Future Smartphones Are Expected To Come Without Buttons, Use Ultrasonic Touch Technology
With every innovation brought by mobile manufacturers, the expectations of customers are soaring high. To satiate these ever-growing demands, mobile manufacturers are always in tough competition against each other, while being dedicated to bringing the best features and handy specs in their latest smartphones. While some focus on enhancing extraordinary camera quality, others concentrate on bringing a new look to the phone. For an edge-to-edge experience, the manufacturers strive hard to provide exceptional design in a minimalist manner. This scenario is the result of new and emerging technologies that end up as virtual buttons.
Sentons, a startup in the USA has recently confirmed that the company, in collaboration with two smartphone makers and under an existing contract with Asus Computer Inc., has revolutionized a technology that will put an end to gadget buttons.
Led by Jess Lee, an engineer who sold his previous company to Apple Inc, Sentons announced a sensor system that uses ultrasonic sound waves to detect touches, presses, and swipes on various materials like metal edges around a smartphone.
Commenting on this innovation, Lee has informed media outlets, “Touch screens are great, but (phone makers) hadn’t been able to figure out how to add interactivity to the sides. With the thinner and thinner form factors, perhaps even all-glass or with funky metallic edges that are thin, there’s no space for buttons.”
An absolute button-less smartphone is a piece of thrilling news for the customers but a troublesome work for the makers. So, the question lies is how will Sentons make this happen? It is a magic of a custom chip that sends out the sound waves and contains a processor and algorithms for understanding various gestures.
California-based Sentons is also engaged in allowing users to scroll through apps on phones for one-hand usage. Another important feature that the technology wing of the company is working on is a virtual shutter button that is entirely dedicated to working on the camera of the phone in a similar manner a physical shutter button works on dedicated digital cameras.
Lee has also enlightened readers about the company’s dream to add touch interactions to devices where screen space is either extremely restricted like the frames of smart glasses or the bands of smartwatches, or where there are no screens at all, like the steering wheels of cars.
