Development of Voice Commands in Digital Signage for Improved Indoor Navigation Using Google Assistant SDK

One of the most challenging aspects of trying to navigate in a new indoor place can be making sense of the navigational tools available. Traditionally, static maps have been used to provide guidance to people in indoor spaces. Recently, a new category of signage has begun to gain prominence in this area: digital signage. With the advent of such devices, many approaches have been taken to provide information to people in a more useful way. Some digital signs simply provide information in a predetermined manner, while others allow for user interaction using buttons or touchscreens. Although many digital signs allow for a more dynamic display of information, few are able to easily provide custom information based on easily acquired user input. We propose a novel type of digital signage that is voice-forward, using voice input and natural language processing to allow the users to find information faster than a standard touchscreen-only modality.
