1. Introduction

Raspberry Pi refers to a series of small single board computers developed by Raspberry Pi Foundation in the UK, aiming at promoting the education of basic computer science in schools and developing countries. This assignment requires to measure physical input values by using Raspberry Pi and display them on the screen, allowing the values to be altered by interactive operation.
Gesture Recognition is a topic of computer science and language technology, which aims to interpret human gestures through digital algorithms. The technology is considered to be a very successful technology, which provides a new type of device interaction, characterized by higher accuracy, high stability and time-saving. Gesture recognition has a prosperous application in automobiles, consumer electronics and gaming industry, that’s why Gesture Interface Glove is selected as the topic of research.
Attach the glove to the flex sensor, and drive the sensor to deform through the bending of the finger, displaying the physical input value on the screen. After calibration, simple gesture games can be realized by proofreading operation within the system. The following sections will provide a detailed description, including project structure，design (hardware and program) and product performance.
