🖐 Imagine pinching an object on your screen and instantly feeling its stickiness or softness — without wearing a glove, holding a controller, or touching anything at all. That experience may soon be possible with nothing more than a smartphone camera.

NTT's "world-first" illusion technology, announced on May 12, 2026, challenges the conventional wisdom of haptics — which has long relied on vibration motors, exoskeleton gloves, and other physical devices. This article explores what the new technology actually does, how mainstream haptics works today, and what problems this "touchless touch" approach could solve.

What Makes This a "World First"

On May 12, 2026, Nippon Telegraph and Telephone Corporation (NTT) announced that it has developed the world's first technique to convey the textures of "softness" and "stickiness" in an augmented reality (AR) environment without any physical contact. Part of the research has been published in IEEE Transactions on Visualization and Computer Graphics, a leading international journal in the haptics field, and a demo will be shown at NTT Communication Science Laboratories' "Open House 2026" starting May 20.

The key feature: users wear nothing, touch nothing, and yet experience material qualities just by moving their fingers in front of a PC or smartphone screen.

The mechanism is elegantly simple. A camera tracks the user's hand movements in real time, and a virtual object displayed on the screen deforms in sync — squishing when the user pinches, stretching when the user pulls apart. The brain processes this match between "my own hand motion" and "the on-screen deformation" and generates the illusion of touch from visual information alone.

Two Parameters That Create the Illusion

What NTT's researchers established experimentally is the precise relationship between what kind of visual deformation produces what kind of texture sensation.

Softness is determined by "spatial deformation range"

When pressing a virtual object, how widely the deformation spreads across its surface determines the perceived softness. With 130 experimental participants evaluating videos with varied push depths and deformation ranges, the team found that the object feels softest when the deformation spread is around 16–32 pixels.

Stickiness is determined by "stretch distance until break"

When pulling a virtual object apart with two fingers, the distance it stretches before "breaking" determines the perceived stickiness. The longer it stretches, the stickier it feels — like mochi at the extreme, like oil at the short end. This was confirmed consistently in both a 31-person laboratory study and a 57-person online study conducted via smartphones.

In other words, by controlling pixel-level deformation parameters, the system can plant in the viewer's brain the impression "this is a soft gel" or "this is a sticky candy."

What "Mainstream Haptics" Looks Like Today

To understand why NTT's approach is significant, it helps to map the mainstream haptics landscape it sits against.

Current haptic technology splits into two broad families.

① Tactile feedback (stimulating the skin surface)

  • Vibrotactile: The dominant method. Phone notification vibrations, game controller rumble, the nuanced feedback of the PS5 DualSense — all use eccentric rotating mass (ERM) motors, linear resonant actuators (LRA), or piezoelectric elements. Cheap and easy to implement, but limited to "variations of vibration."
  • Ultrasonic mid-air haptics: Arrays of ultrasonic transducers focus acoustic pressure onto an unworn hand, creating sensations of texture in midair. NTT itself announced a "smooth/rough mid-air ultrasonic haptics" technology in May 2025. No wearable required, but the system needs hundreds of transducers in a dedicated array.
  • Electrotactile: Weak electrical currents directly stimulate tactile nerves in the skin — used in braille displays and some experimental interfaces.

② Kinesthetic / force feedback (applying force to muscles and tendons)

  • Exoskeleton devices: Mechanical frames worn on the hand or arm use motors to resist finger movement. Diver-X's recently acquired "EXOS" system, HaptX gloves, and similar products belong here. They can reproduce real "resistance" — the firmness of a virtual object, the weight of a virtual hammer — but the hardware is heavy, expensive, and impractical for daily home use.
  • PS5 adaptive triggers: The DualSense controller's variable-resistance triggers simulate the tension of drawing a bowstring or compressing a spring — currently the most sophisticated consumer-grade force feedback.

What these mainstream approaches all share: some physical device either touches the user's body or generates a physical stimulus. Touch is delivered to the brain through some kind of physical intermediary.

NTT's Work Sits in the "Pseudo-Haptics" Lineage

NTT's new technology belongs academically to a field called pseudo-haptics, a concept systematized around the year 2000 by French researcher Anatole Lécuyer and colleagues. The core idea: exploit the mismatch between visual feedback and the user's motor actions to create tactile illusions without any physical stimulus.

Familiar examples include slowing down a mouse cursor to create the illusion of "heaviness," or showing a user's hand in a slightly different position in VR to make them feel their hand is being pushed.

