The future of text input might not involve physical keyboards at all. Microsoft recently filed a patent titled “Holographic Keyboard Display,†offering a glimpse into how we might type in the future. This AR/VR technology allows users to interact with a virtual keyboard plane, detecting gestures as if they were typing on a real keyboard. The holographic keyboard would function just like a traditional one, but without the need for physical hardware.
This concept is first mentioned in the context of gaming, but Microsoft’s broader interest in corporate IT suggests that the workplace could be another major application. With advanced AR/VR headsets, knowledge workers may no longer need a physical desk or even a centralized office. Instead, smartphones could simulate desktop PCs, enabling employees to type using hand gestures from anywhere, anytime.
The patent also introduces an "HMD (Head-Mounted Display)" device, which helps track user movements and supports both virtual reality and mixed reality applications. This innovation opens up new possibilities for immersive computing experiences.
Looking at the images included in the patent, it shows an AR/VR environment featuring a Kinect sensor, a TV, a floating virtual keyboard, and an augmented reality guide. The holographic hands represent the user’s real hands resting on the virtual keyboard, allowing for seamless typing from any position.
The system uses head tracking to fix the holographic keyboard in space, ensuring that the interface remains visible regardless of the user's head orientation. This makes the experience more intuitive and user-friendly.
While the patent highlights game applications, such as an interactive game with a holographic guide, the potential extends beyond entertainment. Virtual keyboards could eventually replace traditional work setups, especially with Microsoft’s strong presence in productivity tools like Office. The company has already shown interest in expanding AR use cases, including smart glasses that can recognize food and dining environments.
Microsoft has been making moves in the AR space through HoloLens, which was partly developed from technology acquired from ODG, a smart glasses manufacturer. With ongoing advancements, it's easy to imagine future versions of HoloLens coming equipped with an AR-enabled word processor, similar to Microsoft Word on a PC.
As this technology evolves, the way we interact with digital devices will change dramatically, making text input more natural and accessible than ever before.
Matte Films
A good day usually starts when the sun rises, and bright light can improve our vision. The only exception is that due to excessive exposure to the sun, the screen will almost become insufficient due to reflections.
In order to solve the problem that you can enjoy the sun and read the phone screen at the same time, please install an Anti-glare Matte Screen Protector on the screen. Since the surface of the Screen Protective Film is matte, it has an anti-glare effect, and you can see the screen clearly without feeling dizzy.
The Frosted Screen Protector also allows you to sit on the beach during the holidays, or sunbathe on the balcony with your mobile phone or laptop at home, check emails, read or watch movies. Thanks to the Matt Screen Protector and its anti-glare function for laptops, smartphones, etc., electronic devices can be used even in bright sunlight.
In addition, the Matte Protective Film uses an oleophobic and waterproof coating to eliminate grease and dirt, thereby greatly reducing the formation of greasy fingerprints on the display. Please maintain a clear vision when exposed to the sun.
