The objectives of the test were a) to validate a set of heuristic indicators for the evaluation of the accessibility of statistical charts presented in a previous work [7]; b) to identify new barriers and preferences for users with low vision in the access and use of this content not previously contemplated. 12 users were tested, with a variety of conditions associated with low vision: low visual acuity (6 users), reduced central vision (2 users), reduced peripheral vision (2 users), blurry vision (1 user), sensitivity to light (3 users), Nystagmus (2 users) and color vision deficiency (CVD) (4 users). From a quantitative standpoint, accessible versions of charts were more efficient, effective, and satisfactory. From a qualitative point of view, results verify the relevance of heuristics H2, Legend; H3, Axes; H6, Data source (as data table); H10, Safe colors; H11, Contrast; H12, Legibility; H13, Image quality; H14, Resize; H16, Focus visible; H17, Independent navigation; related to the proposed tasks. As new observations, tooltips were highly valued by all users, but their implementation must be improved to avoid covering up significant parts of the charts when displayed. The data table has also been frequently used by all users, especially in the non-accessible versions, allowing them to carry out tasks more efficiently. The position and size of the legend can be a significant barrier if it is too small or appears in an unusual position. Finally, despite the limitations related to color perception, users prefer color graphics to black and white, so, to target all profiles, it is necessary to redundantly encode categories with colors and patterns as well.","PeriodicalId":405515,"journal":{"name":"Proceedings of the XXII International Conference on Human Computer Interaction","volume":"123 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131190525","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}

To assist them in this task, 3D avatars can be used to guide them through the different exercises. In this paper, we have transformed and improved a movement-based physical rehabilitation system, called Rehabilita, to enhance the user experience of the patients. By adding a 3D avatar to guide users through physical therapy, and updating the UI elements of the system, we have improved the user experience of the patients. These modifications have followed the proposals of a heuristic evaluation proposed in a previous work. An evaluation with real users was later carried out to measure the effectiveness and efficiency of the modifications performed over the original system. The assessment results show that users can follow the steps of an exercise more easily, although some limitations must be discussed.","PeriodicalId":405515,"journal":{"name":"Proceedings of the XXII International Conference on Human Computer Interaction","volume":"82 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129949172","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 work focuses on presenting an application designed to delay and minimize the effects of cognitive decline, stimulating skills such as memory (short term, more specifically, from work) and logical reasoning. To this end, four implemented features are presented, which are detailed in this work: Games & Logic, Stay Informed, Reminders/Mural and Chatbot Remi.","PeriodicalId":405515,"journal":{"name":"Proceedings of the XXII International Conference on Human Computer Interaction","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128143006","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 environments where the user is an elderly person, the recognition of patterns becomes useful to analyze the possible responses of the user to certain scenarios where it is necessary to make use of the supporting technology. The participation of the users is necessary to learn from their daily habits. With the rise of ambient intelligence and assistive solutions collect information from both the user and the environment in real time to adapt and be able to learn from it. In this context, the current work proposes to learn activity patterns through training by using agent-based simulations. The objective of the training is to train avatars in 3D scenarios, which recreate those physical activities that the real user cannot perform due to their physical condition. The validation of the proposed approach was in a virtual living laboratory by using 3D simulations as assisted environment scenarios.","PeriodicalId":405515,"journal":{"name":"Proceedings of the XXII International Conference on Human Computer Interaction","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122248524","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 world is looking into alternate ways to train dentists. This paper aims to address these challenges by proposing a virtual reality-based training application that helps dentists gain initial training in the risk-free virtual scenario. The application was evaluated by 26 dental trainees, who carried out different tasks on dental treatments in the virtual scenario. After testing, each participant completed the System Usability Scale (SUS) questionnaire. The SUS data analysis resulted in a score of 82.50, which indicates that the participants like the virtual reality application and would recommend it to their colleagues. The demographics analysis showed female SUS score greater than males, and participants aged <=30 years had SUS scores more than those aged >30 years. However, there is a need for more testing sessions to generalise the results of this research.","PeriodicalId":405515,"journal":{"name":"Proceedings of the XXII International Conference on Human Computer Interaction","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116153362","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 interactive pet can recognise the user’s emotional status using computer vision, and respond to it with a low-level empathy system based on mirroring behaviour. For example, if you approach it with a happy face, the pet will greet you and move in a nimble way. A repulsive magnetic levitator is attached to a mechanical stage controlled by a computer system. On top of it, there is the pet playground, where a house, a ping-pong ball,a xylophone and other accessories are placed. Two cameras allow to capture the user’s face and the objects placed on the playground, so that the pet can interact with them. LevPet is an exploration of how to communicate internal state with only a levitating sphere; it is a platform for experimentation and an interactive demo that brings together an outer-worldly levitating metallic sphere with familiar things like emotions and a playground made of traditional items.","PeriodicalId":405515,"journal":{"name":"Proceedings of the XXII International Conference on Human Computer Interaction","volume":"303 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115830068","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}

However, these tools are not currently accessible to people with disabilities who face barriers preventing them from fully using them. To make these tools accessible, standards must be met. But, designers and developers don’t apply these standards because it is a complex task. As a solution, an accessibility requirements analysis is introduced in this paper, providing a list of requirements, along with design patterns resources, that establish a guide for developing a web video conferencing tool with an interface that people with disability could use.

The increasing visibility of these has given way to several investigations on the acceptance and perception of this technology, however, in many of these studies the participants are based solely on a preconceived belief since most have not driven or had contact with these types of vehicles. This issue needs to be explored further, however, test studies with real AVs are expensive, dangerous and unethical. In response to this, virtual reality emerges as a possible solution as it provides a realistic, safe and controlled environment, where different road and weather situations can be implemented. This paper presents a preliminary research design, based on the Technology Acceptance Model (TAM), which seeks to assess and infer the level of acceptance of AVs and user behaviour when using and interacting with them, based on an immersive virtual simulation of an AV, where the user is exposed to a risky situation where the vehicle is unable to recognize the lane due to weather difficulties.","PeriodicalId":405515,"journal":{"name":"Proceedings of the XXII International Conference on Human Computer Interaction","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121332163","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}
