Mokibo, Inc., develops a human interface device for rapidly changing IT devices. We conducts research on human interface devices which will be integrated with upcoming top-notch technologies ranging from mobile devices, laptops, and tablet PCs to AR and VR. We invented and introduced the Fusion keyboard to the world for the first time. Fusion keyboard has the function of turning the entire surface of the keyboard itself into a touchpad. Though the product is similar in size to normal keyboards, the touchpad is twice as big as preexisting touchpads. Thus, the product has excellent mouse control despite its small size. This reduces the probability of "mouse arm" and reduces the time required to switch between the keyboard and mouse because this requires only finger movement. Furthermore, the user may switch the device to control easily as the device can be simultaneously connected to up to three devices. ★ The Full-sized Pantograph Keyboard with a World Largest Touchpad. ★ Muli-OS support. Windows, Android, macOS, iOS, and iPadOS. ★ Pair up to 3 Bluetooth devices at the same time. ★ Extremely Portable. Ultra-thin and ultralight. ★ Rechargeable Battery.
