Parental Control Time Lock App_569
Authors: Hitanshu Bodana, Ronak Singh, Krish Patel
Abstract: The increasing immersion of children in digital ecosystems—mobile applications, virtual environments, and gamified digital spaces—has amplified concerns around excessive screen time, addictive applications, and exposure to harmful content. Traditional parental control systems rely on rigid blocking mechanisms, often creating resistance among children and lacking nuanced, interactive behaviour regulation. This paper presents a Parental Control Time Lock App, a collaborative digital parenting framework integrating real-time monitoring, application-level time budgeting, and OTP-based conditional unlocking. Developed using Kotlin (Android) and a Spring Boot backend, the system enforces usage limits and enables parents to remotely authorize temporary access by providing a secure one-time password. The application incorporates behavioural design elements to promote healthy usage rather than punitive restriction. Testing conducted across 20 families demonstrated a 32% reduction in unregulated screen time and high parental satisfaction. The study contributes to the domains of digital wellbeing, child safety, and human–computer interaction by proposing a hybrid control model that balances autonomy, security, and trust.
Development of a Low Cost 3D Printed Myoelectric Hand using EMG and ECG Signal Fusion
Authors: Ayush Kumar, Abhendra Pratap Singh, Uma Gautam, Nandini Sharma
Abstract: For amputees in underdeveloped nations, the high expenses and complexity of commercial upper-limb prosthetics continue to be major obstacle to accessibility. The design, development, and testing of an affordable, 3D printed bionic hand with a dual-sensor interface is presented in this study. This system incorporates Electrocardiography(ECG) as a secondary control modality for improved stability and mode switching, in the contrast to standard myoelectric systems that only use Electromyography (EMG) and are vulnerable to motion artifacts and false triggers. Autodesk Fusion 360 was used to design the mechanical structure, which was then made of polylactic acid (PLA) and has a tendon-driven actuation mechanism controlled by SG90 servo motors. Band-pass filtering and threshold-based algorithms are used by the control logic, which is implemented on an Arduino Uno, to handle biosignals in real time. The ECG signal successfully serves as a safety interlock, and experimental results show a system latency of about 190ms and a strong object grabbing capacity. The combination of multimodal biosignals with additive manufacturing can produce a dependable, accessible, and useful prosthetic solution, as evidence by the fact that the entire fabrication cost was kept under 10000 INR.
