1 INTRODUCTION
The newly proposed project for the Napier Lion’s Gate includes a more user-friendly
mobile phone application with enhanced interactivity which is geared to give the visitors of the
campus a more interactive application to get to know the campus garden. To make this a reality,
the smartphone application has been proposed to have a new set of requirements that include the
inclusion of advanced technologies such as augmented reality, virtual reality and the new field of
Internet of Things. Some of the key features of the app include an interactive campus map, a
feature for visitors to schedule their visits to the campus and have a 360 degrees view of the
campus buildings and infrastructure and garden [1]. Through the application, one is able to
display detailed information about plants in the vicinity and their corresponding species. This is
made possible due to various camera functionalities built into the app and inclusion of proximity
sensors to correctly identify the plants [2].
The underlying architecture of the app is built on the Vufuria SDK which is normally
used to build Augmented reality applications for mobile devices. The app is secured by an
interactive login screen where users such as students and the campus staff can securely log in and
once authorized, they will be presented with a simplified version of the campus moodle. In this
moodle, the users can view the various courses offered by the campus, the status of various
modules and the student is given the ability to choose different options for taking modules, either
of trimester basis. Since AR and mostly IoT forms the bulk of the application, different student
and staff will be presented with a different view which is customized for their needs [3].

Augmented reality has been a growing field in the technology industry. It comprises of a
superimposed image generated by a computer on a view of a real-world object. The general
effect is a more composite view of the object [4]. The above has been made possible, thanks to
the processing of data generated by the system such as audio-visual, graphical and GIS. Several
research has been done in this field and the overall effect is the presentation of-of a blend of the
real object and computer-generated images to give the user a better experience with the real-life
objects [5]. This has made the virtual and real objects to exist in the same space within the
application.
The IoT, on the other hand, is made of devices and other information gathering objects
which are able to seamlessly communicate with each other and share data. This has increased the
potential of IoT devices to numerous use cases [6].
The combination of the two technology has provided the app with the ability to identify
the various tree and tree species in the campus garden, provision of a brief summary and the
potential benefits of the plant is included in the augmented view. The information is presented to
the user in a 3-dimensional space to increase more interactivity [7].
2 DESIGN APPROACHES
The design principle used in this app is making AR part of the design from the ground up
and the software mainly focus on AR. The additional communication features are implemented
using the IoT in the design [8]. The overall design of the app is as shown below,
