click
the mouse of the future
problem
a
with augmented reality gaining in potential widespread adoption, there will be a need for a device that serves the purpose of offering a mechanism to establish click-intent. the question of how one will seamlessly click something in augmented reality is not yet ironed out in a manner that can effectively scale for mass-market implementation.
b
in the relatively near future, we may have increased access to graphic-user-interfaces, in which case there will be a need for a device that allows for the manipulation of these interfaces at scale.
solution
idea
a bluetooth-enabled universal mouse that allows a person to manipulate any graphic user interface, both augmented and real.
device characteristics
click is a ring meant for the pointer finger on a human hand that has (1) a clickable portion, (2) a touch-sensitive area (for scrolling), (3) a fiber-optic gyroscope, (4) a lithium-ion battery, and (5) an antenna with bluetooth compatibility. the user interacts with the ring with their thumb.
features
-
double-tap & hold while pointing at a graphic-user-interface to 'ask to join the device'
-
adjustable in size to fit any finger
-
can measure orientation of hand to determine either 2-dimensional movement of a cursor on a flat graphic-user-interface or 3-dimensional movement of a cursor in an augmented reality interface.
fiber-optic gyroscope
a fibre-optic gyroscope senses changes in orientation using the sagnac effect, thus performing the function of a mechanical gyroscope. However, its principle of operation is instead based on the interference of light which has passed through a coil of optical fibre, which can be as long as 5 km.
two beams from a laser are injected into the same fibre but in opposite directions. Due to the sagnac effect, the beam travelling against the rotation experiences a slightly shorter path delay than the other beam. The resulting differential phase shift is measured through interferometry, thus translating one component of the angular velocity into a shift of the interference pattern which is measured photometrically.
