Brief Description of the Drawings [0057] Example embodiments should become apparent from the following description, which is given by way of example only, of at least one preferred but non-limiting embodiment, described in connection with the accompanying figures. [0058] Figure 1 is a system diagram of an example system including a rotatable device in communication with a computer application executing upon a processing system; - 10 [0059] Figure 2 is a system diagram of another example system including a rotatable device in communication with a client application executing upon a client processing system in communication with a server application executing upon a server processing system; [0060] Figure 3 is a circuit diagram of an example electrical circuit of the rotatable device. Detailed Description of Preferred Embodiments [0061] The following modes, given by way of example only, are described in order to provide a more precise understanding of the subject matter of a preferred embodiment or embodiments. [0062] Referring to Figure 1 there is shown a system diagram of an example system 100 using a rotatable device. In particular, the system 100 includes a rotatable device and a computer application 210 executable upon a processing system 200. The rotatable device is generally a toy hoop, although as will be discussed in further embodiments herein, other non-hoop profiles of the rotatable device are possible. The rotatable device includes an aperture for receiving therethrough a user's body part such as a limb, waist, or the like. [0063] Referring more specifically to Figure 1, the rotatable device includes a microcontroller 120 attached to the body, a gyroscope 140 attached to the body and electrically connected to the microcontroller 120, an accelerometer 130 attached to the body and electrically connected to the microcontroller 120, a communication module 150 electrically connected to the microcontroller 120, and an electrical power supply 160 in electrical connection with the microcontroller 120 and optionally one or more of the above mentioned electrical components if required. The microcontroller 120 generally includes a microprocessor, a memory, and an input/output interface interconnected via a bus. [0064] An example circuit diagram of the electrical components of the rotatable device are shown in Figure 3. In one specific embodiment, the microcontroller is a - 11 Arduino Pro Mini 328 (3.3V/8MHz), the communication module is a EGBT-04 Bluetooth module, and the accelerometer and gyroscope are provided in an integrated module in the form of a MPU-6050 Accelerometer and Gyroscope module having a 3-axis gyroscope and a 3-axis accelerometer. It will be appreciated by those skilled in the art that these are only exemplary electrical components and that other components can be used. [0065] In use, rotation of the rotatable device about the user's body part causes the microcontroller 120 to collect sensor data from the gyroscope 140 and accelerometer 130, and transfer data indicative of the sensor data to the processing system 200 executing the computer application 210 which is responsive to the received data. As such, the user is in certain embodiments able to effectively control the computer application 210 via physical rotation of the rotatable device about the user's body part. [0066] In particular embodiments, the rotatable device includes a kinetic recharger 180 in electrical connection with the electrical power supply 160. As the user rotates the rotatable device, the kinetic charger 180 converts kinetic energy into electrical energy which is then used to recharge the portable power supply 160 via a recharging unit 170. The kinetic recharger 180 thereby extends the operating lifetime of the rotatable device without requiring recharging via an external power supply which can be coupled to a recharging port 175 of the recharging unit 170. The recharging port 175 may be a USB port which enables a USB cable to be electrically coupled to a USB enabled electrical device such as a processing system or the like. [0067] Preferably, the microcontroller 120, the gyroscope 140, the accelerometer 130, the communication module 150 and the kinetic recharger 180 are housed within the body of the rotatable device. In particular, the body can include a cavity within a tubular structure which houses the electrical components therein in a tight fitting manner. The electrical components can be embedded or protected within a foam material when housed within the body to provide protection from collisions with external objects. In certain embodiments, the body has a circular profile, such as a hoop profile. However, in other - 12 embodiments, the body can include a non-circular profile to provide a different challenge to more traditional circular profiles. [0068] The communication module 150 preferably is a wireless communication module 150 which utilises wireless data communication to transfer data indicative of the sensor data to the processing system 200. In one preferable form, the communication module 150 utilises Bluetooth protocol to wirelessly transfer the data to the processing system 200. [0069] In a preferred form, the microcontroller 120 streams the sensor data to the processing system 200. The processing system 200 can then analyse the received data to determine a rotation count. The rotation count is a value indicative of a number of rotations of the rotatable device about the user's body part or a number of rotations of the user's body part about an axis. The analysis of the sensor data generally includes fusing the accelerometer 130 data with the gyroscope 140 data to determine the rotation count. [0070] In a specific form, the processing system 200 maintains a rotation counter in memory which is incremented upon the detection of each rotation. The rotation counter can be