Definitions

  • a shuttle includes means to determine information relating to the throw or state of motion of the shuttle, and means to convey an audio information signal to a user during the throw.
  • throwable objects such as shuttles, football and vortex footballs. More recently, such throwable objects have incorporated on-board electronics to measure and display information such as the distance travelled by the ball, for example using an accelerometer in combination with a microprocessor as disclosed by US 5,779,576.
  • US 2008/0234077 discloses a ball comprising a motion switch that emits a sound at different intervals when passed from player to player to indicate to the players a stage of the game, e.g. when playing "hot potato".
  • an accelerometer is not able to distinguish between motion of a ball in the hand and motion of a ball through the air. When a swing is given to a ball by a player before it is thrown, the accelerometer will generate travel information assuming that it is already in mid-air, which pollutes the true distance measurement data.
  • a throwable object comprising a body, the body housing: a throw sensor comprising at least one of an inertial measurement unit (IMU) and a barometric pressure sensor, the throw sensor arranged to periodically measure travel data describing the motion of the object during a throw, wherein the travel data relates to one or more of the object's position, speed, height, acceleration, velocity, angular rate, roll, pitch, or yaw; a processor arranged to receive travel data measurements from the throw sensor and to determine, during the throw, whether a recent travel data measurement is different to a previous travel data measurement; and a speaker arranged to emit a sound when the processor determines a difference.
  • IMU inertial measurement unit
  • barometric pressure sensor the throw sensor arranged to periodically measure travel data describing the motion of the object during a throw, wherein the travel data relates to one or more of the object's position, speed, height, acceleration, velocity, angular rate, roll, pitch, or yaw
  • a processor arranged to receive travel
  • such a throwable object provides for improved feedback to a user, for example when playing a throwing game with the object, because a sound is emitted when changes are detected in the object's motion during a throw.
  • the speaker may emit a sound when the object is moving through the air and reaches a certain height, or speed, or when the object is thrown in a certain way such that its motion, e.g. spin meets the aims of a game.
  • the player can be rewarded by audible feedback during the throw, rather than waiting to catch the object and then looking to see what information, e.g. maximum height is displayed after the event. This makes throwing games more enjoyable.
  • the experience can be more intense as players hear feedback about each other's throws during the game.
  • the speaker is arranged to emit a sound when the processor determines a difference that exceeds or equals a predetermined threshold.
  • a predetermined threshold that correspond to travel data of interest may be programmed into the processor. For example, the object reaching a certain height from the ground, or a certain speed, or a particular type of throw being achieved.
  • the processor is arranged to determine whether the throw is one or more of an air throw, arc throw, high spin throw, straight horizontal throw, overarm throw, an underarm throw, a side throw, a baseball throw, a running throw, a stationary throw, a spiral throw, a straight vertical throw or other type of throw by comparing the measured travel data to predetermined travel data point(s) that uniquely describe each of the different types of throw.
  • the speaker may be arranged to emit one or more different sounds corresponding to features of interest in the motion of the object during a throw.
  • the sound emitted by the speaker is different to an earlier sound emitted by the speaker prior to the processor determining the difference.
  • the body can further house (or comprise) a memory storing one or more, and preferably a plurality of, different digital sound files. These sound files can be accessed by the processor for output using the speaker. Each sound file may be associated with one or more different features of interest in the motion of the object during a throw and/or different types of throw (e.g. using a database structure stored in the memory), so that the processor can select the sound file corresponding to the determined feature of interest or type of throw, and output the sound corresponding to the selected sound file.
  • sound files can be added or deleted from the memory, and/or the stored associated between a sound file and a feature of interest or type of throw can be changed (e.g. by a user on an app on their smartphone that is connected, e.g. wirelessly, to the throwable object. As will be appreciated, this allows new sounds to be output by the object over time, and allows different throwable objects to be uniquely configured by a user.
