A Seminar on TOUCHLESS TOUCHSCREEN. Presented By ANNEM ABIJITH REDDY 20S11AO402.

CONTENTS. Introduction. History. Working. Applications with Explanation.

INTRODUCTION. Touchless Touchscreen is technology that uses gesturing as form of input. It has no need of touching screen. This technology is high-end technology, that uses hand waves and hand flicks. Objective behind building such technology is making it even more comfortable and convenient for users to use their devices. It does not need touching of screen rather system detects hand movements in front of it by making use of various sensors. This technology looks visually fascinating and is depicted in various Sci-fi movies such as Minority Report and Matrix Revolutions..

HISTORY. The idea of the touchscreen interface was recorded in October 1965 when an engineer in Malvern, England, specifically at the Royal Radar Establishment, aimed to develop a touchscreen to aid traffic control. His name was Eric Arthur Johnson.

WORKING.

TOUCH SENSORS. A touch sensor is an electronic sensor used in detecting and recording physical touch. Also known as tactile sensors, it’s a small, simple, low-cost sensor made to replace old mechanical switches we seen in the past..

How does touch sensor work? Working principle. A touch sensor works like a switch, where when there’s contact, touch, or pressure on the surface of a touch sensor, it opens up an electrical circuit and allows currents to flow through it..

CONTROLLER. The controller is a small PC card that connects between the touch sensor and the PC. The controller determines what type of interface/connection you will need on the PC..

DRIVERS. The driver is a software that allows the touch screen and computer to work together Most touch screen drivers today are a mouse- emulation type driver..

SOME OF APPLICATIONS WITH EXPLANATION. Healthcare: Touchless touchscreens are used in healthcare settings to control medical equipment, access patient records, and interact with digital displays without physical contact. This helps reduce the risk of cross-contamination in sterile environment Automotive: Explanation: Automotive applications of touchless touchscreens include infotainment systems, climate control, and navigation. Drivers and passengers can make selections and adjustments without physically touching the screen, enhancing safety and convenience. Manufacturing: Explanation: In manufacturing, touchless touchscreens enhance human-machine interaction on the factory floor. Workers can control machinery and access information through gestures, improving efficiency and safety..

ADVANTAGES. Hygiene Durability Accessibility Weather Resistance Enhanced Security Reduced Maintenance User Experience Customization Contactless Payments.

DISADVANTAGES. Power Consumption Privacy Concerns False Inputs Security Vulnerabilities Limited Range High cost.

FUTURE SCOPE. The future scope of touchless touchscreen technology is promising, with potential applications in various industries. These touchscreens, often utilizing gesture recognition and haptic feedback, can revolutionize human-computer interaction, making them more hygienic and intuitive. In healthcare, touchless touchscreens can reduce the spread of germs on medical devices. In automotive, they can enhance driver safety by enabling gesture-controlled interfaces. Additionally, touchless touchscreens have the potential to transform retail, gaming, and public kiosks, offering more engaging and sanitary user experiences. Advancements in this technology are likely to drive its adoption and further innovation in the coming years..

CONCLUSION. In conclusion, touchless touchscreen technology represents a promising evolution in human-computer interaction. Its potential applications in various industries, including healthcare, automotive, retail, gaming, and public kiosks, offer more hygienic and intuitive user experiences. The reduction of physical contact with screens can improve public health and safety, making it especially relevant in a post-pandemic world. As this technology continues to advance, its adoption is expected to grow, leading to further innovation and integration into our daily lives..
