Indoor Navigation System for Accessible Friendly Services and Facilities in the Library


Acquiring information about relevant indoor locations within a facility can be challenging for PWDs with conditions like visual impairment and blindness. This can also be the case for wheelchair users who would require accessible paths to reach relevant areas within a location. The provision of indoor navigation information in facilities like libraries can help in enhancing the user journey of PWDs to efficiently access relevant areas and services. The adoption of such technology will ensure an accessible user journey experience for PWDs with various types of disabilities.
