Abstract

All students and teachers with Visual Sensory Disabilities (PDSN) in the State Special School Category A (SLBN-A) Citeureup Cimahi City have been equipped with basic Mobility Orientation (OM) technical skills to be able to carry out independent activities and mobility. The OM technique uses five still-functioning senses: a white cane and a guide. Another problem from the assistant's side was that both class and dormitory teachers felt worried/anxious regarding PDSN students' whereabouts in the school environment. PKM's output for making sticks is focused on ergonomics, ease of installation, use, and functions that do not burden the PDSN. The stick will detect objects before you and inform you about them through sound (beep), vibration, or a combination. In implementing this PKM, the team carried out knowledge and technology transfer to the Instructors/Teachers as well as testing to the PDSN. This activity results in an electronic walking stick that has been tested.

Abstract

This research developed, designed, and implemented a cane prototype with the ability to identify spatial conditions, which can help the mobility of blind people in the form of decision information on choosing a path that is free from obstacles. The electronic space sensing system uses ultrasonic-type non-contact/non-visual sensors. Ultrasonic sensors are installed at three points: left, front, and right (L, F, R) of the stick. When the stick swings left-right or vice versa, each sensor will produce an array of distance data and then average it. The average distance of each point is calculated by the Left Side Square Area (LSSA) and Right Side Square Area (RSSA). The LSSA and RSSA values ​​are used as fuzzy input, a fuzzy inference process is carried out using a rule base, and defuzzification is used for decision output on the microcontroller. The system translates the decision results into sound (beep) and vibration information for the user. The results of the second experiment with blind people in two different scenarios show that the system can be an effective support during mobility in the hall and is a feasible prototype for training blind people with new O&M techniques towards the use of travel aids.
