“…Location-based services are also being utilized as assistive technology to help visually impaired persons, disabled, and elderly persons carry out their everyday activities independently (Hakobyan et al, 2013;Pulido Herrera, 2016); these assistive technologies provide assisted-living features such as personalized navigation and wayfinding, obstacle avoidance, and more (Hakobyan et al, 2013). A system developed by the Hong Kong Polytechnic University provides a smart navigation system for visually impaired students by the use of a voice function (Noorithaya et al, 2014): when the user opens the Voice Map on their device, the visually impaired students can give a command about their start point and destination (Noorithaya et al, 2014), the system receives route instructions that will generate voice output from the mobile application by calculating the iBeacons and start navigating (Noorithaya et al, 2014).…”

Location-based services in the Smart City development have been used frequently by citizens which open up a new dimension to people’s lives (Kohne & Sieck, 2014; Komninos, 2018). Location-based services are used for routing, marketing, education, emergency, and e-commerce, and there is an increasing need and demand for the applications of Smart City (Adams et al., 2003). This paper looks into one of the wireless communication technologies in location-based services i.e., Bluetooth Low Energy/iBeacon, and a case study of the “Augmented Teaching and Learning Advancement System (ATLAS)” developed by the Hong Kong Polytechnic University for teaching and learning purposes; and then demonstrates a case of using location-based services for navigation aid to visually impaired students in the Smart Campus development and future applications in relation to the developments of Smart City.

The assistance system for visually impaired people has been implemented by using ultrasonic principle to provide navigation. The presented system functions in 2 modes of operation that are obstacle recognition mode and fixed path mode. Obstacle detection mode uses grouping of ultrasonic transceivers for solid obstacle detection and water sensor to identify liquid obstacles by employing a microcontroller. The information about the obstacle is sent to the blind person via a voice mode by using android phone through Bluetooth device. In second mode which is preferably a fixed path mode the person is guided from start point to the end point for a particular path. The blind person can swap between the different modes by using the button present on the cane. Global positioning system (GPS) is used to instruct the person to move from one place to other. The projected system delivers whole direction and defence to a blind person for many situations.

“…Some of the latest technologies developed for the blind include -smart glasses [1] that can read and recognize faces, Finger reader, Blind reader, Co-robotic cane-GPS based assistive device [2] etc. These existing systems succeed in object recognition, navigation [3] but haven't achieved much in determining the exact position of an object so that the user grabs it. We have arrived at a method for determining the position of an object with respect to user's hand.…”

Visual impairment is the functional loss of the eye or eyes in which a person's eyesight cannot be corrected up to a normal level. Visually impaired people face many problems in their day to day life and the most common inconvenience is to find their personal items which are misplaced in their indoor space. With advancement in technology, normal conduction of tasks can be made possible for such cases. This paper describes a system which is a user friendly human computer interface enhanced with computer vision technology which will be able to support the visually impaired to localize and pick up objects used in their daily life. Several efforts have been taken in the past few years to improve the quality of life of such people. The aim of our system is to bridge the gap between what the disabled person wants to do and what the existing social infrastructure allows them to do.
