In the recent version of iOS, Apple has provided an application called GarageBand, which contains such a function through which the strength of pressing a key on a virtual keyboard can be lowered or increased, with respect to the pressure the user applies on it.
Apple Insider reports that though the present process is involved with the advanced accelerometers, a new patent application, unveiled by the US Patent and Trademark Office, states that the touch velocity can also be estimated by applying gyroscope, microphone, Hall Effect Sensor, compass, ambient light sensor, proximity sensor, camera, or a positioning system.
The recently revealed patent, known as “System and Method for Enhancing Touch Input”, explains a method of measuring the touch input velocity. The iOS device sensors help the system to estimate the velocity, even if the screen is not sensitive to the pressure.
Apple states that the velocity sensed by an integrated accelerometer alone has a less accuracy percentage as the calculation is done through only z axis. The accuracy can be increased significantly if more sensors are being used.
By applying new methods, Apple is expected to enhance the accuracy of estimating velocity to a great extent.
