The present disclosure relates to techniques for managing navigation alerts. The disclosure generally describes an exemplary technique whereby a first device, such as a smartphone, coordinates the timing or sequence of alerts for a navigation instruction on the first device and on a second device, such as a smartwatch. In some examples, the second device presents an alert to a user indicating an event condition has been met before the first device presents a different alert to the user indicating that the same event condition has been met. The alert presented on the second device and the different alert presented on the first device are spaced apart in time by at least a predetermined delay time period, where the predetermined delay time period is based on the event condition. The alert at the second device allows the user to anticipate the alert at the first device.

The present disclosure concerns a method and apparatus for the creation of an acoustic field for providing tactile sensations. More particularly, but not exclusively, this disclosure concerns a method and apparatus for the creation of an acoustic field providing tactile sensations for use with an interactive device.

The disclosure provides a method of generating a tactile sensation. The method comprises the steps of providing a plurality of acoustic transducers arranged to generate a predetermined distribution of pressure patterns, wherein the pressure patterns comprise a first region providing a first tactile sensation and a second region providing a second, different, tactile sensation.

One aspect of the technology involves a system for measuring the rotational position of a rotating shaft, including a field source configured to generate a measurable field, a sensor configured to measure the generated field, and a target that is configured to modify the generated field as measured by the sensor to have a shape with (a) at least one measurable feature for a zero reference point, and (b) a shape that varies throughout one or more angles such that a rotational position of the shaft is determined with a selected angular accuracy. There is also a device that receives a query for the rotational position of the shaft a device that responds to the query. Another aspect involves generating multi-frequency vibrations with a single linear resonant actuator (LRA). This LRA can exhibit a beat pattern in response to being driven by the sum of two different sinusoidal functions.
