants of the study scaled four emotional factors i.e., intensity, valence, potency and activation to measure the constructive nature of emotional discourse. Among other findings, the study showed that estimating emotional factors of communication did not differ significantly across main delivery modalities (i.e., text, audio and video). The results demonstrate further that telecommunication technologies did not alter the diagnostic level of psychotherapists. However, the reduction of emotional perception is very much remarkable for clinicians’ decisions when discourse is communicated via non-human computer-mediated mode.","PeriodicalId":90597,"journal":{"name":"Journal of interaction science","volume":"5 1","pages":"34-43"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44647324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For research, HCI tries to identify the principles; for specific case studies, HCI tries to improve the user experience or the product delivered. In all approaches, the user task is central, yet the user task may be an artifact of previous implementations (it may suffer implementation bias), and users — and user studies — may therefore accidentally focus on problems with their current task as implemented rather than opportunities for a new HCI approach. In this paper, we use presentations (i.e., giving talks or lectures) as a detailed stand-alone case study, and we show that implementation bias is a serious impediment to thinking clearly about improving the task of delivering quality presentations. We then argue, using a very different example (healthcare IT) that implementation bias is, in fact, a common and serious problem across HCI generally.","PeriodicalId":90597,"journal":{"name":"Journal of interaction science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42149998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Every speaker wants their audience to remember something, even if only that they have been entertained; better, they want their audience — or at least some of them — to go on to do and achieve new things, to act and take forward their inspiration from the talk. Put bluntly, if a talk does not have an effect, what was the point? To achieve an effective outcome, the route from where the audience starts from to where the speaker wants to lead them needs planning and mapping out. Pirate Talks help systematically work out the route. The last R of AARRR is less often emphasised: Pirate Talks aim to get better. A key insight is that what the audience needs to be able to do to learn from a talk is closely aligned to what a speaker needs to do to continually improve the quality of their own talks. Many poor talks happen because the speaker has not tried to improve over a period of giving previous talks — their talks have become routine and dull, with the speaker perhaps confusing comfortable habit for effectiveness. Pirate Talks are a memorable way to be effective, to not only set higher standards but also to help speakers aim at excellence, to aim at continual improvement. The simple mnemonic AARRR also helps chairs and other audience members to facilitate speakers to do better.","PeriodicalId":90597,"journal":{"name":"Journal of interaction science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42419184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In such a popular and competitive market, it is imperative that websites are both practical and pleasant to navigate. Using an eye-tracker, we obtained objective measurements of complexity with subjective ratings of complexity and aesthetics, to explore judgments arising from the perception of university homepages. As expected, high levels of perceived complexity resulted in low aesthetic ratings. Interestingly, fixation count correlated negatively with complexity and positively with aesthetics; a novel finding. We argue that high complexity and negative aesthetic appraisals are a result of cognitive overload due to the limited capacity of working memory. We suggest ways in which web designers can avoid information overload, by complying with the known limits of human cognition, to maximize the positive interaction between webpage and user.","PeriodicalId":90597,"journal":{"name":"Journal of interaction science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44702300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

More recently, globalization and modern communication technologies have contributed to the prevalence of multicultural teams and fast communication paths, creating additional challenges for effective communication. To support multicultural communication, a web-based communication model for multicultural teams (comMCT) was previously developed. To the best of the authors’ knowledge, this is the only communication model for MCTs that provides a web-based representation and includes modules addressing a wide spectrum of interpersonal, structural, functional, and organizational aspects of effective multicultural team communication. The objective of the current effort is to evaluate and enhance the model with the participation of subject matter expert end-users. In the study, an international sample of 15 project managers evaluated the comMCT model on 7 criteria: completeness, structure, language, redundancy, understandability, originality, and usefulness. On a scale of YES!; Rather yes; Partly yes, partly no; Rather no, and NO!, the model was rated as good (corresponding to answer option ‘Rather yes’) or very good (corresponding to ‘YES!’) on all criteria except for redundancy. In addition, participants’ free text comments provided suggestions for improving the model in terms of complexity, interactivity, and calibration. Overall, the comMCT model was considered helpful and useful for supporting intercultural, work-related communication. Yet, further research and incremental optimization are needed in this domain.","PeriodicalId":90597,"journal":{"name":"Journal of interaction science","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48182806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
