Have you ever assumed that an ordinary PC mouse
"has a fixed shape"?
Symmetrical left and right, with edges,
a click here, a scroll wheel there.
Melt Mouse is a PC mouse that dissolves that very premise.
And not just the mouse itself.
Pointer control, gestures, and numeric keypad input — all three functions
melt together into a single device.

| What is Melt Mouse?

Melt Mouse is
an integrated input device that combines
the conventional mouse, trackpad, and numeric keypad into one.
- Clicks and movement, like a mouse
- Gesture control, like a trackpad
- Number input and shortcuts, like a numeric keypad
Every function is designed
to switch the moment you place your fingers on it.
This flowing operating experience
sets it apart from a mere multifunction mouse.

Melt Mouse's defining feature
lies in its very design philosophy of "melting boundaries."
Having a separate pad and mouse,
or a separate numeric keypad,
has always created "hand movements" and "perceptual breaks."
Melt Mouse
eliminates those "boundaries" right at the entry point of the mechanism itself.
- Where you touch
- The pressure of your finger
- The motion of a gesture
All of these are designed
to be completed entirely through finger movement.
This isn't simply feature integration —
it's a philosophy of optimizing the natural flow of the hand itself.

Melt Mouse has no physical buttons.
The click sensation is entirely reproduced through haptics (tactile feedback).
As a result,
- No clicky clacking sound
- Less impact on your wrist and fingertips
- Scrolling and input become a "flowing operation"
You experience a kind of quiet precision.
In numeric keypad mode,
an LED indicator visually shows you the current input mode.
This isn't mere decoration — it's a UI that ensures usability without you having to think about it.

Melt Mouse is different
from the old-school mouse that "only moves a pointer."
To get the most out of it, you also need to design how you use it.
① Speed up your work with gestures
Just like a trackpad,
switching between one-, two-, and three-finger gestures
makes window switching, page scrolling, and app switching feel intuitive.
② Assign shortcuts to the numeric keypad
The numeric keypad isn't just for typing numbers —
you can also assign it as shortcut keys.
Whether for photo editing, spreadsheets, or programming,
it offers a way to boost your work efficiency.
③ Customize the haptic feel
The strength of the click sensation
and the notch feel of scrolling
can be freely adjusted in the dedicated app "Melt Studio."
This isn't just a "preference setting" —
it's the very design of an operating feel that fits your body.
Who it's for
Melt Mouse
isn't just a high-spec gadget.
It's a tool that redesigns the quality of operation and experience.
It's especially suited for:
- People who want a consistent flow across diverse operations
- People who have found switching between mouse and numeric keypad cumbersome
- People who want to feel the operation through touch rather than physical buttons
- People who want to reduce hand fatigue during long work sessions
It resonates with people
who value the experiential quality of operation itself, not just performance.

What did you think?
Melt Mouse
isn't just a mouse with a different shape.
Pointer control, gestures, numeric keypad input —
it's a tool that connects layers that were originally separate, right at your fingertips.
The idea of "erasing boundaries"
isn't merely about merging features.
Making the interface between body and screen boundary-less
— that is the true value of Melt Mouse.
