A Brief Look At Hallucinations In VR Applications

As a teenager I was fascinated with LSD purely as a consequence of my love of The Beatles and its alleged association with songs such as ‘Lucy in the Sky with Diamonds‘ (I say ‘alleged’ because all Beatle fanatics know that this song got its’ title from a drawing by John Lennon’s son Julian and that lyrically the song was inspired by the writings of Lewis Carroll, the creator of Alice in Wonderland [AIW], a book which gave its’ name to AIW Syndrome that I examined in a couple of previous blogs).

 

When I first started teaching my ‘Addictive Behaviours’ module back in 1990, almost all my lectures concentrated on drug addictions (as opposed to behavioural addictions which now take centre stage in my teaching), and it was my session on hallucinogenic drugs (also known as psychedelic drugs) that was always the most fun to teach and the topic that students appeared to be most engaged in. Like many of my students, I have always been interested in altered states of consciousness both in my own research into addiction and the topic more generally.

The reason why I mention all these things as that I did a media interview on the hallucinogenic effects of virtual reality products. The interview was based on comments by Microsoft researcher Mar Gonzalez Franco, who said that virtual reality will soon replace the need for hallucinogenic drugs. More specifically, she was quoted as saying:

 

“By 2027 we will have ubiquitous virtual reality systems that will provide such rich multi-sensorial experiences that will be capable of producing hallucinations which blend or alter perceived reality. Using this technology, humans will retrain, recalibrate and improve their perceptual systems…In contrast to current virtual reality systems that only stimulate visual and auditory senses, in the future the experience will expand to other sensory modalities including tactile with haptic devices“.

 

Claims that VR products have the potential to induce hallucinogenic experiences have already started appearing in the media. A recent story in the Daily Mail reported that there was already a VR app (SelfSound) that claimed it can reproduce the effects of hallucinogenic drugs and plays on the neurological phenomena known as synaesthesia and that a “program is used to promote mediation through creating abstract reality [and] plays face-melting music with synesthetic DMT-style visualizations uniquely generated in response to [a person’s] voice”. (DMT is an abbreviation for dimethyltryptamine, a powerful hallucinogenic drug).

 

Over the last seven years, I have published a series of studies with Dr. Angelica Ortiz de Gotari (some of them listed in the ‘Further reading’ section below) showing that hallucinations are common among video gamers in our working examining Game Transfer Phenomena (GTP). Therefore, it’s no surprise that VR games can do the same thing. We have reported that visual and auditory hallucinations are commonly experiences by regular videogame players.

 

For instance, one of our studies published in the International Journal of Human-Computer Interactionfound that some video gamers experience altered visual perceptions after playing (e.g., distorted versions of real world surroundings). Others saw video game images and misinterpreted real life objects after they had stopped playing. Gamers reported seeing video game menus popping up in front their eyes when they were in a conversation, or saw coloured images and ‘heads up’ displays when driving on the motorway.

 

Our study analysed 656 experiences from 483 gamers collected in 54 online video game forums. Visual illusions can easily trick the brain, and staring at visual stimuli can cause ‘after-images’ or ‘ghost images’ among videogame players. We found that GTP were triggered by associations between video game experiences, and objects and activities in real life contexts. Our findings also raised questions about the effects of the exposure to specific visual effects used in video games.

 

We also reported that in some playing experiences, video game images appeared without awareness and control of the gamers, and in some cases, the images were uncomfortable, especially when gamers could not sleep or concentrate on something else. These experiences also resulted in irrational thoughts such as gamers questioning their own mental health, getting embarrassed or performing impulsive behaviours in social contexts. However, other gamers clearly thought that these experiences were fun and some even tried to induce them.

 

Visual experiences identified in GTP show us the interplay of physiological, perceptual and cognitive mechanisms and the potential of learning with video games even without awareness. It also invites us to reflect about the effects of prolonged exposure to synthetic stimuli and the challenges that the human mind affront due to the technological advances that are still to come. However, because we collected our data for most of our published studies from online video game forums, the psychological profile of the gamers in our studies are unknown. However, different gamers reported similar experiences in the same games.

 

This highlights the relevance of the video games’ structural characteristics but gamers’ habits also appear to be crucial. Some gamers may be more susceptible than others to experience GTP. The effects of these experiences appear to be short-lived, but some gamers experience them recurrently. It goes without saying (but I’ll say it anyway) that more research is needed to understand the cognitive and psychological implications of GTP. Most of these GTP experiences are viewed positively but a small minority of players find them detrimental.

 

Whether such hallucinations – either in typical videogames or VR videogames – can be induced on demand is debatable. Very few players in our own research said they were able to induce hallucinations. At present, we simply don’t know what the long-term effects of VR gaming will be and that goes for VR-induced gaming hallucinations too. It may be the case that VR induced hallucinogenic states will be ‘safer’ than ones induced by psychedelic drugs as there is no ingestion of a psychoactive substance, but that’s just speculation on my part.
