Abstract: CAMAMA, MARCK IVAN R and CRUZADO, GEONEL, V., Development of Microcontroller-based Guiding Stick. Undergraduate Thesis. Bachelor of Science in Computer Engineering. Cavite State University, Indang, Cavite. December, 2016. Adviser: Ms. Emeline C. Guevarra. The study was conducted to develop the microcontroller-based guiding stick for visually impaired individuals. The project aimed to help visually impaired individuals in environment navigation without assistance. The general objective of the study was to develop a microcontroller-based guiding stick. The study specifically aimed to: design and modify the standard quad cane; integrate the microcontroller, voice kit, ultrasonic sensors and Frequency Modulation broadcaster; develop the arduino program in programming the microcontroller of the device; test and evaluate the device through: technical testing and user acceptance in terms of operability or user interaction, reliability, accuracy, functionality, safety and usability; and conduct a cost computation of the device. The materials used in the study were: microcontroller unit, voice kit, ultrasonic sensors, FM broadcaster and a wireless headset. Microcontroller-based Guiding Stick can able to inform the visually impaired in which direction to go and determine certain conditions of obstacles like ascending staircase, descending staircase and a dead-end obstacle. An array of ultrasonic sensors made it possible to sense the surroundings and by means of radio communication between the wireless headset and FM broadcaster, user is notified by the audio feedback. Technical evaluation proves that the device was functional in terms of its accuracy, responsiveness and correctness. On the other hand, in the actual evaluation of the device with the visually impaired individuals, the device did not perform efficiently. Out of three trials in the simulated maze, two trials failed and the subjects were not able to reach the finish point and experienced many collisions in the simulated environment. It was also found that the device has the potential to be used effectively by the visually impaired who acquired their blindness in later stage of their life provided that they will have a proper training in using the device while navigating in the physical environment. Different factors that were exhibited by the participants attributed to the above mentioned results. These include familiarity in spatial orientation or direction, experience of participants in cane usage, proper inclination of the cane when in use, demographic profile and the speed of the participant while travelling in the maze. These factors therefore affect the results of the evaluation and for the device to perform efficiently, the user needs proper training in using the device. Likewise, the acceptability of the unit gave a 4.44 on operability, 3.33 on reliability, 3.27 on accuracy, 4.33 on functionality, 4.20 on usability and 4.58 on safety The study met its objectives and in order to be used the device efficiently, the user needs to undergo a proper training. The microcontroller-based guiding stick had a total cost of P 8,165.00.
