Virtual reality (VR) is a technology that allows users to experience simulated environments through a headset and controllers. VR has been used for various purposes, such as gaming, education, training, tourism, and therapy. However, current VR systems have some limitations, such as low resolution, limited field of view, latency, motion sickness, and lack of haptic feedback. These factors can reduce the sense of presence and immersion that VR aims to provide.
To overcome these challenges, some researchers and developers are working on a more advanced form of VR, called full dive VR. Full dive VR is a hypothetical technology that would enable users to enter a virtual world with their entire consciousness, using a brain-computer interface (BCI). In full dive VR, users would not need any external devices or sensors, as their brain signals would be directly translated into actions and sensations in the virtual world. Users would be able to see, hear, touch, smell, and taste the virtual environment as if it were real.
How does full dive VR work?
Full dive VR is based on the idea of creating a neural link between the user’s brain and a computer system. The computer system would scan the user’s brain activity and send appropriate stimuli to the user’s sensory organs, such as the eyes, ears, skin, nose, and tongue. The user’s voluntary and involuntary movements would also be detected and replicated in the virtual world. In this way, the user would feel like they are actually living in the virtual world, rather than just observing it.
There are different approaches to achieve full dive VR, depending on the type and level of BCI used. BCI can be classified into invasive and non-invasive methods. Invasive BCI involves implanting electrodes or chips into the user’s brain or nervous system, which can provide high accuracy and bandwidth, but also pose ethical and safety issues. Non-invasive BCI uses external devices or wearables that measure the user’s brain activity through electroencephalography (EEG), functional magnetic resonance imaging (fMRI), or near-infrared spectroscopy (NIRS). Non-invasive BCI is less risky and more accessible, but also less reliable and efficient.
Another way to categorize BCI is by the direction of information flow: input or output. Input BCI allows the user to send commands or intentions to the computer system through their brain signals. Output BCI allows the computer system to send feedback or stimuli to the user’s brain or sensory organs. Full dive VR would require both input and output BCI to create a bidirectional communication between the user and the virtual world.
What are the benefits of full dive VR?
Full dive VR has the potential to offer many benefits for various domains and applications. Some of them are:
- Entertainment: Full dive VR could create unprecedented levels of immersion and realism for gaming, movies, sports, music, art, and other forms of entertainment. Users could explore different worlds, scenarios, characters, and genres without any physical or temporal constraints. Users could also interact with other users or artificial agents in a social and collaborative way.
- Education: Full dive VR could enhance learning outcomes and motivation for students and How Close Are We to Full Dive VR? | Tech Topics (medium.com) teachers. Users could access rich and diverse educational content and resources in a personalized and interactive way. Users could also experience historical events, cultural phenomena, scientific concepts, and artistic expressions in a first-hand and immersive way.
- Training: Full dive VR could provide effective and efficient training for various professions and skills. Users could practice in realistic and safe environments that simulate real-world situations and challenges. Users could also receive immediate feedback and guidance from experts or mentors.
- Tourism: Full dive VR could enable users to travel to any destination in the world or beyond without leaving their homes. Users could enjoy the scenery, culture, cuisine, and attractions of different places in a vivid and authentic way. Users could also meet new people and make friends from different backgrounds and regions.
- Therapy: Full dive VR could help users cope with various physical or mental health issues. Users could receive treatment or support from professionals or peers in a comfortable and confidential way. Users could also use full dive VR as a form of relaxation or stress relief.
What are the challenges of full dive VR?
Full dive VR is still a theoretical and experimental technology that faces many technical, ethical, social, and psychological challenges. Some of them are:
- Technical: Full dive VR requires a high level of accuracy, speed, resolution, bandwidth, security, and compatibility for both BCI and computer systems. Current BCI methods are not yet capable of capturing or stimulating all aspects of human brain activity or sensory perception. Current computer systems are not yet powerful enough to generate or process realistic and complex virtual environments.
- Ethical: Full dive VR raises many ethical questions regarding privacy, consent, ownership, responsibility, regulation, and governance. Who has access to the user’s brain data? How is it stored, shared, or used? Who controls the content and quality of the virtual world? How are the user’s rights and interests protected? How are the conflicts and disputes resolved?
- Social: Full dive VR could have positive or negative impacts on the user’s social relationships and interactions. How would full dive VR affect the user’s identity, personality, values, and beliefs? How would full dive VR affect the user’s communication, collaboration, and empathy with others? How would full dive VR affect the user’s sense of belonging and community?
- Psychological: Full dive VR could have positive or negative effects on the user’s mental health and well-being. How would full dive VR affect the user’s mood, motivation, attention, memory, and cognition? How would full dive VR affect the user’s self-esteem, confidence, and satisfaction? How would full dive VR affect the user’s reality testing and dissociation?
