Embodiment Construction

[0069] The invention relates to a posture sensing device for sensing the posture of an object and a motion sensing device for sensing the variation of the posture of the object. Attitude and motion sensing devices include three-axis magnetic sensors and two-axis or three-axis accelerometers. More precisely, the input signals are generated by attitude and motion sensing devices (three-axis magnetic sensors and two- or three-axis accelerometers).

[0070] Magnetic field sensing device

[0071] The spatial attitude of the rigid body 10 can be described as three angles: heading angle, roll angle and pitch angle (see Figure 1). Generally, these angles take the local horizontal plane as a reference plane, for example, a plane perpendicular to the gravity of the earth or is the ecliptic plane of the Earth. The heading angle (α) refers to the included angle between the direction of the nose of the rigid body 10 clockwise from the true north direction on the local horizontal plane. ...

Abstract

The invention provides an attitude of using such portable device as mobile phone and game devices etc. and a motion induction system. The system comprises a two-axis or three-axis accelerometer and a three-axis magnetic sensor such as a magnetic compass which can be arranged integrally in the portable electronic device. The attitude angle and the rotation angle of the attitude data obtained from the accelerometer and the magnetic sensor are calculated by a data processing unit, and then are changed into input signals for special application procedures of the portable electronic device.

Description

technical field [0001] The invention relates to the input technology of electronic components, especially the electronic components or devices that can generate input signals matching their postures, or realize the input signals changing with postures through their own application programs. Background technique [0002] Portable devices include portable wireless devices, such as mobile phones, mobile phones, cordless phones, text messaging devices, pagers, walkie-talkies, portable navigation systems, pocket music players, portable DVD players, portable multimedia devices, handheld computers, and small games. increasingly common in daily life. With the development of science and technology, the application range of portable electronic devices is becoming wider and wider, and the degree of integration is getting higher and higher, while the volume and weight are getting smaller and smaller. Generally, the user's command input and power supply often occupy most of the volume a...