incremented and maintained for a particular operating session. The operating session may be a user defined operating session wherein the user interacts with the processing system 200 to start a session such that rotations that are performed by the user thereafter are recorded by the processing system 200 until the user interacts with the processing system 200 to end a session. In one form, the computer application 210 operating upon the processing system 200 may include a user interface which can be interacted with via an input device to start and end a session. [0071] In another form, the processing system 200 may automatically detect and define an operating session. In particular, the processing system 200 analyses the data received from the microcontroller 120 of the rotatable device to determine the start and end of the operating session. The processing system 200 can compare the received data against one or more thresholds to determine at least one of the start and the end of the session. For - 13 example, the data may be timestamped, wherein a temporal threshold between rotations may indicate a start or end session. Alternatively, an acceleration or velocity threshold can be used to detect a significant change in acceleration and/or velocity of the rotating device to indicate a start and/or end of the operating session. In a further form, the user may move the rotatable device in a particular manner to indicate the start or end of an operating session. For example, the user may rotate the rotatable device similar to operating a steering wheel of a car to indicate the start and end of an operating session, wherein the sensor data can be analysed by the processing system 200 to detect such a gesture by the user using the rotatable device. [0072] In a preferable form, the processing system 200 is a mobile processing system 200 such as a mobile communication device (smartphone, tablet processing system, etc). The processing system generally includes a processor, memory, one or more input/output devices, a wireless communication module coupled together via a data bus. The processing system can be operated by the user to download the computer application 210 from a computer application server processing system. [0073] The computer application 210 can be provided in the form of a computer game. In particular, the user is able to provide input to the control an aspect of the computer game via rotation of the rotatable device. For example, the computer application 210 may control a character in response to the detected rotations. In an alternate form, the computer application 210 may be an exercise computer application which monitors exercise and work performed by the user in response to the detected rotations. In particular, the exercise computer application may be used to measure the calories burnt by the user during a session, a top speed/revolutions for a particular duration of the rotatable device about the user's body part, and/or gradual progress. [0074] The computer application executed by the processing system can be configured to determine the velocity of the rotatable device about the user's body part by determining the acceleration of the rotatable device using the sensor data from the accelerometer and then integrating the acceleration by time. Once a velocity has been determined by the - 14 computer application, the velocity is used to determine a distance value which is indicative of the distance which the rotatable device rotates about the user's body part. For example, in the event that the rotatable device is spun around a user's waist, the distance value calculated is indicative of the distance which a point on the rotatable device travels around the user's waist. The processing system has stored in memory a variable indicative of the circumference of the user's body part, wherein the computer application divides the distance travelled by the circumference of the user's body part to determine the rotation counter. This process can be performed by the computer application in real-time such that the rotation counter is incremented in real-time. However, it is also possible that this process can be performed by the computer application in a single step once the session has been detected as ending. It will be appreciated that the user can interact with the processing system to input and save in memory the user's circumference of one or more body part's for rotating the rotatable device thereabout. [0075] The computer application executed by the processing system can also be configured to determine the orientation of the hoop in 3D space. In particular, the gyroscope senses the acceleration in three orthogonal directions allowing for the orientation of the hoop to be determined. The calculation can be determined by the gyroscope or alternatively, the acceleration data can be transferred to the computer application executed by the processing system to calculate the hoop orientation. In particular, the computer application can use the acceleration data to determine whether the z-axis acceleration of the hoop is substantially equal to 9.81 ms-2 to determine if the hoop is horizontal. The computer application can compare the determined hoop orientation against an orientation threshold range stored in memory to determine whether the hoop is being rotated about the user in a desired orientation. For example, in the event that the computer application requires that the hoop is rotated about the user's waist, the computer application can compare the determined orientation against the threshold range to determine if the user is correctly rotating the hoop. In the event that, for example, the user is rolling the hoop on the ground, then the orientation checking process performed by the computer application can detect this operation of the hoop and stop incrementing the - 15 