Smart Internet of Things (IoT) devices are on the rise in popularity, with innovative use cases and applications emerging every year. Including intelligence in these novel systems presents the challenge of integrating interaction and communication in scenarios where traditional interfaces are not viable. Hand Gesture Recognition (HGR) has been proposed as an intuitive Human-Machine Interface, potentially suitable for controlling several classes of devices in the context of the Internet of Things. This paper proposes a low-power in-ear HGR system based on mm-wave radars, efficient spatial and temporal Convolutional Neural Networks and an energy-optimized hardware design. The design is suitable for battery-operated devices, with stringent size and energy constraints, enabling user interaction with wearable devices, but also suitable for home appliances and industrial applications. The proposed machine learning model is characterized thoroughly for robustness and generalization capabilities, achieving 94.9% (single subject) and 86.1% (Leave-One-Out Cross-validation) accuracy on a set of 11+1 gestures with a model size of only 36 MB and inference latency of 32.4 ms on a 64 MHz Cortex-M33 microcontroller, making it compatible with real-timeapplications. The system is demonstrated in a fully integrated, miniaturized in-ear device with a full-system average power consumption of 18.4 mW, a more than 6x improvement on the current stale of the art.

In recent years, the development of self-organizing and autonomous behaviors for unmanned aerial vehicle (UAV) swarms has increased significantly. Being flexible, scalable and robust, UAV swarms bring many advantages for future applications. However, these properties might also be used for malicious or dangerous applications like autonomous target-oriented attacks. To date, defense includes strategies like fighting the attackers with a defender swarm or exploiting hardware devices like nets and jammers to stop the attackers. These solutions increase the risk on collateral damage even further. To the best of our knowledge, research is lacking intelligent countermeasures against attacking UAV swarms which limit the damage as much as possible. In this paper, we explore how to invert a robust UAV swarm behavior by inducing defender UAVs into an attacking UAV swarm with the goal to mislead the swarm's mission. Via simulations, we model two different swarm behaviors and explore how to invert them with disguised UAVs deflecting the entire swarm.

Augmented reality (AR) is a cutting-edge technology that combines digital content with the real environment, resulting in improved user experiences across several fields. Marker identification algorithms are crucial in augmented reality (AR) applications since they enable precise placement of virtual objects onto the actual world. This study investigates a wide range of techniques for identifying markers, including both conventional image processing algorithms and cutting-edge machine learning models. This study employs comparative analysis to precisely define the strengths and limitations of each technique, providing significant insights into their suitability in various scenarios. The research analyses three main methodologies: template matching, feature detection, and deep learning-based techniques. It offers insights into their individual performance measures, including accuracy, speed, robustness, and scalability. Empirical evidence and research substantiate the efficacy of these methods in several fields, such as gaming, education, healthcare, and manufacturing. The research showcases significant progress while simultaneously highlighting unique constraints, such as the limited availability of various datasets, processing limitations, and the difficulties presented by dynamic augmented reality (AR) environments. In future research, the focus will be on improving current strategies to overcome these limits and investigating hybrid approaches that combine the characteristics of multiple methodologies. The combination of interdisciplinary collaboration and technological breakthroughs such as edge computing and 5G networks has the potential to improve the efficiency and feasibility of marker identification systems in augmented reality (AR). This research finally enhances the comprehension and utilization of marker identification in augmented reality (AR), hence facilitating inventive encounters and imaginative applications in diverse domains.

A new application has been developed for remote PhotoPlethysmoGraphy (rPPG) tests in real-time using a low-cost laptop or smartphone cameras. This offers a non-contact and convenient solution for heart rate (HR) monitoring, which doctors can use to view all recorded rPPG signals. The application uses a new heart rate estimation method developed from facial videos. It employs skin pixel semantic segmentation and signal processing techniques, including a deep learning model to detect skin pixels from non-skin pixels. The spatial RGB means of the segmented skin pixels are used to extract the rPPG signal, which is then post-processed to remove outliers and calculate the heart rate. The proposed rPPG-based heart rate estimation method has achieved a mean absolute error of +/- 2.5 bpm, comparable to HR sensors. This low-cost and convenient solution for heart rate monitoring holds promise in medical and biometric applications, providing a new approach to health monitoring.
