What is reality and how do we know? For many the answer is simple: What you see — hear, feel, touch, and taste — is what you get.

Your skin feels warm on a summer day because the sun exists. That apple you just tasted sweet and that left juices on your fingers, it must have existed. Our senses tell us that reality is there, and we use reason to fill in the blanks — that is, we know the sun doesn’t cease to exist at night even if we can’t see it.

But cognitive psychologist Donald Hoffman says we’re misunderstanding our relationship with objective reality. In fact, he argues that evolution has cloaked us in a perceptional virtual reality. For our own good.

A glove focused on user experience in interacting with virtual objects is in the news. This virtual reality glove is the topic of a research article. The researchers described their virtual reality glove in detail in their paper, “Pneumatic actuator and flexible piezoelectric sensor for soft virtual reality glove system,” in Scientific Reports.

No, this is hardly the first instance of researchers able to reproduce texture but this attempt is noteworthy. As pointed out in natureasia.com, the glove system in this instance is one that allows the wearer to manipulate a virtual hand, pick up an object in virtual reality and feel its shape.

Bill Andrews took to the D-brief blog on Discover to examine the glove’s characteristics— of and actuators. The Korean team designed it as a glove to manipulate a virtual hand inside a digital realm, said Andrews.

Though it may not have the sting of death and taxes, presbyopia is another of life’s guarantees. This vision defect plagues most of us starting about age 45, as the lenses in our eyes lose the elasticity needed to focus on nearby objects. For some people reading glasses suffice to overcome the difficulty, but for many people the only fix, short of surgery, is to wear progressive lenses.

“More than a billion people have presbyopia and we’ve created a pair of autofocal lenses that might one day correct their vision far more effectively than traditional glasses,” said Stanford electrical engineer Gordon Wetzstein. For now, the prototype looks like virtual reality goggles but the team hopes to streamline later versions.

Wetzstein’s prototype glasses—dubbed autofocals—are intended to solve the main problem with today’s progressive lenses: These traditional glasses require the wearer to align their head to focus properly. Imagine driving a car and looking in a side mirror to change lanes. With progressive lenses, there’s little or no peripheral focus. The driver must switch from looking at the road ahead through the top of the glasses, then turn almost 90 degrees to see the nearby mirror through the lower part of the lens.

Where reality is still lagging considerably is in recreating the physical experience of VR. In the movie, the haptic gloves OASIS players wear make them virtual objects almost indistinguishable from real ones. Other characters have even more advanced set-ups, like full-body haptic suits that simulate both pleasure and pain, complicated harnesses and treadmills that allow users to run around and move their bodies just like they would in real life, and even “smell towers.”

But a report released by analysts IDTechX to coincide with the movie’s release suggests the first step towards most of these technologies has already been taken. VR handsets already feature the same kind of rumble packs found in computer game controllers that provide simple haptic feedback in the form of vibrations.

These same vibration motors have also been integrated into VR gloves like Gloveone and Manus, where they can recreate textures. Go Touch VR’s haptic rings use a small motor to vary the pressure of a piece of plastic against your fingertips to mimic the force felt when touching objects, while Ultrahaptics beams ultrasound onto your hands to give the sensation of pressure and texture.