rotation counter. The orientation checking process can be performed periodically or at specific time intervals whilst the accelerometer detects movement of the hoop. [0076] In the event that the rotatable device collides with another object, the data transmission from the microcontroller to the processing system may temporarily stop. The computer application can be configured to detect a break in data transmission which meets or exceeds a temporal threshold (e.g. 5 secs), wherein upon successful detection, the computer application controls the communication module of the processing system to re establish a handshaking process with the communication module of the rotatable device such that data transmission can once again take place. Thus, in the instance of Bluetooth protocol, the detection of a break in transmission can result in the processing system attempting to repair with the Bluetooth module of the rotatable device. [0077] Referring to Figure 2, there is shown a system diagram of another example system 100. The processing system 200 of the system 100 of Figure 2 is in data communication, via one or more computer networks such as the Internet, with a server processing system 300 executing a server application 310. In this regard, the processing system 200 is considered a client processing system 200 which executes a client application 210 which interfaces with the server application 310 executing upon the server processing system 300. In use, rotation of the rotatable device about the user's body part causes the microcontroller 120 to collect sensor data from the gyroscope 140 and accelerometer 130, and transfer data indicative of the sensor data to the client processing system 200 executing the client application 210 which in turn interfaces with the server application 310, using the received data, to request a server operation to be performed. [0078] In certain embodiments, the server application 310 is a social media server application operated by a third party, such as Facebook, Twitter or the like. The client application 210 is configured to generate and transfer a post request to the server application 310 executing upon the server processing system 300. The post request may include information indicative of the data received from the rotatable device by the client processing system 200, wherein the information is published in the social media post for - 16 the user. For example, the information may be indicative of textual data representing a length of time that the rotatable device was rotated and/or a number of rotations of the rotatable device or the user's body part about an axis. [0079] Whilst it is possible, as discussed in relation to the system of Figure 1, for the client processing system to perform the analysis of the data received from the rotatable device, it is also possible that the client processing system can act as a relay device and forwards the received data to the server processing system for analysis. [0080] In one variation, feedback data may be generated by the processing system 200 and transferred to the microcontroller 120 of the rotatable device. The rotatable device can include one or more output devices 190 in electrical communication with the microcontroller 120 for providing visual, audio and/or tactile feedback to the user. For example, the one or more output devices 190 can include one or more light emitting diodes which are selectively actuated by the microcontroller 120 in response to the received feedback data. The light emitting diodes can be flashed in a particular manner or can be actuated to emit one or more different colours of light to indicate particular forms of feedback (i.e. green lights may indicate speed up, red lights may indicated slow down). The one or more output devices 190 can additionally or alternatively include one or more vibration modules in electrical communication with the microcontroller 120, wherein the microcontroller 120 actuates the one or more vibration units in response to the received feedback data. The one or more output devices 190 can additionally or alternatively include one or more speakers in electrical communication with the microcontroller 120, wherein the microcontroller 120 actuates the one or more speakers to emit audio in response to the received feedback data. The one or more output device 190 can be housed within the body of the rotatable device. In a preferable form, in the event that multiple output devices 190 are housed within the body of the rotatable device, the multiple output devices 190 can be equally displaced about the body of the rotatable device. [0081] In an optional form, due to the weight of the electrical components housed within the body, the electrical components can be substantially evenly distributed and -17 dispersed throughout the body in order to more evenly distribute the weight of the electrical components within the body. For example, a first portion of the electrical components may be housed diametrically opposite to a second portion of the electrical components, wherein electrical wire can extend throughout a portion of the body to interconnect the two portions of the electrical components. In an additional or alternate form, weights may be incorporated into the body to evenly distribute the weight of the rotatable device about an axis which the rotatable device is configured to rotate thereabout. [0082] The arrangement of the system 100 illustrated in Figure 2 can be adopted to enable multiple users to compete in a computer game in a distributed manner. For example, data transferred to server processing system 300 from a first rotatable device via a first client processing system 200, and in response the server processing system 300 can transfer data to a second client processing system 200 associated with a second rotatable device operated by a second user.
