A recent technology known as transparent screens is transforming windows into displays. These smart windows are present in buses, airports and offices. They can remain transparent, as a normal window, or display relevant information that overlays their panoramic views. In this paper, we propose transforming these windows not only into screens but also into wireless transmitters. To achieve this goal, we build upon the research area of screen-to-camera communication. In this area, videos are modified in a way that smartphone cameras can decode data out of them, while this data remains invisible to the viewers. A person sees a normal video, but the camera sees the video plus additional information. In this communication method, one of the biggest disadvantages is the traditional screens' power consumption, more than 80% of which is used to generate light. To solve this, we employ novel transparent screens relying on ambient light to display pictures, hence eliminating the power source. However, this comes at the cost of a lower image quality, since they use variable and out-of-control environment light, instead of generating a constant and strong light by LED panels. Our work-dubbed PassiveCam overcomes the challenge of creating the first screen-to-camera communication link using passive displays. This paper presents two main contributions. First, we analyze and modify existing screens and encoding methods to embed information reliably in ambient light. Second, we develop an Android App that optimizes the decoding process obtaining a real-time performance. Our evaluation, which considers a musical application, shows a Packet Success Rate (PSR) of close to 90%. In addition, our real-time application achieves response times of 530 ms and 1071 ms when the camera is static and when it is hand-held, respectively.
This study delves into the affine formation problem within discrete-time multi-agent systems, emphasizing the significance of the fixed communication period. It explores both undirected and directed graphs to model co...

This paper investigates the problem of leader-follower formation control for wheeled mobile robots with performance constraints and safety requirements, where the working environment is cluttered with obstacles. The artificial potential function is employed to prevent the followers from colliding with other robots and obstacles, while guaranteeing the communication connectivity with their neighbors. Then, a finite-time flexible performance function is constructed to constrain the formation tracking error such that the formation tracking error converges to a predetermined region in a finite time. This feasible region expands when the performance constraints conflict with collision avoidance and/or connection maintenance constraints. As a result, the proposed finite-time flexible performance-based formation control strategy achieves a delicate balance between the performance constraint and safety requirement. The proposed formation control method also guarantees that all error signals in the closed-loop system converge to a prescribed region within finite time. Simulation results verify the effectiveness of the proposed method.
