Implementation of Location Based Service on Monito ring System of Visually Impaired Position with A-GPS Method

摘要

Disability is a deficiency in physical, cognitive, intellectual, mental, sensory, developmental, or combination of it results in limitations on individual abilities. One of them is visually impaired. The visual impairment must face many limitations in everyday life such as visibility and often get lost when going through an environment that is not familiar to them. This study discusses the implementation of location-based services in the monitoring system of visually impaired position using the A-GPS method by sending a coordinate data of the position of the visually impaired through internet connection, which will be stored in the database, so that the position of visually impaired people can be identified and displayed on an Android-based monitoring application. From testing, the results obtained that all the functional requirements of the system were successfully met and from the results of the test accuracy obtained from the questionnaire given to users who have used this prototype, obtained a value of 83.33%, which means the accuracy and functionality of the prototype in the study this is in fair category.
