Developing affordable and privacy-aware smart home applications remains a challenge. Existing camera-based and sensor-based solutions often raise concerns about cost and user privacy. This paper proposes a low-cost WiFi-based sensing system utilizing ESP32 microcontrollers and Jetson Nano edge devices for human activity recognition (HAR) within smart homes. The system captures Channel State information (CSI) data using an ESP32-based WiFi transmitter and receiver, eliminating the need for expensive hardware while ensuring privacy preservation. A mix of conventional machine learning and deep learning models are evaluated on the obtained dataset, achieving an accuracy of up to 95.57%. The best-performing model is then deployed on the Jetson Nano edge device for efficient activity classification and high throughput. Furthermore, the system seamlessly integrates with existing communication protocols such as Message Queuing Telemetry Transport (MQTT), and provides a user-friendly interface for visualization. We demonstrate the effectiveness of our approach by achieving accurate HAR using a single transmitter-receiver pair, highlighting its practicality and scalability potential. This work aims to further exploration of WiFi sensing technology for smart home applications by enabling cost-effective and privacy-preserving HAR.

In this paper, we explore the design and evaluation of feedback for graphical perception tasks, called VisQuiz. Using a quiz-like metaphor, we design feedback for a typical visualization comparison experiment, showing participants their answer alongside the correct answer in an animated sequence in each trial, as well as summary feedback at the end of trial sections. To evaluate VisQuiz, we conduct a between-subjects experiment, including three stages of 40 trials each with a control condition that included only summary feedback. Results from n = 80 participants show that once participants started receiving trial feedback (Stage 2) they performed significantly better with bubble charts than those in the control condition. This effect carried over when feedback was removed (Stage 3). Results also suggest an overall trend of improved performance due to feedback. We discuss these findings in the context of other visualization literacy efforts, and possible future work at the intersection of visualization, feedback, and learning.
