By integrating conductive elements into the tangibles' sides, communication between embedded microprocessors is enabled, such that a connected composition can be computed without relying on any marker tracking information. Consequently, the virtual counterparts of the tangibles can be aligned, and this virtual composition can be attached to a single marker as a whole, increasing the tracking robustness towards occlusions and perspective distortions. A technical evaluation shows that this approach provides more robust augmentations if a tangible block in a composition is occluded by at least 50% or perspectively distorted by at least 40 to 50 degrees, depending on the block's size. Additionally, a test with users relying on the use case of a couch configuration tool shows promising results regarding usability and user experience.","PeriodicalId":118996,"journal":{"name":"Extended Abstracts of the 2020 CHI Conference on Human Factors in Computing Systems","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116973862","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 create a lexical circuit-event database based on 152 student reports from the undergraduate physical-computing course in a local art school. The LSTM-CRF network of FrzitBot is trained on that database, and is able to extract the input and the output events from the user's description, and generate the circuit and the code along with the construction guidelines. A user study shows that FritzBot can significantly reduce the construction effort and time spent for novice users on physical-computing task.","PeriodicalId":118996,"journal":{"name":"Extended Abstracts of the 2020 CHI Conference on Human Factors in Computing Systems","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125137974","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}

A variety of statements are made on the mutual information of the signals flowing through the model. For example, data processing can only reduce or retain mutual information, not increase it. It is suggested that instrument designers should consider creating high-fidelity musical instruments that generally avoid discarding information. Noise and many-to-one mappings have a tendency to decrease the mutual information, potentially reducing the fidelity of a digital musical instrument. Also, musicians need to rehearse their performances in order to avoid making noisier gestures. Overall, it is hoped that this paper and other related papers by the authors can show how to quantify information processing in user interfaces for continuous control.","PeriodicalId":118996,"journal":{"name":"Extended Abstracts of the 2020 CHI Conference on Human Factors in Computing Systems","volume":"124 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123250253","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}

Parts of the display are hidden during interaction, which can lead to incorrect input. For simplicity, instead of general text input a small set of answer options are often provided, but these are limited and impersonal. In contrast, free-form drawings can answer messages in a very personal way, but are difficult to produce on small displays. To enable precise drawing input on smartwatches we present a magnetic stylus that is tracked on the back of the hand. In an evaluation of several algorithms we show that 3D position estimation with a 7.5x20mm magnet reaches a worst-case 6% relative position error on the back of the hand. Furthermore, the results of a user study are presented, which show that in the case of drawing applications the presented technique is faster and more precise than direct finger input.","PeriodicalId":118996,"journal":{"name":"Extended Abstracts of the 2020 CHI Conference on Human Factors in Computing Systems","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115049116","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}

By controlling the translational and rotational motion of the weight via four parameters (target position, trajectory, speed, and repetition), the gadget can present weight shifts to the user who holds it. In addition, by using weight shifts together with other robotic behaviors, such as hand gestures, facial expressions, and speech dialogues, it is expected that emotional and/or intentional messaging between users is enhanced. In this hands-on demonstration, visitors will have an opportunity to hold OMOY and feel some weight shift patterns.

Therefore, it is very important for them to maintain their physical prowess by encouraging the performance of physical activity. Previous research has focused primarily on physical activity as a single task without consideration of numerous additional coinciding events that almost always co-occur. The most common concomitant, secondary task (i.e., dual-task) is related to the cognitive requirements associated with daily activity pursuits. Thus, any procedure designed to promote greater physical activity should include complex tasks. In addition, the older population is diverse, and therefore, physical activity should be personalized according to individual capabilities and skills. We intend to combine navigation as a secondary task to walking, as a task \"instructor\", guiding the users through their personalized routes and also provide an added value of doing physical activity outside the home.","PeriodicalId":118996,"journal":{"name":"Extended Abstracts of the 2020 CHI Conference on Human Factors in Computing Systems","volume":"144 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116406738","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}

Across two phases, we varied the association in three between-subjects conditions, i.e., associative inference, repetition, and irrelevant (control). Our study results showed limited impact of association type on participants of low cognitive ability. In contrast, for participants of high cognitive ability, their discrimination of fake news from real news tended to be worse for the associative inference condition than for the other two conditions. Thus, our findings suggest that individuals of high cognitive ability are likely to be susceptible to form the belief of fake news, but differently from those of low cognitive ability.","PeriodicalId":118996,"journal":{"name":"Extended Abstracts of the 2020 CHI Conference on Human Factors in Computing Systems","volume":"158 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116739833","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 particular, women and the LGBTQ+ community are often disproportionately affected by severe forms of threats that could transfer to risks to their physical safety. However, safety tools and platform policies often assume users are more homogeneous which may not acknowledge the varying needs of vulnerable populations affected by social oppression. This problem is exacerbated in small closely-knit communities like the Caribbean where it may be difficult to recover from or avoid abusers. Although legislation for online safety exists, they are enforced in few countries throughout the region, and there are few cases of victims being heard in court. My dissertation work attempts to address this problem by developing a holistic understanding of how to design safety tools that acknowledge cultural differences, legislative constraints, and social oppression for vulnerable groups.","PeriodicalId":118996,"journal":{"name":"Extended Abstracts of the 2020 CHI Conference on Human Factors in Computing Systems","volume":" 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113950505","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}
