The conventional devices such as LASER pointers, remotes, mouse and other devices are meant to offer convenience to users while operating on a projector screen. However, when using multiple devices, transitioning from one device to the other is cumbersome and defeats the purpose of using such devices. The objective is to make operations on a projector screen more interactive. In the developed model, wireless interaction with the screen is accomplished by using Arduino and Joystick Module. The joystick sends the X-Y coordinates to the Arduino, which is then transmitted to the receiver via Bluetooth module, which makes the movement of the cursor possible. The interactive screen is achieved by using an Infrared emitter, an Ultrasonic module and a camera which is positioned behind the projector screen such that it recognizes the movement of the IR rays from the emitter. The image captured by the camera is processed by MATLAB software and mimics the movements on the screen. The ultrasonic module is configured such that it allows the stylus to work only when it comes within a predefined range. These two implementations together make the projector screen interactive and also increases the productivity of the interactive process by eliminating the dependency of the user on multiple devices.

The research paper ventures through the control of projector wirelessly with smart phone. Present remotes work on IR based communication. The device to be controlled is considered as a receiver and the remote behaves as a transmitter. In case the remote is lost, the controlling becomes impossible, thus making it difficult for the user to operate the device . In this paper, authors have tried to remove this hardware dependency by controlling the infrared device using the Bluetooth technology.

Autonomous mobile robot is an integrated system which integrates many functions such as environment perception, dynamic strategy and planning, behavior control and execution. In recent years, mobile robot technology has played an important role in many fields such as industry, agriculture, medicine, aerospace and aviation. Intelligent robots require more and more real-time, adaptability and optimization for unknown environments. Only with the ability of autonomous action can they realize their value. Robot obstacle avoidance has been widely studied since the emergence of mobile robots, but at the beginning, this technology has not been studied as a separate technology. Intelligent obstacle avoidance is one of the hotspots and difficulties in the field of research. Intelligent obstacle avoidance is able to effectively avoid obstacles and reach the end point according to certain methods according to the information collected from obstacles. People usually use path planning to realize it. Path planning is used to decide how a robot walks in the environment that is the key technology to realize the intelligent robot. Path planning is used to guide the action and behavior of a mobile robot to reach its target location. According to some optimization criteria, an optimal path from the starting point to the target point can be found in the navigation range of a mobile robot, and obstacles can be avoided. The path has some characteristics, such as the shortest distance or the least time. This paper discussed the issue of obstacle avoidance of two-wheeled mobile robot based on DWA algorithm. By building maps, placing obstacles and testing the DWA algorithm on ROS, it is concluded that the DWA algorithm can be well applied in the field of robot obstacle avoidance.

Aiming at the problems of low obstacle avoidance accuracy and long obstacle avoidance time in the traditional obstacle avoidance system, an automatic reversing intelligent obstacle avoidance system based on optical fibre sensor is designed. The system hardware consists of optical fibre sensor module, power module, microprocessor, display output module and voice alarm module. The wavelet packet analysis method is used to extract the obstacle features in the process of automatic reversing. According to the feature extraction results, the optical fibre sensor is used to measure the distance, calculate the spatial position of the obstacle features in the process of automatic reversing, so as to realise automatic reversing and intelligent obstacle avoidance. The simulation results show that the maximum obstacle avoidance deviation of the designed system is 0.8 mm, which is much smaller than that of traditional obstacle avoidance systems; the obstacle avoidance response time of the proposed system is only 18 s, which is also much smaller than other systems. The proposed method exhibits higher obstacle avoidance accuracy, shorter obstacle avoidance response time, and excellent application performance.
