What is mixed reality?

Immersive technologies include virtual reality, augmented reality, and mixed reality

Virtual reality relies on technologies that use screens to generate every pixel, immersing a user in an entirely digital world. In contrast, augmented reality overlays digital content onto views of the real world. Mixed reality combines both to allow real-time interaction with virtual objects.

Virtual and augmented realities are paving the way for a more immersive future

Tech companies like Apple, Meta, and Microsoft invest heavily in immersive technologies such as virtual, augmented, and mixed reality. While VR transports users to a fully digital space and AR adds digital elements to the real world, mixed reality allows interaction with both at once.

Integrating mixed reality has made art galleries and museums more interactive and accessible

Schizophrenia literally means 'split mind'—a reference to patients' break with reality

Contrary to the name, patients do not have multiple personalities. Rather, the split mind refers to the sufferers' inability to distinguish reality from hallucinations when they are aware and awake. Cognitive difficulties, including challenges focusing and communicating are also common among those with schizophrenia, as well as auditory and visual hallucinations.

Mental health is much more than the absence of mental illness

It's a state of well-being that allows individuals to cope with daily stressors, realize their abilities, learn and work effectively, and contribute to their overall community. Inextricably linked to physical health, modern science indicates that mental health is a central component of our overarching ability to function and enjoy life.

Vertigo is a mismatch of information between the eyes and the ears

Both vertigo and motion sickness can be caused by mismatches between visual and auditory inputs.The brain relies on inputs from the eyes, inner ear, and receptors in muscles and joints to orient the body. When the eyes suggest movement but other signals suggest the body is stationary dizziness and nausea can occur.
