Table 10 Students’ comments on strengths and weaknesses of the two MAR applications

From: Evaluating system usability of mobile augmented reality application for teaching Karnaugh-Maps

System

Strengths

Weaknesses

Keypad-based MAR

Good innovation for future engineering education

System acts as a self-guiding tool and helps us in correcting our answers

Good approach for self-evaluation

It helped to understand k-map, which is a complex topic that is hard to grab through traditional teaching

It transforms the traditional teaching to game-based teaching

Enhance the UI of the application so that interaction could be easy with pushbuttons

Multiple Marker-based MAR

Provides end to end knowledge of K-Map

Self-guiding to understand complex topics

Could enhance the learning skills of the students by transforming learning into game-based learning

System is challenging to manage. If the paper is folded, then the system does not work properly

Provides a lot of flickering effects
