KARLI – Kidfriendly Augmented Reality Learning Interface

Maintaining a healthy body and being able to make healthy decisions is hardly possible if we do not have basic understanding and knowledge of how the human body and its organs work and what they need for continuing their effective behavior. Having your mind set on healthy choices should start at the children’s age – and using the setting of primary schools is a valid way of enabling people with health knowledge.  

And this is where KARLI comes into action! 

KARLI is an augmented reality app for in-school use and is meant to enrich the way children in primary school are learning about the human body, its anatomy and its functions. The focus has been set on “Primary Level II” (children aged 8 to 10 years). In addition to an extended literature research, numerous interviews with teachers and teaching students have been performed to gain insights into existing systems and didactic needs for this age group. This made it possible to develop an “age-appropriate” user-interface as well as a “kidfriendly” user-interaction design and content, which perfectly support knowledge transfer. 

A main goal of KARLI is to enable students to gain a 360-degree insight into the human body by exploring certain body parts and functions via augmented reality. The whole concept of KARLI is based on the idea of letting children explore the new information presented to them independently. Therefore, we offer our 3D augmented reality app (containing the main learning material and a quiz for check-ups) as well as a worksheet for triggering the AR mode and summarizing the teaching content. The use of augmented reality in education is meant to lead to a better understanding of the subject, of promoted transfer into long-term memory, better collaboration and increased motivation of the students.  

The prototype of KARLI (developed with Adobe XD) contains the visualization of a possible sequence of events within the first implementation of KARLI – the human heart. The kids are meant to get a feeling of how the human heart looks and works, explained with detailed graphs, images and mini-games. After a successful implementation in Unity, adding other organs or structures of the human body could be taken into consideration. 

For the implementation the project group used the following programs: 

  • Unity & AR Core 
  • Autodesk Maya 2018 
  • Adobe XD 

In winter term 2019, KARLI will be tested and evaluated together with a partner school, the primary school Neuhofen an der Krems in Upper Austria. Students of the third- and fourth-class level will be able to test and use the application for a certain test period, followed by filling in a questionnaire about user and learning experience as well as user satisfaction. 

For taking KARLI onto the next level, the project group submitted their innovative idea to funding within the call for concepts of “OeAD / Innovationsstiftung für Bildung”. The new approach of setting the focus on children and their special needs in learning combined with the use of digital technologies in primary schools has convinced the jury: out of over 70 innovative projects, KARLI was chosen to be one of the best for entering the online voting.