NTT has been accumulating research in this area for years:

  • 2021: Applied the "velvet hand illusion" to develop a method where rotating a thin perforated sheet between the hand and any object makes rough surfaces feel softer and smoother.
  • March 2025: Discovered that changing the spacing of stimulation points on the skin alters perceived motion speed.
  • May 2025: Showed that rotating an ultrasonic focal point at 5 Hz amplifies perceived force roughly 20-fold (still uses physical stimulus, but no wearable).
  • May 2026 (current): Established a method using purely visual information to convey texture.

This latest announcement marks an extreme: not "make the device lighter" or "make the device smaller," but "eliminate the device entirely." A smartphone's front camera and display are sufficient.

What Problems Could This Solve?

NTT lists four application domains: e-commerce, remote communication, education/training, and entertainment. Each addresses a concrete real-world problem.

① The "can't touch online" problem in e-commerce

The biggest source of anxiety in online shopping for clothes and food is that you can't gauge the texture of the actual item. Is the T-shirt scratchy or soft? Is the bread fluffy or dense? Photos and descriptions can't fully resolve this — and the resulting return rates directly cut into e-commerce margins. In apparel specifically, return rates can reach 20–30%.

Past research has explored "vibration gloves that simulate fabric texture," but requiring consumers to wear hardware is impractical. NTT's method needs only a camera-equipped phone — the user just "pinches the sweater on the screen" to get an intuitive sense of its softness. The bar for retailer adoption is correspondingly low.

② Sharing textures in remote communication

Saying "this is really chewy" over a video call doesn't really convey what you mean. With this technology, the listener could potentially "feel" the same texture by interacting with their own phone screen. Use cases include cooking instructors conveying dough firmness to remote students, or medical professionals sharing impressions of a patient's tissue with a remote consultant.

③ Substituting for the real thing in education and training

For materials students can't easily touch — human tissue, hazardous substances, rare crafts — pseudo-haptics offers a way to experience their qualities. Cooking and pottery classes could give remote participants a tactile sense of how dough or clay should feel at each stage.

④ Accessibility and the cost barrier

A point easy to overlook: this technology is fundamentally cheap and universally available. EXOS-style exoskeleton devices run hundreds of thousands of yen per unit, bHaptics vests cost $300–$500, and HaptX gloves are essentially out of reach for individual buyers. Pseudo-haptics requires only a smartphone — a vastly different reach in emerging markets and for individual consumers.

The Limits That Remain

That said, pseudo-haptics doesn't replace mainstream technology in every domain.

Because no actual physical stimulus is delivered, the strength of the "touching" sensation can't match the real thing. For applications that need strong, real-time force feedback — the heft of a sword swing in a VR game, the tissue resistance felt by a surgeon manipulating a scalpel — force feedback hardware remains necessary.

The illusion also depends on tight synchronization between screen and finger motion, which makes it vulnerable to communication latency. If two users share textures remotely and the lag exceeds a few dozen milliseconds, the illusion can break down. NTT itself lists latency and device variation as key verification topics going forward.

The right framing isn't "haptics has a new king." It's that this technology opens a new layer — bringing texture experiences cheaply to an enormous market (ordinary smartphone users) that previously had no access to haptic feedback at all.

What "Touchless Touch" Could Change About Consumption

Online shopping has pushed Japan's e-commerce market past 20 trillion yen (roughly $130 billion) annually. Consumers are now used to buying by "looking and reading." But in categories where "you really want to touch first" — clothing, food — physical stores still hold strong advantages.

If NTT's illusion technology reaches practical deployment, actions like "pinching a sweater on screen to check its softness" or "stretching a virtual mochi to test its stickiness" could become routine. That's not just a convenient feature — it's an attempt to extend the human sense of touch itself into digital space.

NTT says it will investigate applying the framework to other texture qualities like weight and temperature. If a systematic, vision-based texture presentation technology takes shape, it could simultaneously address the e-commerce return problem, sensory sharing in remote medicine and education, and immersion in the metaverse — all from a single foundation.

How Is It in Your Country?

In Japan, instead of strapping on a vibration glove to solve the "can't touch online" problem, researchers came up with the idea of "tricking the brain via screen and finger movement." In your country, do you feel frustrated by not being able to gauge texture when shopping online? When you buy clothes or food online, what do you rely on to make decisions? And how do you feel about the spread of these "illusion technologies" — exciting, or unsettling? Let us know in the comments.
