    This study investigates the factors influencing the adoption of AI-driven chatbots for mental health support among university students in Malaysia, using the Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) as the guiding framework. In particular, the efficacy and efficacy of the performance expectancy (PE) and social influence (SI), facilitating condition (FC), and habit (HT) on adopting AI-driven chatbots as a mental support mechanism in universities in Malaysia is investigated. Quantitative methodology was employed, whereby the researchers collected 391 valid reactions of an online survey launched among students in the universities of Malaysia. Data were analysed using SPSS, with Pearson Correlation and Multiple Regression Analysis applied to assess the relationships between variables. The results indicate that performance expectancy (PE), social influence (SI), and habit (HT) are significant factors, and the facilitating condition (FC) is insignificant in the adoption of AI-driven chatbots to support the mental health of university students in Malaysia. This knowledge has practical recommendations that could be offered to universities, developers, and policymakers who intend to roll out student support services with AI-powered mental health tools. The research then ends with future research options and strategies to be used to increase adoption in various educational backgrounds.

    This project introduces a Supermarket Shopping Assistant designed to support Visually Impaired (VI) individuals in performing grocery shopping independently. Shopping in supermarkets presents major challenges for VI users, as identifying products, locating items on shelves, and reading packaging information typically require external assistance. To address this gap, the proposed system integrates computer vision, optical character recognition, and text-to-speech technologies into an Android mobile application that provides real-time product recognition, hand guidance, and product information retrieval. The system architecture was developed around two complementary approaches for product identification: a product detection model using Roboflow API, and a text detection approach leveraging Google Cloud Vision API. While the detection model achieved high accuracy in recognizing standard grocery products, the text detection approach provided greater robustness by always generating an output, even when object detection failed. In addition, hand detection was implemented using MediaPipe to guide the user’s hand toward the detected product through audio feedback. Once the item was acquired, the user could capture its packaging details, which were processed using OCR and summarized by the Gemini API before being read aloud, ensuring clarity and conciseness. Evaluation results demonstrated that the system successfully fulfilled its objectives, with each module performing reliably under controlled conditions. Although challenges such as dependence on cloud services were noted, the system still provided a practical and accessible solution. By enabling VI individuals to identify, reach, and evaluate grocery products independently, this project contributes to enhancing daily autonomy and highlights the potential of AI-driven assistive technologies to promote inclusivity in society

    Get PDF
    This project develops a blockchain-based subsidy program delivered as a web application to enhance the efficiency and transparency of government subsidy distribution. By leveraging blockchain technology, the system ensures secure and auditable allocation of funds, thereby strengthening public trust in subsidy mechanisms. The research methodology involves a review of existing blockchain applications in the public sector, followed by phased development using Visual Studio Code, Supabase, and the Ethereum Sepolia Network. The novelty of this work lies in its integration of multiple innovations. First, an ERC-20 token, MMYRC (Mock Malaysia Ringgit Coin), is created and airdropped to eligible citizens to demonstrate that the entire distribution process can be conducted on-chain. Second, eligibility is determined through a rule-based scoring matrix supported by Retrieval-Augmented Generation (RAG), providing decisions that are both transparent and explainable from government datasets. Third, lightweight AI agents (smolagents) implement a dual-analysis framework that combines the RAG-based approach with a formula-driven burden score, allowing for systematic comparison between interpretability and flexibility in eligibility determination. Finally, zero-knowledge proofs (ZKPs) are explored as a privacy-preserving mechanism, enabling citizens to prove their income bracket (B40, M40, T20) without disclosing precise income data. A mock trusted setup with the Inland Revenue Board of Malaysia is used to verify digitally signed income information, ensuring authenticity while preserving privacy. The expected outcome is a fully functional prototype web application that reduces administrative overhead, improves the auditability of subsidy allocation, and enhances the effectiveness and public legitimacy of government subsidy programs

    Arfict: Indoor navigation mobile application using augmented reality (AR) for FICT

