Apple continues to work on Finger Accessories that allows a user to make 3D Air Gestures to control content playing in a VR Headset
In 2019 Patently Apple posted a patent application report titled "New Apple Patent reveals Finger Devices to be used with a Future Mixed Reality Headset instead of Sensor Gloves." The patent revealed that Apple was working towards a future headset that could use slip-on finger sensor devices that would provide accurate hand feedback allowing users to work with content seen on the display of a headset
using three-dimensional air gestures and more.
Apple's patent FIG. 26 below illustrates a side view of an illustrative finger-mounted device being worn on a finger at a location other than the tip of the finger; FIG. 27 is a side view of an illustrative finger-mounted device with optical sensors for gathering touch input from the upper surface of a user's finger; and FIG. 28 is a diagram showing how markers may be used in calibrating a system in which a finger-mounted device is used.
