Hill Climb Game Play with Webcam Using OpenCV

Computer vision is a process by which we can understand how the images and videos are stored and manipulated, also it helps in the process of retrieving data from either images or videos. Computer Vision is part of Artificial Intelligence. Computer-Vision plays a major role in Autonomous cars, Object detections, robotics, object tracking, etc. OpenCV (Open Source Computer Vision Library) is an open source computer vision and machine learning software library. OpenCV was built to provide a common infrastructure for computer vision applications and to accelerate the use of machine perception in the commercial products. It comes with a highly improved deep learning (dnn ) module. This module now supports a number of deep learning frameworks, including Caffe, TensorFlow, and Torch/PyTorch. This does allow us to take our models trained using dedicated deep learning libraries/tools and then efficiently use them directly inside our OpenCV scripts. MediaPipe is a framework mainly used for building audio, video, or any time series data. With the help of the MediaPipe framework, we can build very impressive pipelines for different media processing functions like Multi-hand Tracking, Face Detection, Object Detection and Tracking, etc.

Usability and Accessibility of the ArtontheBrain™ Virtual Recreation Activity for Older Adults With Low Vision Due to Age-Related Macular Degeneration

Experiencing visual art can inspire, be an overall positive leisure activity, and has been linked to improved cognition, especially in older adults. Access to artwork in a museum environment can comprise a variety of barriers, including difficulties linked to its visual experience for persons that are visually impaired. The present study explored the barriers and facilitators experienced by 15 older adults (age 65 to 93) living with age-related macular degeneration when using an iPad to access ArtontheBrain™, a virtual art museum recreation experience created by members of this team. Using the Concurrent Think Aloud method, participants were asked to continuously comment on their experiences with the application while being audio/video recorded. Indeed, codes were determined by identifying frequently stated and emphasized ideas or behaviors of participants using the ArtontheBrain™ application. Transcripts underwent thematic analysis and indicated that the main access barriers were linked to control of the contrast, magnification, and the tactile interface on the tablet device. The learn and play activities as well as the text-to-speech feature were identified as facilitators for ArtontheBrain™ engagement. The present findings should also be considered in the larger context of application development, as this study provides insight pertaining to the needs of low vision individuals regarding usability and accessibility.

Les transformations dynamiques des configurations de participation formatives en situation de travail : le cas des ergothérapeutes

Un tiers du temps de formation des ergothérapeutes se déroule en stage. Cependant il n’existe aucune recommandation didactique pour l’encadrement et le suivi des stagiaires. Cette question émerge : Quelles sont les modalités pratiques de l’accompagnement tutoral dans l’acquisition des compétences en stage ? Nous proposons, ici, d’explorer des enregistrements audio-vidéo de pratiques tutorales en situation de travail réel couplés à des entretiens semi-directifs auprès des tuteurs. Les données sont analysées selon les principes analytiques de l’Analyse Conversationnelle issue de l’ethnométhodologie. En mettant en relation les modalités de participation des acteurs avec les enjeux et implications de la formation professionnelle des ergothérapeutes, nous repérons le caractère dynamique et poreux de quatre configurations de participation typiques de la formation : observation, co-animation, monstration et laisser-faire.

Concealing a Secret Message in a Colour Image Using an Electronic Workbench

Steganography is the art of concealing security data in media, such as pictures, audio, video, text, and protocols. The objective of this paper is hiding a secret message in a colour image to prevent an attacker from accessing the message. This is important because more people use the Internet all the time and network connections are spread around the world. The hidden secret message uses two general algorithms that are embedded and extracted. This paper proposes a new algorithm to conceal a secret message in a colour image in LSB. This algorithm includes three phases: 1) dividing the colour image into a number of blocks, 2) concealing the secret message, and 3) transmitting the stego-image from the sender in a multiplexer network and receiving it through a demultiplexer network using an electronic workbench. The outcome of the new algorithm demonstrates good efficiency, high security, and robustness and is executed quickly. The system is evaluated through the measurements of mean square error, peak signal-to-noise ratio, correlation, histogram, and capacity.

