Real-Time Emotion Recognition Using Raspberry Pi

  • Unique Paper ID: 171292
  • PageNo: 3836-3839
  • Abstract:
  • Emotion recognition has become a critical area of research with applications in healthcare, security, and human-computer interaction. However, implementing real-time emotion recognition systems on low-cost and resource-constrained devices remains a significant challenge. This paper presents a lightweight, cost-effective solution for emotion recognition using a Raspberry Pi platform. The proposed system employs a camera module to capture facial images and utilizes deep learning techniques for emotion classification. A Convolutional Neural Network (CNN) model is trained on the FER2013 dataset and optimized for deployment on the Raspberry Pi. The system achieves real-time performance with minimal latency while maintaining competitive accuracy. Experimental results demonstrate the effectiveness of the model in recognizing six basic emotions: happiness, sadness, anger, surprise, fear, and neutrality. The lightweight design and portability make the system ideal for applications in remote monitoring and embedded systems. Future work will focus on improving accuracy with multi-modal inputs and expanding the system's adaptability to diverse environments.
