Gesture operated security lock

This project allows you to store and use your own gesture to unlock a security lock. This can be especially useful for people with physical disabilities particularly in their fingers. The attractive feature of the project is that the user makes the pattern in the air and not on any surface. The pattern can be change any number of times and also saves you from the hassle of carrying a key to unlock locks. The gestures are captured by using four infrared sensors placed in the box within the range from 10 to 80 cm. The analog output obtained from the infrared sensors is fed to the internal ADC of the microcontroller, in this case its Atmega 128p, which maps the corresponding analog readings to the equivalent digital output.

The Fantastic Gesture Recognition Based on Scratch Inputs

The gesture recognition technology has been known as a way for computers to understand human body language. It’s a basic topic in computer science and language technology with the main goal of interpreting human gestures via mathematical algorithms. Speaking about gestures, it can be originated from any bodily motion, but it’s mostly concentrate on the face or hand. The major focuses in the gesture recognition include emotion recognition from the face and hand gesture recognition. Many researchers have been using cameras and computer vision algorithms to interpret sign language. Honestly, the gesture recognition technology allows the users to interface with the machine and interact naturally without need any additional mechanical devices. It’s possible to point a finger at the computer screen, by using the gesture recognition concept, so that the… Continue reading
