“…These proposed solutions utilize a liquid crystal shutter that periodically chops the long-wave infrared radiation to create the necessary infrared radiation change artificially. A sensing module dependent on an optical shutter was also designed and proposed to solve the stationary human detection problem in [ 40 ]. This work shows an accurate detection of standing and moving human subjects at a maximum distance of about seven meters.…”

“…PIR sensor solutions for HIAR have also been explored in the literature. For example, the work presented [ 40 ] also extends their stationary human detection solution to activity recognition, proving 0.93 accurate at differentiating unoccupied, sitting, and walking. The work presented [ 42 ] highlights an activity recognition F-measure of 0.57 while using two traditional PIR sensors to recognize four complex activities completed at the same location.…”

Human monitoring applications in indoor environments depend on accurate human identification and activity recognition (HIAR). Single modality sensor systems have shown to be accurate for HIAR, but there are some shortcomings to these systems, such as privacy, intrusion, and costs. To combat these shortcomings for a long-term monitoring solution, an interpretable, passive, multi-modal, sensor fusion system PRF-PIR is proposed in this work. PRF-PIR is composed of one software-defined radio (SDR) device and one novel passive infrared (PIR) sensor system. A recurrent neural network (RNN) is built as the HIAR model for this proposed solution to handle the temporal dependence of passive information captured by both modalities. We validate our proposed PRF-PIR system for a potential human monitoring system through the data collection of eleven activities from twelve human subjects in an academic office environment. From our data collection, the efficacy of the sensor fusion system is proven via an accuracy of 0.9866 for human identification and an accuracy of 0.9623 for activity recognition. The results of the system are supported with explainable artificial intelligence (XAI) methodologies to serve as a validation for sensor fusion over the deployment of single sensor solutions. PRF-PIR provides a passive, non-intrusive, and highly accurate system that allows for robustness in uncertain, highly similar, and complex at-home activities performed by a variety of human subjects.

In a time when the entire world is going through a pandemic which can be curbed or substantially avoided and reduced by maintaining distance, it is crucial for every individual to follow the social distancing norms. However, it can be a challenging and daunting task to ensure safe distance all the time. Thus a Sixth Sense Jacket is a great way to keep the user mindful and alert of their surrounding without actually being alert all the time. It can not only alert the user but can also keep daily essentials such as keys and cards clean using dry sanitization. The jacket comes with a bunch of special features such as Pulse Oximeter which can be used to check vital health stats such as heart rate and blood saturation (SpO2) levels. The prime purpose of the Sixth Sense Jacket is to keep the user passively mindful of it's surrounding all the time and thus can be used in any field where it is crucial to stay alert in a given surrounding. The various domains this jacket can be used are women safety, battlefield and to add an extra sense to visually impaired people. The jacket can be a useful means to pre-empt any given danger that might befall the user and hence the name "Sixth Sense" Jacket.
