Initially, we should concentrate on key user personas: those currently visiting the zoo and those considering a future visit. These individuals may include families, school groups, or solo visitors. Their main requirements likely include: information about animals, guidance for navigating the zoo, purchasing tickets, and opportunities for enjoyable learning experiences. The suggested features are as follows: Information Database: An extensive, interactive repository of information on each animal, covering aspects such as behavior, habitat, diet, etc. To enhance engagement, it could also incorporate an animal-themed quiz. Augmented Reality (AR) Functionality: Visitors could use their camera to view an exhibit and receive additional overlay information about the animal. Interactive Map and Navigation: Provide maps of the zoo equipped with GPS-enabled navigation to assist visitors. The map could highlight nearby amenities such as restrooms and dining areas. E-Tickets: Facilitate ticket purchases through the app for convenience, minimizing wait times. Event Information: Offer details about feeding times, shows, and other activities taking place at the zoo. The app could serve the zoo by generating advertising revenue, increasing the time visitors spend on the premises, and potentially encouraging more frequent visits. It would also support the zoo’s educational objectives. In terms of scalability, the app should be designed modularly to allow for the addition of new features. For sustainability, it can adopt eco-friendly practices, such as promoting e-ticketing to lessen paper waste.
