Researchers at Carnegie Mellon University have made a groundbreaking development in smartphone displays by creating a technology that incorporates physical keys into flat screens. Unlike the traditional on-screen keyboards that rely on haptic feedback, this new technology uses embedded electroosmotic pumps to generate actual bumps on the display.
The thin panel, placed behind the OLED screen, contains miniaturized hydraulic pumps that can create tactile bumps and form a physical keyboard when required. Each pump is individually controlled, allowing for various functions and providing users with a more immersive and realistic typing experience.
The innovative technology keeps the size of the bumps discreet, with tests indicating dimensions of 2mm. Carnegie Mellon University currently owns the technology and may consider licensing it to smartphone and notebook manufacturers for future product integration. This development has the potential to reshape how we interact with our devices and improve typing speed and productivity on smartphone displays.
Looking ahead, this technology opens up possibilities for dual-screen notebooks that can transform the lower end into a physical keyboard. Users would have the flexibility to switch between a dual-screen experience and a traditional keyboard setup, enhancing productivity in different scenarios. While commercial use of this technology may still be a few years away, the demonstration video showcases its potential and piques excitement for future advancements.
For further details, the researchers have published a PDF with detailed information about their work. Additionally, a video demonstration is available, offering a visual insight into the capabilities of this innovative technology. Share your thoughts and opinions on this remarkable development as we imagine a future where tactile feedback on flat smartphone displays becomes the new standard.
