Implementação de uma luva microcontrolada para a captura de gestos

Abstract

This work presents the development of a glove to catch gestures. For the glove prototype we used 6 sensors MPU6050 type, which contains 3-axis accelerometers and 3-axis gyroscopes. These sensors have built-in 16-bit Analogue-to-Digital converters to make the conversion of instantaneous values of acceleration and tilt. The sensors have configurable precision tracks and communicate through I2C communication protocol. For control and communication with the sensors we used PAMPIUM microcontroller, described in SystemVerilog. An I2C communication interface was implemented for sending and receiving data from the sensors. The captured data from the sensors are sent to a computer, where they could be analyzed. For communicating with the computer we also implemented an RS232 interface. The communication interfaces have been described in SystemVerilog and its operation is tested by using FPGA. For a theoretical foundation, we presented topics related to communication interfaces to PAMPIUM microcontroller, sensors used and also the glove prototype. This work also brings in detail the implementation of I2C and RS232 interface and its control blocks. The communication speed of the I2C interface was close to 400k bit/ sec and a maximum communication speed of the RS232 interface is 28800 bits / second. It provided a sampling rate of 30.1 samples per second. By using glove it was possible to capture and graphically analyze some gestures. These results demonstrate that the glove motion can be used to capture gestures.
