The project aims at supporting accessibility for People With Disability (PWD) and elderly in various situations of their everyday life. Offering context awareness, user profiles and trails management, the model is a base for applying assistive technologies that fulfills accessibility needs. Moreover, in the proposed model, we devised an ontology. Besides the benefits of intrinsic semantic representation, the use of an ontology fosters future integration with others solutions. We also present a case study based on a prototype, which was developed to evaluate the model. This assessment used a smart wheelchair, operated by a paraplegic person, which is under development at University of the Sinos Valley (Unisinos).","PeriodicalId":91811,"journal":{"name":"The ...

Physical mobility is a fundamental component of overall mobility. This paper presents our \"technology tea party\" methodology. We have used this method to explore older adults' reaction to utilizing different technologies to maintain their mobility, in particular, games consoles to promote exercise at home. At our tea party, participants experienced problems with initially getting started with the console but with minimal support were able to interact with the system and start to explore the benefits they could gain from using such a system. They saw the benefits not only as exercise but also as promoting social interaction. We are now using this method in the design process for an \"intelligent\" walking aid to improve the ability of older adults to walk around shopping centres. In this paper we advocate the involvement of older adults throughout the design process and we present tea parties as a potential method to use in early stages to elicit requirements.","PeriodicalId":91811,"journal":{"name":"The ...

However, there is a lack of a commonly used, standard dataset and established benchmarking problems. In this work, a new dataset for physical activity monitoring --- recorded from 9 subjects, wearing 3 inertial measurement units and a heart rate monitor, and performing 18 different activities --- is created and made publicly available. Moreover, 4 classification problems are benchmarked on the dataset, using a standard data processing chain and 5 different classifiers. The benchmark shows the difficulty of the classification tasks and exposes some challenges, defined by e.g. a high number of activities and personalization.","PeriodicalId":91811,"journal":{"name":"The ...

In QBH the goal is to find the song(s) most similar to a hummed query in an efficient manner. In this paper, we focus on providing a brief overview of the representations to encode music pieces, and also on the methods that have been proposed for QBH or other similarly defined problems.","PeriodicalId":91811,"journal":{"name":"The ...

In real life there will be situations where the inhabitant receives visits from family members or professional health care givers. In such cases activity recognition is unreliable. In this paper, we investigate the problem of detecting multiple persons in an environment equipped with a sensor network consisting of binary sensors. We conduct a real-life experiment for detection of visits in the office of the supervisor where the office is equipped with a video camera to record the ground truth. We collected data during two months and used two models, a Naive Bayes Classifier and a Hidden Markov Model for a visitor detection. An evaluation of these two models shows that we achieve an accuracy of 83% with the NBC and an accuracy of 92% with a HMM, respectively.","PeriodicalId":91811,"journal":{"name":"The ...

This methodology is adapted to the specificities of the data used: very small number of samples and high number of variables. Such data is generated using underlying dependencies and seasonality assumptions, from Meme phrases volume data. By the use of a resampling technique along with the proposed variable selection scheme, significant results are obtained, and the test Normalized Mean Square Error performances are improved. The results indicate that with the assumptions made on the data structure, variable selection is desirable. Also, the obtained information on the selected variables seem to cluster the time series in two very different classes: a set of approximately 600 series, which yield good NMSE, and seem to require very similar sets of variables for the prediction; and another set of 300--400 series, for which only the previous series value is of interest for the prediction. This first analysis clearly illustrates the future need to perform a more thorough analysis of the selected variables for each of the batch of series.\u0000 Also, taking a close look at the possible dependences between the series inside a batch should give information as to why and how they are similar and have found themselves to be grouped under the same batch.","PeriodicalId":91811,"journal":{"name":"The ...
