The appearance of several children's games based on creation of algorithmic sequences for controlling characters shows the growing importance given to the development of computational thinking at elementary level.

To do so, these interfaces must be evaluated. Researches show promising results when using neurophysiologic measures of users to support the evaluation of traditional methodologies. This work presents the study and development of a software capable of recording and cataloging neurophysiologic measures based on electroencephalogram (EEG). To this end, two EEG low cost, Neurosky Mindwave and Emotiv EEG were used as data acquisition devices. The software was developed using the C Sharp programming language and the manager of database Microsoft SQL Server Express. Through the developed software, called INTELLECTUS, research and studies in the field of Neuroscience can be conducted. Based on related work, an experiment was conducted. In this, it was possible to perform the catalog data for two EEGs.","PeriodicalId":423409,"journal":{"name":"Proceedings of the 14th Brazilian Symposium on Human Factors in Computing Systems","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126708773","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}

Over time, we realized that interface solutions based on such types of interaction grew in a rapid and disorderly way, without any concern for the formalization of development stages. In addition, issues related to the way these interactions are represented, the context in which they occur, and the environmental behavior in response to these interactions became relevant. In this sense, this paper brings a contribution to the practical approach of a Where-What-Why-How Model for the development of interactive environments. The proposal focuses on three main points: (i) actions that must be performed by the interactive environment;(ii) the situations that trigger the implementation of the actions by the environment; and (iii) the expected behavior once the situations have been recognized. The illustration of the proposal is made through a complete case study that contemplates all development stages and the physical implementation of a remote control that triggers actions in the real world (TV) and in the virtual world (graphical representation of the remote control), which compose the interactive environment.","PeriodicalId":423409,"journal":{"name":"Proceedings of the 14th Brazilian Symposium on Human Factors in Computing Systems","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129846811","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}

We used the Semiotic Inspection Method (SIM), a Semiotic Engineering evaluation method. The results indicate that the reputation communication model is a good opportunity to support decision-making at human-computer interaction time.

In this paper, we propose a model of interaction via gestures and test its efficiency through the creation of an infrastructure.
