• Machine Learning (ML): Leverages data to recognize patterns and make predictions without being explicitly programmed to do so.

🩺 PULSE CHECK

📜THE PRELUDE

As you step onto the cliffside cable strung between jagged peaks, a piercing breeze chills your calves, tingling every nerve with alertness. Your heart races from the raw thrill of balancing on a thread suspended above the frosted abyss.

At the tightrope’s midpoint, a frigid gust sweeps across your body, tightening your stomach and sending shivers of adrenaline up your spine. You pause, steady yourself, and press forward, eyes locked on the opposite cliff.

Suddenly, without warning, the snowy mountains vanish, along with the bridge, the cable’s creaks, and the scent of pine. You slide the VR Headset upward and hand it back to the immersive experience engineer.

You’re at the University of Tokyo’s Information Somatics Lab, and just participated in a fully immersive VR Simulation designed to replicate bodily sensations like touch, torque, tension, tingling, and temperature.

Although full-body immersion technology may still be experimental, it’s inching closer to consumers. Soon, we’ll be able to simulate lifelike experiences within digital environments by engaging our five main senses: sight (i.e., eyes), sound (i.e., ears), smell (i.e., nose), taste (i.e., tongue), and touch (i.e., skin).

As the boundary between simulation and reality continues to blur, we’re forced to ask: “What happens when a virtual world becomes compelling enough to tempt us away from our own?”

🔮WHAT COULD VR BECOME?

⦿ 1️⃣ The Experience Machine?

In 1974, American philosopher Robert Nozick proposed the following: Imagine a futuristic device exists called The Experience Machine that can simulate your perfect life. You simply tell it exactly what brings you the most happiness, including every success, every pleasure, and every thrill.

On the surface, this futuristic device might seem irresistible. Who wouldn’t want to live in a simulated reality tailored to their deepest desires, right?! Despite this, Nozick argued that most people would hesitate, or even refuse, to use The Experience Machine because pleasure alone isn’t enough to fulfill us. Without failures, success doesn’t taste as sweet. We don’t just want desirable experiences. We want empowering experiences that challenge us to grow.

This thought experiment confronts a deeper truth: “Do we value happiness above all else, or do we value becoming someone through the struggles, triumphs, and unpredictability of everyday life?”

⦿ 2️⃣ Is VR an Experience Machine?

Today’s VR is nothing like The Experience Machine. When you put on the Headset, you’re teleported into a virtual world where your aim might be off, or you might not unlock the next level. All these experiences involve struggle and the possibility of losing, forcing you to improve. Eventually, you can succeed. That’s exactly the appeal. Many virtual worlds simulate consequences to reinforce the sense that choices directly affect future outcomes.

But even with simulated consequences, VR still offers something Nozick may have been skeptical of: an escape from the rawness of ordinary life. It enables you to step into a virtual world where feedback is immediate, the path to success is clear, and the fallout of failure vanishes when you take off the Headset. Ultimately, whether you can truly “escape” reality depends on the quality of full-body immersion technology. So, what’s possible today?

📈WHAT CAN VR DO?

⦿ 3️⃣ The Four Pillars of Immersion?

Imagine you slip on a Meta Quest 3 Headset and load The Climb 2, where you must traverse towering skyscrapers and jagged mountains. To convince your brain the virtual world feels real, four mechanisms work in perfect harmony:

1. Optical Fidelity:

   • Mechanism: ML algorithms track eye movements to predict where you’ll look next, enabling Headsets to render high-resolution details within your focus. This perceptual effect allows the virtual world to update your viewpoint in real time to keep the simulated reality stable as you move.

   • Effect: As you peer over the edge, pedestrians look like crawling ants.

2. Spatial Audio:

   • Mechanism: ML models examine the virtual world’s 3D layout to map out the source of each simulated sound’s position relative to the Headset’s movements. In other words, as you turn your head, the Headset constantly recalculates how sound waves reach your ears, adjusting delay, reverb, and volume.

   • Effect: Every door closing, rock falling, or siren sounding contributes to your spatial awareness.

3. Hand Tracking:

   • Mechanism: Four tiny cameras constantly capture snapshots of your physical surroundings. Five tiny motion sensors measure the rotation and acceleration of your hands and head. Then, a technique called VI-SLAM combines these signals to build a 3D map of your surroundings. As you move, it constantly renders the exact position of your hands and head relative to the simulated reality.

   • Effect: Every lean, peak, and reach feels natural.

4. Basic Touch:

   • Mechanism: When you grasp the railing, the Meta Quest Touch Plus Controllers deliver a subtle vibration through Haptic Actuators: tiny motors that create micro-vibrations to mimic real handling. As you pull upward, it tracks your body’s position through Inverse Kinematics, mapping the motion of how your virtual wrist, elbow, and shoulder should bend within the virtual world to mirror your actual hand movements.

   • Effect: Every grip, pull, and tug stimulates your palms and fingertips.

📉WHAT CAN’T VR DO?

⦿ 4️⃣ Touching the Virtual?

Simulations already convince your eyes and ears that you’re somewhere else. However, full sensory immersion still remains out of reach. More specifically, your movements and the exact sensations of those movements still feel muted.

1. High-Fidelity Touch:

   • Example: Although grabbing a rocky handhold triggers a buzz throughout your Meta Quest Touch Plus Controllers, you don’t truly feel every ridge, crevice, and groove of the rock.

   • Recent Research: HaptX Gloves G1 mimic touch by using Microfluidic Actuators: 133 air-filled bladders, each the size of a grain of sand, placed across your palm and fingertips.

   • Projected Timeline: Expected to reach consumers within the next 10 years.

2. Full-Body Sensation:

   • Example: When wind gusts, you can see debris swirl, but the wind’s force doesn’t pin you to the railing.

   • Recent Research: The Teslasuit is covered in Electrical Muscle Stimulations (EMS) that send rhythmic contractions throughout specific muscle groups to simulate recoil, tension, and impact. Thermoelectric Patches heat or cool specific body regions to replicate temperature fluctuations.

   • Projected Timeline: Expected to reach consumers within the next 15 years.

🔑KEY TAKEAWAY

As high-fidelity touch and full-body sensation come online, virtual worlds will offer a true escape from reality by delivering pleasure with almost no effort. We must strive to make our lives compelling enough so that any temptation to escape becomes irrelevant.