  • the sound emitted by the speaker is desirable for the sound emitted by the speaker to provide an indication of the current motion of the object during a throw. Accordingly it is preferable that the recent travel data measurement is a current travel data measurement from the IMU. This means that the feedback given to a user may be almost instantaneous. It is also desirable for the feedback to be updated on a regular basis, for example so that different sounds are emitted if there are changes in the motion of the object during a throw.
  • processor may be arranged to, based on the travel data, determine a phase of flight of the throwable object and may emit different sounds, each of the different sounds being assigned to one or more different phases of flight. Accordingly it is preferable that the previous travel data measurement is the most recent travel data measurement preceding the current travel data measurement.
  • the difference may comprise a change in (absolute or relative) magnitude for the travel data, or a change in time, for example a rate of change for the travel data, or a second or further derivative with respect to time.
  • other differences may be used to trigger when the speaker emits a sound.
  • the inertial measurement unit may be any electronic device that can measure the linear and/or angular acceleration experienced by the body when the object is in motion.
  • the IMU comprises an accelerometer, a gyroscope, and optionally a geomagnetic field sensor, arranged to measure one or more of the object's position, speed, height, acceleration, velocity, angular rate, roll, pitch, or yaw.
  • the I MU may comprise up to three accelerometers and up to three gyroscopes.
  • a geomagnetic field sensor or magnetometer is any device that can measure the Earth's magnetic field and hence assist in calibration against orientation drift.
  • the processor may be arranged to process the travel data as necessary to calculate parameters such as position, speed, and/or height. For example, acceleration data can be integrated over time to provide the speed of the object and/or calculate a relative height change during the throw.
  • the barometric pressure sensor may be any electronic device that can measure atmospheric pressure. Such sensors are also known as pressure altimeters or altitude meters. In a preferred set of embodiments the barometric pressure sensor is arranged to measure the height of the object based on an atmospheric pressure measurement. Typically, such a sensor may allow for height measurements with an accuracy of ⁇ 1 0cm.
  • a barometric pressure sensor provides benefits over an IMU for height measurement, because it can measure the height of the object relative to the ground during a throw. This avoids the need for manual input of a starting height for the object before the throw. It is also made easier for the processor to calculate a cumulative height for multiple throws.
  • the barometric pressure sensor further comprises a temperature sensor, and is arranged to measure the height of the object based on an atmospheric pressure and temperature measurement. This improves the accuracy of the height measurement.
  • the throwable object may comprise one or more further sensors to assist in measuring travel data of interest.
  • the body further houses a capacitive proximity sensor arranged to measure a change in capacitance at the surface of the body.
  • a capacitive proximity sensor can provide measurements that advantageously enable the processor to detect the difference between the object being caught and hitting the ground (not caught). Such detection may be improved if the object is provided with a clearance between the capacitive proximity sensor and the location where the hands may hold the object, such as a non-metallic, or more generally, a non-conducting shell.
  • a measurement of deceleration from the IMU does not distinguish between the different ways that the object reaches the end of a throw, i.e.
  • the processor is arranged to determine that the object is in touch-contact, or has been thrown, based on the measured change in capacitance.
  • the processor optionally by using the travel data, may be arranged to determine that or distinguish whether the object is in-flight, is being thrown, is being caught, is hitting the ground, is being hand-held or has been resting on the ground. Such determination or distinction may be improved if the object is provided with a clearance between the capacitive proximity sensor and the location where the hands may hold the object, such as a non-metallic, or more generally, a non-conducting shell.
  • the processor may be arranged to record progression of a game.
  • a game is a game in which the object is repetitively thrown by one of a predetermined number of users, typically two, to another one of the users and in which based on measurements by the proximity sensor and/or on the travel data the processor records an amount of catches before the object is being dropped.
  • a throwable object comprising: a body housing a capacitive proximity sensor arranged to measure a change in capacitance at the surface of the body; and a processor arranged to determine that the object is in touch-contact, or has been thrown, based on the measured change in capacitance.
