Experiences and challenges in designing non-traditional interfaces to enhance the everyday life of children with intellectual disabilities
(2014)
Jadán Guerrero, Janio
;
Guerrero L.A.
Some experiences regarding children with disabilities carried out in Ecuador, Costa Rica and Spain have contributed to realize the importance of reading in order to enhance their daily life activities, independence and social integration. This article describes a qualitative study to understand general issues related to the design of non-traditional technologies for children with intellectual disabilities. A methodological approach is described and explained through the results of exploratory surveys and interviews. According to the information obtained from experts and the method of literacy acquisition proposed by Troncoso and Del Cerro, the design of a smart kit using non-traditional user interfaces is presented. A preliminary evaluation of the first prototype is described. The paper concludes by reflecting upon the importance of literacy acquisition and the challenges to design non-traditional interfaces to support learning of children with intellectual disabilities. The development of the phase two of the prototype and empirical evaluation is part of the future work. © 2014 Springer International Publishing.

Despite the recent progresses in robotics, autonomous robots still have too many limitations to reliably help people with disabilities. On the other hand, animals, and especially dogs, have already demonstrated great skills in assisting people in many daily situations. However, dogs also have their own set of limitations. For example, they need to rest periodically, to be healthy (physically and psychologically), and it is difficult to control them remotely. This project aims to “augment” the service dog, by developing a system that compensates some of the dog weaknesses through a robotic device mounted on the dog harness. The present article shows that the dog’s activity and some indexes of the animal emotional state can be successfully identified by the wearable device. © Springer International Publishing Switzerland 2015.

Modeling and control of a wheelchair considering center of mass lateral displacements
(2015)

This work presents the kinematic and dynamic modeling of a humanwheelchair system where it is considered that its mass center is not located at the wheels’ axis center of the wheelchair. Furthermore, it is presents a new motion controller for human-wheelchair system that is capable of performing positioning and path-following tasks. The proposed controller has the advantage of simultaneously performing the approximation of the robot to the proposed path by the shortest route and limiting its velocity. This controller design is based on two cascaded subsystems: a kinematic controller with command saturation, and a dynamic controller that compensates the dynamics of the robot. © Springer International Publishing Switzerland 2015.

Using machine learning and image processing for character recognition: An application for teaching handwriting
(2015)
Sybenga S.
;
Rybarczyk Y.
The ultimate advances in information technologies lead to new possibilities in terms of educational approaches. One of them, which are the focus of this paper, is to improve the handwriting skills of children by use of a tablet. The Android based application presented here promotes an autonomous learning without losing the input, expertise and preferences of the teacher(s). The app is based on the use of machine learning classifiers and image processing techniques to compare the written character with the character created or uploaded by the teacher and to grade the performance accordingly.

Kiteracy is an educational kit designed to improve the literacy process of children with Down syndrome by enabling higher levels of interaction. The kit is based on two Spanish literacy methods: global and phonics. In this work, we present a qualitative study based on video-recorded sessions with twelve children from a Down syndrome institution. The study analyzes three forms of interactions: cardboard, multi-touch and tangible. The task carried out by special education teachers and children in the experimental sessions involved working in pairs (Teacherchild) and autonomous self-learning (child only). Through the sessions, we identified situations in which the teacher took the control in the cardboard version. In the multi-touch version, both the teacher and the child shared the control. However in the tangible version the child took the control. In the self-learning sessions, we observed that multi-touch and tangible interaction seems to offer an enjoyable time for children. Surveys and interviews with teachers revealed that tangible objects offered greater adaptability to create playful reading strategies. © 2015 ACM.

3D markerless motion capture: A low cost approach
(2016)
Rybarczyk Y.
A markerless motion capture technique is described for reconstructing three-dimensional biological motion. In the first stage of the process, an action is recorded with 2 CCD webcams. Then, the video is divided in frames. For each frame, the 2D coordinates of key locations (body joints) are extracted by the combination of manual identification (mouse pointing) and image processing (blobs matching). Finally, an algorithm computes the X-Y coordinates from each camera view to generate a file containing the 3D coordinates of every visible point in the display. This technique has many advantages over other methods. It does not require too specialized equipment. The computer programming uses open source software. The technology is based on an inexpensive portable device. Moreover, it can be used for different environments (indoor/outdoor) and living beings (human/animal). This system has already been tested in a wide range of applications, such as avatars modeling and psychophysical studies. © Springer International Publishing Switzerland 2016.

Children with disabilities are one of the most vulnerable groups of the population. They experience social exclusion and inequity, as do their difficulties to integrate into society. Many families raising children with disabilities try to do everything to improve their quality of life. This paper describes a case study of an Ecuadorian family who was encouraged to integrate Information and Communication Technologies (ICT) in the everyday life of their girl with intellectual and language disabilities. The experience with the most popular technologies at home-Computer, tablet, smartphone, and videogame console-motivated the whole family to adapt and design assistive technologies for their daughter. Their motivation allowed us to find people and institutions who supported the design of ICT for different disabilities: AINIDIU, HELPMI, CANDI, LUCKI, MAGIC GLASS, JADAN VERBAL, TIC@ULA and KITERACY. An interdisciplinary group of experts participated in the development of these technologies: A Computer Engineer, a Phycologist, a blind person, students and Especial Education teachers. Since 2009, about 50 children with disabilities and 20 Especial Education teachers have been involved in the evaluation of the prototypes. With the support of Universidad Indoamérica and Ecuadorian Government, 1500 children with visual impairment were benefited with the software AINIDIU in some provinces of Ecuador. The article describes the history of this great experience. © Springer International Publishing AG 2016.

Urban stream renovation: Incorporating societal objectives to achieve ecological improvements
(2016)

Pervasive human impacts on urban streams make restoration to predisturbance conditions unlikely. The effectiveness of ecologically focused restoration approaches typically is limited in urban settings because of the use of a reference-condition approach, mismatches between the temporal and spatial scales of impacts and restoration activities, and lack of an integrative approach that incorporates ecological and societal objectives. Developers of new frameworks are recognizing the opportunities for and benefits from incorporating societal outcomes into urban stream restoration projects. Social, economic, cultural, or other benefits to local communities are often opportunistic or arise indirectly from actions intended to achieve ecological outcomes. We propose urban stream renovation as a flexible stream improvement framework in which short-term ecological and societal outcomes are leveraged to achieve long-term ecological objectives. The framework is designed to provide additional opportunities for beneficial outcomes that are often unattainable from ecologically focused restoration approaches. Urban stream renovation uses an iterative process whereby short-term ecological and societal outcomes generate public support for future actions, which may provide opportunities to address catchment-level causes of impairment that often exist across broad temporal scales. Adaptive management, education, and outreach are needed to maintain long-term public engagement. Thus, future work should focus on understanDing how ecological and societal contexts interact, how to assess societal outcomes to maintain stewardship, developing new methods for effective education and outreach, and multidisciplinary collaborations. We discuss potential abuses and the importance of linking societal outcomes to long-term ecological objectives. © 2016 by The Society for Freshwater Science.
