Apple’s Solid-state Button Patent
Apple’s latest patent for a solid-state button technology has the tech community buzzing. According to well-known analyst Ming-Chi Kuo, the iPhone 15 Pro models will use this technology, which eliminates physical buttons and replaces them with simulated tactile feedback provided by the Taptic Engine linear motor.
Apple’s solid-state button patent summary states that there is a need for electronic devices with improved button methods beyond mechanical and solid-state that will provide interfaces, haptics, and/or audio feedback during interaction with an off-display input region, making manipulation of user interfaces more efficient and intuitive for a user.
Apple’s new solid-state button technology will bring more features than just simulated tactile feedback. According to the patent, the iPhone 15 Pro‘s power button and volume keys both support pressure sensing, with a different force matching different operations and functions.
For example, a light press will slowly increase the volume, and a stronger force will quickly increase the volume, making it easier for users to quickly adjust. The power button can also be used to open more function options with different strengths, acting as an extra shortcut button.
These initiatives by Apple are designed to let users get used to the prelude to a full-touch world in advance. As users become more accustomed to linear motor feedback, physical buttons may become less necessary. This technology is yet another example of Apple’s commitment to innovation and pushing the boundaries of technology.
