Augmented reality refers to the combination of computer-generated objects with real world environment. This technology is empowered by the evolution of hardware and software in the past decade. Virtual objects are placed through device screens in a user’s environment relying on the device camera and capability of graphics hardware. This advancement opens a wide horizon for application development in the field of entertainment, education, medical, etc.

One of the main advantages of augmented reality (AR) is in the treatment of various phobias though exposure treatment. A phobia is characterized by irrational fear or reaction to a normal situation. Thus, gradually exposing patients to their phobias helps in reducing their uncontrolled reaction and aids in reducing their fear of their respective phobia. Herpetophobia is the extreme fear from aversion reptiles such as lizards.  The lizard phobia is a common form of phobia amongst people.

In this article, an application of lizard phobia exposure treatment is proposed to help patients. The proposed application relies on marker-based AR. This is implemented using Visible marker AR system (VMARS) and Invisible marker AR system (IMARS), comparing the results of both systems to a group a subject to identify the best approach for Herpetophobia treatment.
