Development of Qibla Direction Cane for Blind Using Interactive Voice Command

Blind person is someone who has visually impairment. Cane is a tool aid used to assist their daily activity. A conventional cane still have limited function in detection obstacle and hole so not all activity are helped using cane. One of difficult experience is to determine the direction of qibla whenever they will pray. This research develop function of cane as a tool that can determine the direction of qibla by voice command interactively. Prototype response to user command in the voice form. Prototype using Raspberry Pi 3 as Processor, HMC5883L as compass sensor, and microphone for voice command input. The voice command from the system is heard using earphone. The test result show the system can recognize the voice command properly in noise free environment. While in noisy environment, system can recognize voice command only 20% and 40% for 10 times testing. This system also can recognize voice command with different types of sound such as male and female voice.
