Recycling and disposing e-textiles has been a concern in this community for years[20]; however, the impact of designing sustainable wearables is still new territory that requires more exploration. This paper approaches sustainability in the prototyping process by producing wearables that make use of biodegradable material for embedding electronics. We have used mycelium, that unlike other biodegradable materials such as kombucha, algae, or bioplastics, has heat resistance, thermal resistance and hydrophobic properties which makes it suitable to apply in wearables. Moreover, this paper proposes a sustainable life cycle that uses biodegradable materials to embed electronics. For example, we embedded an electronic circuit into mycelium skin to make an accessory. After the accessory has been worn, the electronic components can be reused and the mycelium skin composted. Lastly, we present our method for growing mycelium, our design process using common techniques in embedding electronics, and Myco-accessories as applications to envision the possibilities of this material. This paper aims to contribute to prototyping wearables sustainably by intertwining biomaterials and electronics.","PeriodicalId":112916,"journal":{"name":"Proceedings of the 2019 ACM International Symposium on Wearable Computers","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116685444","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 link between affective states and biophysical data, collected in lab settings, has been established successfully. However, the number of realistic studies targeting affect detection in the wild is still limited. In this paper we present an exploratory field study, using physiological data of 11 healthy subjects. We aim to classify arousal, State-Trait Anxiety Inventory (STAI), stress, and valence self-reports, utilizing feature-based and convolutional neural network (CNN) methods. In addition, we extend the CNNs to multi-task CNNs, classifying all labels of interest simultaneously. Comparing the F1 score averaged over the different tasks and classifiers the CNNs reach an 1.8% higher score than the classical methods. However, the F1 scores barely exceed 45%. In the light of these results, we discuss pitfalls and challenges for physiology-based affective computing in the wild.","PeriodicalId":112916,"journal":{"name":"Proceedings of the 2019 ACM International Symposium on Wearable Computers","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126205827","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}

Emerging batteryless sensor technologies such as sensor enabled RFID (Radio Frequency Identification) create new opportunities for building unobtrusive wearables for older people. This study aims to: i) uncover user perceptions and acceptability of a batteryless wearable sensor concept for hospitalized older people; and ii) present the construction of a new textile integrated wearable sensor incorporating user feedback. We recruited 40 older people (age: 81.0 ± 7.0 years) to wear our initial sensor prototype and used two modified versions of validated questionnaires to evaluate user perceptions and acceptability. Our results showed: i) allowing older people to experience the system created the opportunity for them to develop confidence and trust in the sensing technology, even when they were initially anxious and skeptical: and ii) the first design prototype should ideally be modified to reduce its visibility. To this end, we built a new wearable sensor design.","PeriodicalId":112916,"journal":{"name":"Proceedings of the 2019 ACM International Symposium on Wearable Computers","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123909592","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 demonstrate our model on assessment of recoveries from hemiparetic stroke. A clinically-assessed functional recovery score from hemiparetic stroke is periodically collected alongside daily-living wrist-based accelerometer data. After accelerometer preprocessing steps, inferences on individual sliding windows are performed, followed by an overall assessment over a period of time (e.g., past three days). Using isotonic regression, excluding less relevant datapoints, and model averaging over hyperparameters further improve predictions. Through time series decomposition methods of the sliding window inferences, we visualise informative aspects of recovery patterns: overall recovery trend, diurnal exertion patterns and times of outliers in capabilities exhibited.","PeriodicalId":112916,"journal":{"name":"Proceedings of the 2019 ACM International Symposium on Wearable Computers","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116313191","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}

Recently, end-to-end, deep learning methods, that do not discriminate between representation learning and classifier optimization, have become very popular also for HAR using wearables, promising \"out-of-the-box\" modeling with superior recognition capabilities. In this paper, we revisit and analyze specifically the role feature representations play in HAR using wearables. In a systematic exploration we evaluate eight different feature extraction methods, including conventional heuristics and recent representation learning methods, and assess their capabilities for effective activity recognition on five benchmarks. Optimized feature learning integrated into the conventional ARC leads to comparable if not better recognition results as if using end-to-end learning methods, while at the same time offering practitioners more flexibility to optimize their systems towards specifics of wearables and their constraints and limitations.","PeriodicalId":112916,"journal":{"name":"Proceedings of the 2019 ACM International Symposium on Wearable Computers","volume":"46 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126137535","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}

There has been substantial progress in measuring the level of awareness, however is it not known of any instrument or precise method for the possibility to measure the contents of awareness directly (Seth et al. 2008).

However, obtaining such data annotations is often very challenging in the predominantly mobile scenarios of Human Activity Recognition. As a result, labels often carry a degree of uncertainty-label jitter-with regards to: i) correct temporal alignments of activity boundaries; and ii) correctness of the actual label provided by the human annotator. In this work, we present a scheme that explicitly incorporates label jitter into the model training process.

However, this induces problems due to their differences from conventional displays such as smartphone and e-books. In this research, we focused on the problem of vertical shock caused by walking. This problem interferes with seeing information on HMDs. In this paper, we discuss selection of font shapes to minimize the effect of this problem. If we can clarify the characteristics of the readability of fonts in wearable computing environments, the application designers can select fonts that strike a balance between intended design elements and readability. In this paper, we first investigated the characteristics of fonts used in Japan considering the HMD swing that results from walking, from the viewpoints of readability (text readability) and legibility (ease of letter recognition) using six different fonts. From this evaluation, we find that fonts with very thin horizontal lines and with very thin horizontal and vertical lines should not be presented on HMDs.","PeriodicalId":112916,"journal":{"name":"Proceedings of the 2019 ACM International Symposium on Wearable Computers","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132779593","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}
