This is even more important for individuals with severe mental health problems, but they have many barriers that make it very difficult for them to be physically active, including lack of motivation. In this paper, we propose an exergame that aims to help these people integrate PA into their daily lives. This exergame is designed on a smartphone in order to be able to follow the level of activity of the player on a daily basis. It offers game mechanics that allow the player to manage their PA. However, it encourages them to be physically active so that they can progress more easily in the game. The application uses an activity detection algorithm to measure the level of PA. We offer a preliminary study on healthy subjects on a demo version of the game that observes their gaming experience. The results show that the mechanics are globally appreciated and that the game allows each player to manage his PA as he wishes.","PeriodicalId":130190,"journal":{"name":"Proceedings of the 11th PErvasive Technologies Related to Assistive Environments Conference","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123885006","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}

The other group consists of patients that had been diagnosed with epistaxis and not been prescribed any of the three anti-thrombotic drugs. We find a strong negative correlation between the incidence of epistaxis and outdoor temperature for the group that had not been prescribed any of the three anti-thrombotic drugs, while there is a weaker correlation between incidence of epistaxis and outdoor temperature for the other group.

This work investigates a novel approach for improving the results of an early gesture classification model. The method involves augmenting the input sequence of human poses of a partially observed gesture with a series of poses predicted by an auxiliary recurrent neural network sequence-to-sequence motion prediction model before being fed into a random forest gesture classifier. By concatenating the partially observed ground truth sequence with the forecasted motion sequence, we are able to significantly improve early gesture recognition accuracy. When forecasting 25 future frames of a partially observed input gesture sequence of 50 frames, recognition accuracy improves from 45% to 87% on average when evaluated on the MSRC-12 gesture dataset.","PeriodicalId":130190,"journal":{"name":"Proceedings of the 11th PErvasive Technologies Related to Assistive Environments Conference","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114853760","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 chose a sociological ethnographic approach with eight households, methodologically mainly focusing on qualitative data gathered through a series of household visits. For data analysis we aim at extending the Domestic Robot Ecology (DRE), which was originally developed based on ethnographic studies with vacuum cleaning robots, and for data interpretation we base our work on a newly proposed sociological framework, we call everyday-life centered approach (ELCA).","PeriodicalId":130190,"journal":{"name":"Proceedings of the 11th PErvasive Technologies Related to Assistive Environments Conference","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116963706","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}

This paper reports on a qualitative study which used interviews and thematic analysis to study the experiences of one company with an innovative system designed to support workers assembling small lot sizes. The system provides photographs and instructions to people doing manual assembly of engines. The study was done after an extended pilot, and before the next release that will be rolled out to the main assembly lines. The goal of the study was to understand the needs and problems in practice in order to support people developing the next generation of these types of systems. The results highlight the importance of integrating these systems with existing systems, but also the way in which the way the information is delivered depends on the primary goal, e.g. supporting different variants, new workers or quality.","PeriodicalId":130190,"journal":{"name":"Proceedings of the 11th PErvasive Technologies Related to Assistive Environments Conference","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114584468","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}

Our hypothesis is that the admission (initial) patient assessment, when combined with seasonal information can provide more accurate insights for the patient diagnosis. For instance, when cough is the symptom, the probability for flu could be higher during the winter (flu season). We hereby present a method to estimate the temporal variation of the probability for a diagnosis, when the initial patient assessment is known. In order to develop the model, we utilized a large synthetic medical claims dataset from the Centers for Medicare and Medicaid Services. We used the Apriori algorithm to calculate the support and confidence for each 'admission_diagnosis~final_diagnosis' itemset. For each itemset, 52 rules were generated, one for each week of a calendar year. The Apriori output was filtered so that only itemsets with the 'admission diagnosis' on the Left Hand Side(LHS) are extracted. We furthermore smoothened, using the Exponentially Weighted Moving Average (EWMA) algorithm, and then visualized the week-by-week variability of confidence, for any 'admission_diagnosis~fmal_diagnosis' pair of interest. With our approach, researchers can observe seasonal variations of the diagnosis element, and further study these variations for causal knowledge discovery.","PeriodicalId":130190,"journal":{"name":"Proceedings of the 11th PErvasive Technologies Related to Assistive Environments Conference","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117224306","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}

Motion information of a segmented silhouette, which when extracted can provide a useful cue for classifying different behaviours. Also, the projection histogram and variation in human shape can be used to describe human body postures and subsequently fall events. The proposed approach presented here extracts motion information, using best-fit approximated ellipse around the human body and in addition projection histogram features to further improve the accuracy of fall detection.