  • the electrically conductive surface may be part of a user's body or part of another object that catches the object, for example a net or goal comprising a conductive mesh. Such touch-contact is therefore distinguished from the object landing on the ground. What is meant by the object having been thrown is that the surface of the body has left contact with another electrically conductive surface, such as a user's hand, so as to generate a recognisable change in capacitance.
  • a capacitive proximity sensor is a capacitive touch sensor that can sense not only physical touch but also touch within a predetermined proximity range.
  • the capacitive proximity sensor has a proximity range of at least 5 cm and preferably 1 0 cm or more.
  • the capacitive proximity sensor may conveniently be located on a printed circuit board mounted inside the body and there is no need to arrange capacitive sensors on the surface of the body.
  • the processor is arranged to determine that the object is in touch-contact when the capacitive proximity sensor measures a change in capacitance that equals or exceeds or falls below a predetermined threshold. In a set of embodiments the processor is arranged to determine that the object is in touch-contact, or has been thrown, when the capacitive proximity sensor measures a change in capacitance that is inside a predetermined threshold range.
  • the processor is arranged to determine that the object is in touch- contact, or has been caught, when the capacitive proximity sensor measures a change in capacitance that equals or exceeds a predetermined threshold, or measures a change in capacitance that is inside a predetermined threshold range.
  • the predetermined threshold or threshold range is set to indicate that the object is in touch-contact because it is being held by a user or it has been caught, or to indicate that the object has been thrown because the object is no longer being held by a user. Changes in capacitance may conveniently be used to assess the way in which the object is caught, for example in one hand or both hands.
  • the capacitance measurements can be used by the processor to decide when to take into account the travel data measurements received from the throw sensor.
  • the processor may be desirable for the processor to integrate the acceleration measured by the throw sensor only from the point in time that the object, e.g. ball leaves the hand. Detecting when the ball is being held and when it has left the hand can minimise the anomalies in accelerometer measurements and improve IMU accuracy.
  • the processor is arranged to process the travel data measurements received from the throw sensor depending on when the object is determined to be in touch-contact and/or to have been thrown.
  • the throw sensor is also arranged to periodically measure travel data describing the motion of the object before and/or after the object has been thrown; and the processor is arranged to determine that the object is in touch-contact, and/or that the object has been thrown, further based on a travel data measurement, or a difference between a current travel data measurement and a previous travel data measurement.
  • the travel data measurements from the throw sensor may also be used to assess the motion of the object before and/or after the object has been thrown.
  • measurements from the capacitive proximity sensor are also used to provide an audible feedback.
  • the speaker is arranged to emit a sound when the processor determines that the object is in touch-contact. It is further desirable for the processor to use the measurements from the capacitive proximity sensor to assist in analysing the motion of the object during a throw.
  • the processor is arranged to evaluate the travel data measurements from a time when the processor detects that the object has been thrown to a subsequent time when the processor detects that the object is in touch-contact so as to evaluate travel data describing the motion of the object during a throw.
  • the processor is arranged to determine the distance between the position of the object at the time when the object was thrown and the position of the object at the time when the object was in touch-contact based on the travel data measurements.
  • the processor is preferably arranged to determine the maximum height of the object between the time when the object was thrown to the time when the object was in touch-contact based on the travel data measurements.
  • the maximum height is relative to the height of the object at the time when the object was thrown.
  • the processor is preferably arranged to count the number of full rolls or partial rolls the object makes during the throw based on the travel data measurements.
  • the speaker may be housed in the body in any suitable arrangement as long as the sounds emitted by the speaker are audible to a user of the throwable object.
  • the Applicant has appreciated that it can be beneficial to arrange the speaker such that its impact on throwability of the object is minimised.
  • the body comprises a major axis, and the speaker has a centre of mass that is substantially centred on the major axis. This means that the speaker does not alter the normal centre of mass of the object.
  • the position of the speaker can affect how sound is emitted from the body and its audibility during use.
  • the object has a shape dictating the direction in which it is normally thrown, for example a vortex football