A pandemia do novo coronavírus (COVID-19) tem gerado profundos impactos na sociedade, afetando a saúde física e mental dos indivíduos e as interações familiares. Na realização de pesquisas envolvendo famílias, tecnologias da informação e da comunicação (TICs) vêm sendo implementadas com o intuito de compreender as dinâmicas relacionais durante a pandemia e garantir a continuidade de estudos iniciados anteriormente. O objetivo deste estudo é apresentar possíveis adaptações, para a modalidade on-line, dos procedimentos de coleta de dados em pesquisas envolvendo observação das interações familiares. Trata-se de um artigo metodológico, em que são discutidas as potencialidades da observação on-line, como a maior abrangência geográfica e validade ecológica, mas também os desafios, como a dificuldade de padronizar os procedimentos de coleta de dados, por conta da variabilidade na qualidade dos equipamentos e da conexão de Internet. São destacados aspectos técnicos para auxiliar pesquisadores na seleção de equipamentos de áudio/vídeo e plataformas de videoconferência, bem como no planejamento e na realização da coleta de dados. A observação on-line pode favorecer a compreensão da complexidade das dinâmicas familiares durante o distanciamento social e, também, após a pandemia, caracterizando-se como uma estratégia de pesquisa eficaz para o estudo de famílias em diferentes contextos.

Resepsi Penggemar Terhadap Karakter Anime Shounen My Hero Academia, Attack on Titan dan Hunter X Hunter

Salah satu komponen penting dalam sebuah film atau serial animasi selain dari cerita adalah karakter. Karakter utama sebagai penggerak plot pada umumnya menjadi titik fokus dan seringkali menjadi karakter favorit dari penggemar. Dalam beberapa serial tidak jarang ditemukan adanya penggemar yang lebih menyukai karakter pendamping. Mengapa hal tersebut dapat terjadi? Belum banyak penelitian mengenai topik resepsi penggemar terhadap karakter dan topik ini sangat menarik dan penting untuk dipelajari. Masalah resepsi dalam pemahaman karakter dapat dipahami dengan pendekatan naratologi kognitif dengan teori ‘kategorisasi dan personalisasi’ oleh Schneider. Struktur simpati dari Murray Smith juga digunakan untuk secara lebih jauh melihat tingkat keterikatan penggemar dengan karakter favorit mereka. Penelitian ini akan berfokus pada karakter-karakter dari serial anime shounen yang memiliki karakter pendamping yang lebih populer dibandingkan dengan karakter utama. Dari penelitian ini, teridentifikasi enam kategori dalam resepsi penggemar yaitu kepribadian, perkembangan karakter, tujuan, desain/audio-video, jalinan hubungan antar karakter dan emosi. Penggemar yang secara berkelanjutan mengevaluasi tindakan yang dilakukan oleh karakter dan seberapa dalamnya mereka memahami emosi dan hubungan antar karakter akan berpengaruh pada rasa keterikatan penggemar dengan karakter.

A Solution Focused Approach of Delivering Virtual Paediatric Diabetes Consultations During the COVID-19 Pandemic

The onset of the COVID-19 global pandemic rapidly accelerated the use of virtual consultations into everyday practice. A solution focused approach (SFA) has been established in paediatric diabetes care, resulting in positive clinical outcomes and communication. The aim of this study was to assess feedback from paediatric diabetes patients and their parents or carers regarding virtual consultations, using a solution focused approach, in a hospital setting. An electronic survey was sent to patients following their virtual consultation. Of those surveyed, 86% recommended video consultations to be part of their diabetes care. Qualitative data showed reduced travel time, comfort, reduced need for parking and convenience as the highest areas improved through video consultations. Clinical care was shown to be positive and addressed patients concerns, the majority of respondents (84%) reported that the appointment was about what they wanted it to be about. Using the solution focused model helped overcome the challenges faced with virtual consultations particularly with concerns surrounding safeguarding issues, confidentiality, audio/video difficulties and also helped to support the patient journey.

Retroalimentación en la educación remota en el nivel secundaria de la Educación Básica Regular

La interrupción de las clases presenciales en las diversas instituciones educativas conllevó a poner en marcha la educación remota que trajo consigo muchos cambios, entre ellas, el modo de evaluar y proporcionar la retroalimentación a los estudiantes, por tal motivo, la presente investigación tuvo como objetivo general analizar cómo se lleva a cabo la retroalimentación de evidencias de los estudiantes en tres escuelas del nivel secundaria de la Educación Básica Regular ubicadas en el departamento de Lima, Perú. Para tal propósito, esta investigación se apoyó en el paradigma hermenéutico interpretativo, bajo el enfoque cualitativo de tipo básico; el instrumento que se usó fue encuestas semiestructuradas las cuales se aplicaron a docentes y estudiantes de tres escuelas diferentes. De ellas, se halló que los docentes realizan la retroalimentación descriptiva y reflexiva de forma constante; y para ello, hacen uso del aplicativo WhatsApp porque permite mandar mensajes en diversos formatos: audio, video y escrito. Además, se identificó que son los docentes quienes mayormente llevan a cabo la retroalimentación y algunas veces los padres ayudan a que los estudiantes manden sus evidencias.
