Documentation surrounding a recent Apple patent published by the United States Trademark and Patent Office reveals that the iPhone-maker is working on a new intelligent multi-tiered haptics system. The Cupertino-based company states that traditional tactile feedback systems
provide a user with the ability to interact with a device through touch or contact. Using the technology described in the patent documentation, Apple’s invention could allow a future iPhone’s display to deform into a button, an arrow, or even a geological map with 3D depth, according to PatentlyApple
. The system would adopt a tiered haptic response approach, in which one or more arrays of shape-changing elements would provide tactile interaction through an elastic screen interface.