    Get PDF
    As commercial and educational institutions grow more complex, indoor navigation has become essential. Traditional GPS navigation, effective outdoors, struggles indoors due to signal interference from walls and ceilings. This is even more significant in large, multi-floor buildings such as university campuses, where GPS signals are blocked. Additionally, 2D maps are not capable of providing real-time, adaptive directions, leading to inefficiency and user frustration. Hence, the ARFICT project aims to develop an Augmented Reality (AR)-based indoor navigation system for the FICT building at UTAR, providing a real-time, interactive navigation experience that enhances wayfinding in complex indoor environments. The project's contribution goes beyond UTAR, forming a basis for AR-based navigation in various large indoor environments, such as shopping malls, airports, and hospitals. The use of external hardware, like Bluetooth beacons, is eliminated, thus offering an affordable solution for navigation in multi-floor buildings. The system employs a marker-based localisation method using QR codes decoded with the ZXing library to establish the user’s initial position. Navigation paths are optimised using the A* algorithm, while ARCore integrates sensor data from the device’s gyroscope and accelerometer to enhance tracking accuracy. Users are guided with AR-based path visualisation, distance indicators, and voice instructions, ensuring intuitive and efficient navigation across multiple floors. In summary, this project successfully developed an AR indoor navigation application to provide advanced indoor navigation, improve efficiency, and provide a reliable wayfinding for students, staff, and visitors in the multi-floor FICT building, enhancing the user experience in complex indoor environments

    Video surveillance: explosion detection

    Get PDF
    The proliferation of surveillance technologies has emphasised their pivotal role in enhancing public safety by monitoring and detecting anomalies in real time. Among the anomalies, explosions present a grave threat due to the potentially resulting major loss of life, widespread panic and significant destruction of property. However, traditional surveillance systems are limited by their reliance on human monitoring, which is susceptible to oversight due to fatigue or distractions. Thus, this research focusses on developing an intelligent explosion detection surveillance system that is capable of early and accurate explosion detection. Explosions typically happen in a very short timeframe, often just a few seconds, leading to significant challenges for the rapid and accurate identification of explosions' unique visual patterns immediately. Hence, this study proposes to embed computer vision and advanced image processing algorithms, such as Motion History Images (MHI) and Motion Energy Images (MEI), into the intelligent explosion detection video surveillance system. By leveraging three motion-based variables, including motion ratio, new pixel ratio and optical flow values, together with three detection approaches, namely global detection, non-eroded detection and eroded detection, the system demonstrates the effectiveness of motion based methods in detecting explosions at an early stage with acceptable performance. Eventually, this approach aims to minimise explosions' damage by enabling immediate responses, preventing the spread of fires and the occurrence of secondary explosions

    Get PDF
    Floods stand as some of the most devastating natural disasters because they provoke enormous damage, the loss of human lives, and the disruption of communities. Despite the advancement of flood management systems, most of the existing solutions experience problems regarding real-time flood information, inefficient relief center coordination, and ineffective evacuation processes, which delay responses and poor resource allocation. This project introduces FloodGuard, which a comprehensive flood management system application to address the existing gaps and enhance real-time disaster response. One of the key novel features is the implementation of an automated relief center assignment algorithm, which dynamically assigns the user to a nearby relief center based on the risk assessment, proximity and capacity rather than manually searching for relevant centers. This system involved a centralized command center for administrator to review and approve flood reports, monitor real-time flood summaries and user records for better decision-making. Moreover, FloodGuard employs an innovative approach to human-scale water level measurement wherein users input their height and mark the water level on their body to generate more accurate flood depth data. Then the data feeds into a multi-dimensional risk assessment framework which calculates user priority scores based upon demographic factors, building characteristics, and real-time exposure metrics. Integrated with dynamic analysis of flood severity, the system incorporates automated risk-prioritized relief center assignment. Other features include push notifications for residents within flood zones, route guidance to centers, flood reporting and structured emergency communication systems that provide users with necessary services such as medical aid. In addition, all the submitted reports are verified by the administrator before being published to ensure reliability. Developed in React Native, Expo, and Firebase, FloodGuard demonstrates significant improvements in disaster response efficiency and community preparedness, enhancing safety and resilience from floods
