Fruitify: Nutritionally augmenting fruits through markerless-based augmented reality

In the past few decades, a significant decrease in fruit consumption around the world has resulted in a hiking rate of cardiovascular diseases and obesity among youngsters. In order to address this issue, healthy eating is being recommended. However, awareness on nutritional information on fruits remain an important challenge that still needs to be addressed even though various sources in the form of books, websites and mobile applications are already available. This is also potentially due to the limited interaction and engagement with such sources. One technology that has shown to improve engagement, enhance understanding and provide a unique learning experience is Augmented Reality. However, limited work has been undertaken to provide nutritional information on fruits via this technology. As such, this paper investigates the application of AR to nutritionally augment fruits through a proposed prototype called Fruitify, before discussing the usability tests performed on the application and involving end users. As key findings, a system usability scale score of 82.1% was obtainedwhere participants expressed strong intention to utilize the tool again in the future.
