Practicing sports in the outdoors as a way to reduce stress levels, improve health and even as an incentive to enhance social relations, has encouraged more and more people to leave the sedentary lifestyle to perform activities like walking, jogging, hiking, biking, among others. This trend of practicing outdoor sport activities also was driven by new technological gadgets (e.g., smartphone whit special...
The reduction in physical and social activity in elderly people degrades the aging process, causing or increasing suffering to the individual and to his family and friends. Most times, the individual well-being is related to the strength of the social bonds with the family and friends group, so it is important to keep this bonds in the various stages of life, especially in the later life, when the...
Progression of Parkinson disease (PD) increases severe motor symptoms such as bradykinesia, tremor, gait disturbance and postural instability, interfering with patients' daily life autonomy. Clinical evaluation is based on specific Scales like Hoehn & Yahr (H&Y) or UPDRS scales. The main goal of the study was to identify motor changes in the kinematic parameters related to different stages...
The existing Massive Open Online Courses (MOOCs) about Frailty, Falls, and Functional Loss Education (3Fights@Edu) are scarce in Europe and the information packages are mainly focused on specific disease/health topics (for instance, chronic illness, disability, obesity or nutrition). In this paper, the overall structure and organization of a MOOC-related with geriatric syndromes is presented, in order...
Quite often linear variables are not sensitive enough to explain the changes in the motor behavior of elite athletes. So, non-linear variables should be selected. The aim was to compare the fractal dimension before and after a maximal bout swimming front-crawl. Twenty-four subjects performed an all-out 100m trial swimming front-crawl. Immediately before (Pre-test) and after the trial (Post-test) a...
Games have been used extensibvely for physical training. In this study emphasis is placed on computerized physical exercise and its positive effects in the physical and mental capacity as well as the quality of life of participants. Improvements are considered in two cases of different physical exercise protocols: balance and aerobic protocol. Twenty two elderly women participated in the pilots (age...
Augmented reality allows users to enhance their perception of the real world by using technology to overlap digital information onto their field of view. This raises challenges of a technical and conceptual nature, the latter particularly from an interaction design standpoint. The implementation of such technology has advantages in many areas of human activity, including its use in clinical interventions...
This work presents a dataset of functional fitness tests acquired with Kinect v2 and physiological sensors. The dataset contains both young and senior subjects executing a number of fitness tests meeting scientific standards of reliability and validity. The main objective is the ability to assess lower body strength, endurance, gait speed, agility and balance from the data obtained from commercially...
Wheelchair racing, an important event in Paralympics, it requires huge effort from its athletes to overcome the resistive forces. The resistive forces in wheelchair racing are aerodynamic drag and rolling friction. CFD methodology can play a determinant role in aerodynamic analysis. The aim of this study was to analyses the aerodynamic drag at different speeds and attack angles of a human head with...
In the last century medical progress has substantially reduced the morbidity and mortality in somatic diseases. However there is a "new morbidity" with an increase of psychomotor developmental, learning, behavioral and mental disorders often with an initial onset in about 20% of childhood. A social gradient in terms of health inequalities is known. Reducing this new morbidity of child and...
Visually impaired people find navigating within unfamiliar environments challenging. Many smart systems have been proposed to help blind people in these difficult, often dangerous, situations. However, some of them are uncomfortable, difficult to obtain or simply too expensive. In this paper, a low-cost wearable system for visually impaired people was implemented which allows them to detect and locate...
The world population is aging, all countries are experiencing an increase of elder population. The pace of aging population in many developing countries is substantially faster than in the past. Consequently, these countries must adapt much more rapidly to this aging. Therapy and Physical activity helps to improve health and well-being in the elders, for it brings longevity and improves quality of...
Computer vision is steadily gaining importance in many research fields, as its applications expand from traditional fields situation analysis and scene understanding in video surveillance to other scenarios. The sportive context can represent a perfect test-bed for many machine vision algorithms because of the large availability of visual data brought by wide spread cameras on a relatively high number...
The aim of this paper is to identify a set of heuristics for designing assistive ‘gamer-friendly’ environments. These heuristics are based on the literature review on game heuristics, game interfaces addressed to older adults and assistive technologies. Forty-seven papers published between 1980 and 2016 in English and Portuguese-language publications met inclusion criteria. Four web-based games and...
This paper presents the results of a heuristic evaluation of Candy Crush Saga, considering Usability, Playability, Accessibility and Sociability categories and with a special focus on the game adaptation to different generations and to intergenerational interactions and communication. The heuristic inspection was performed by 16 evaluators and was based in a model with 4 inspection categories and...
