There are still no holograms or touch interfaces that float in front our eyes, and the Google glasses are just a small step on the way.

No artificial technology is needed, only the most powerful machinery never invented, the human mind! Suddenly the real scenery of some gamers appeared tinted by colours and textures, shadows, auras around objects, menus, power bars and pixelations.


Video game images appeared passive and other times moving. Sometimes with closed eyes or with every blink of the eye, and suddenly in front of the eyes!


Visual after-effects happen due to neural adaptations. Afterimages can easily be caused by simply looking at a bright light, but the most interesting findings in this study about GTP, is that perceptual distortions and images from the games were triggered by associations between the real world and previous video game experiences.

Images appear like pieces of a puzzle in real life scenarios, like projections of thoughts that reveal the complexity of the human mind, and the interplay of physiological, perceptual and cognitive mechanism.


These altered perceptions can end in a good laugh, in creative and ludic experiences, or scary situations where some gamers have questioned their own mental health.


Gamers have also experienced cross-sensorial experiences, synesthesia-like experiences induced artificially, when auditory stimuli such as music triggered seeing video game images, and multisensory experiences when images were seen while feeling involuntary movements of fingers or legs.


Also,  gamers experienced misperceptions when for a moment they thought they saw something from the game. These experiences usually occurred when real life stimuli shared similarities with video game elements or were presented in similar contexts.


In the first Game Transfer Phenomena study, an interview study with 42 Swedish frequent gamers, participants reported seeing health bars and text boxes above people’s heads (Ortiz de Gortari, Aronsson, & Griffiths, 2011). So, I decided to investigate these experiences closer as my PhD. This new study focus particularly on gamers’ experiences related to visual cues in video games, published in co-authorship with my PhD supervisor, Dr. Mark Griffiths, comprise the analysis of 656 experiences from 483 gamers that were collected from online video games forums.  Here are the results in numbers. A total of 181 different video game titles were related with gamers’ experiences.

Updated based on a recent survey with over 2,000 gamers.

Gamers have reported similar experiences in the same games in both qualitative and quantitative studies of GTP.

77% have visualized or seeing images with closed eyes

46% have misperceived real life objects

36% have perceived environments distorted or objects

30% have seeing images with open eyes

    1. Thanks for sharing your opinion.
      Not all gamers experience GTP, but according to our studies conducted with different samples of over 1,000 participants, most gamers have experienced some form of GTP (visual, auditory, thoughts or behaviours) -at least once- at some point in their lives. GTP has been reported with over 400 video game titles.

  1. I have not heard of this and I think the only way for this to happen is if you play like for a million hours.
