Key terminology

Virtual Reality (VR): A computer-generated simulation of a three-dimensional environment that users can interact with through specialized hardware, such as headsets, creating an immersive experience.

Augmented Reality (AR): Technology that overlays digital information, such as images or sounds, onto the real world, enhancing the user’s physical environment with virtual elements.

Extended Reality (XR): An umbrella term that encompasses all immersive technologies, including virtual reality (VR), augmented reality (AR), and mixed reality (MR).

User Interface (UI): The visual and interactive elements of a system that users interact with, such as buttons, menus, and icons in a virtual environment, helping them navigate and control the system.

User Experience (UX): The overall experience users have when interacting with a system, focusing on usability, satisfaction, and the emotional responses elicited during the interaction.

Presence: The psychological state in which users feel as if they are truly present in a virtual environment, often regarded as a key factor in the effectiveness of immersive experiences.

Exposure Therapy: A psychological treatment method where individuals are gradually exposed to trauma-related stimuli in a controlled environment to reduce fear responses, often used in VR for PTSD treatment.

Post-Traumatic Stress Disorder (PTSD): A mental health condition that develops after experiencing or witnessing traumatic events, characterized by flashbacks, anxiety, and avoidance behaviors.

Virtual Reality Exposure Therapy (VRET): A therapeutic intervention using VR to immerse patients in anxiety-inducing environments in a controlled manner to treat disorders like PTSD and phobias.

Mindfulness: A mental practice involving focused attention on the present moment, often used to reduce stress and anxiety, which can be enhanced through VR by immersing users in calming virtual environments.

Autistic Anxiety: Anxiety that is commonly experienced by individuals with autism due to sensory sensitivities, social challenges, and difficulties with uncertainty, often addressed using VR-based therapies.

Neurodiversity: The concept that neurological differences, such as autism, ADHD, and dyslexia, are natural variations in the human brain, rather than deficits, and should be embraced in VR design and experimental research.

Artificial Intelligence (AI): The simulation of human intelligence by machines, often integrated into VR to create adaptive environments that can respond dynamically to user inputs and behaviors.

Electroencephalography (EEG): A method of recording electrical activity in the brain, used in conjunction with VR to monitor cognitive load, emotional responses, and neural activity during immersive experiences.

Haptic Feedback: Tactile feedback provided through vibrations or pressure in VR environments, allowing users to “feel” virtual objects and enhancing immersion.

Brain-Computer Interface (BCI): A technology that allows direct communication between the brain and a computer system, enabling users to control VR environments using brain signals.

Cognitive Load: The amount of mental effort required to process information during a task, which can be influenced by the complexity of VR environments and needs to be managed in UI/UX design.

Graded Exposure: A method in exposure therapy where the intensity of exposure to anxiety-inducing stimuli is gradually increased, allowing patients to build resilience in a controlled manner.

Weak Central Coherence (WCC): A theory in autism research suggesting that individuals with autism focus more on local details than on global processing, which can affect how they interact with VR environments.

Serious Games: Games designed with a primary purpose other than entertainment, often used in VR for educational or therapeutic purposes, such as building social skills or reducing anxiety.

Universal Design (UD): A design philosophy focused on creating products and environments that are accessible and usable by as many people as possible, essential for making VR inclusive.

Animacy Perception: The cognitive ability to attribute life-like qualities or intentions to moving objects, studied in VR to understand how humans perceive social and biological movements.

Visual Search: A cognitive process where individuals search for a target object within a cluttered environment, often studied in VR to analyze attention, memory, and spatial navigation skills.

Prolonged Exposure Therapy: A type of exposure therapy commonly used to treat PTSD, where individuals repeatedly relive their traumatic experiences in a controlled setting to reduce their emotional response.

Decentring: A mindfulness-related skill where individuals learn to observe their thoughts and emotions from a detached perspective, reducing emotional reactivity, often enhanced by VR mindfulness practices.
