Theelectronic device 2 can also be a cloud server. - The sportball 1 includes a
ball body 10, a number ofsensors 20, and acontroller 30. Theball body 10 is made of elastic material such as rubber. Thesensors 20 are located in and arranged at different locations in theball body 10. When theball body 10 is pressed by a user (taking a basketball for example, when the user's hand touches the basketball during dribbling or shooting the basketball), the user applies an original and external pressure, such original and external pressure to be delivered from theball body 10 to at least onesensor 20, and then sensed by the at least onesensor 20. - The
sensors 20 sense pressures at different locations of theball body 10, and generate electrical signals according to the sensed pressures. Thecontroller 30 is located inside theball body 10, and is electrically connected to each of thesensors 20. Thecontroller 30 obtains the generated electrical signals, and determines a characteristic data of the pressures applied according to the obtained electric signals. Since thesensors 20 are located in theball body 10, theball body 10 may absorb a portion of the original pressures to cause the pressures sensed by thesensors 20 to be less than the original pressures. In at least one embodiment, the elastic material of theball body 10 has a moderate elasticity. As such, theball body 10 can have enough elasticity to effectively reflect the amount of the original pressures. That is, theball body 10 can effectively deliver the original pressures to thesensors 20, to cause the amount of the pressures sensed by thesensors 20 to be nearly identical to the original pressures. - In at least one embodiment, the
sensors 20 include pressure sensors, such as piezoelectric sensors or capacitive type sensors. The pressure sensors sense the value of the pressures, and generate electric signals according to the sensed value of the pressures. Thecontroller 30 obtains the generated electrical signals, and determines the value of the pressures according to the obtained electric signals. That is, the determination of the characteristic data of the pressures applied to the sportball 1 being handled or struck includes the value of the pressures. In addition, thecontroller 30 further determines a range of the area to which the pressures are applied and sensed according to thesensors 20 which generate the electrical signals, and determines a posture of the employed by the user to theball body 10 according to the determined range. That is, the determination of the characteristic data of the pressures further includes the posture employed by the user. - The
sensors 20 can further include motion sensors such as three-axis gyroscopes, gravity sensors, or acceleration sensors. The motion sensors sense the direction of the pressures, and generate electrical signals according to the sensed direction of the pressures. Thecontroller 30 obtains the generated electrical signals, and determines the direction of the pressures according to the obtained electric signals. That is, the determination of the characteristic data of the pressures includes the direction of the pressures. The motion sensors can further sense the acceleration and the velocity of theball body 10 as a result of the pressures.

electronic device 2 includes aprocessor 22. When theelectronic device 2 receives the determined characteristic data from the sportball 1, theprocessor 22 compares the determined characteristic data with data as to a certain standard (standard data), and generates feedback information according to the result of comparison.

When the user' handling or striking is not correct, thecontroller 30 controls theLEDs 32 to emit light of high intensity to indicate error or non-correctness in handling or striking Otherwise, thecontroller 30 controls theLEDs 32 to emit light of low intensity. As such, the user can learn visually. In this embodiment, the elastic material used to make theball body 10 is transparent to allow the emitted light to be seen. - In at least one embodiment, the sportball 1 is spherical, for example, a football, a baseball, a basketball, or a golf ball. The
ball body 10 includes aspherical exterior surface 11 and an oppositeinterior surface 12. Theball body 10 is divided into aball wall 101 between the exterior 11 and theinterior surface 12, and acavity 102 surrounded by theinterior surface 12. Theball wall 101 is made of elastic material.
