Apple Patents a Force Imaging Input and Device System
Posted on Oct 5, 07 09:41 AM PDT
Apple wants to go beyond the binary touch that equips most touch screen today by not only detecting “if” the screen was touched, but also which “how much force” they were touched, opening the doors to future potential user interface improvement. It works by having a few extra layers, one of which can bend and tell how much pressure was applied to the surface. Something similar might be used in graphics tablet, but I never destroyed one to verify. If someone knows, please post a comment.
