A mobile communication terminal is disclosed that is capable of utilizing detection result data obtained by detection means for detecting position, direction, attitude and/or movement in a platform-independent application program that can be registered and used by users. When downloading an application program to a mobile communication terminal and executing it, first, the application execution environment is activated and the application program is executed under the environment. The started application program sends an acquisition request for acceleration data to the phone platform. When the phone platform accepts the acquisition request, it passes acceleration data detected by an acceleration sensor to the application program. Accordingly, the application program can perform a process utilizing the acceleration data.

Mobile communication terminal and application program

An electronic apparatus includes key operation means, control means, detection means, storage means and memory means. The detection means detects motion of the electronic apparatus. The storage means stores motion identification data obtained from detection data on a motion after a predetermined key operation in the key operation means after predetermined guidance information is outputted or data obtained by computing the detection data, in the memory means. The control means executes the specific process according to the comparison results between detection data obtained by detecting a motion of the electronic apparatus after the motion identification data is stored or data obtained by computing the detection data, and the motion identification data.

Electronic apparatus

A mobile communication terminal includes detection means that detects at least one of the position, orientation, attitude, and motion of a mobile communication terminal. Application program execution means can concurrently perform two direction changing processes different from each other according to two direction parameters by executing an application program, and determines at least one of the two direction parameters based on detection data detected by the detection means. The two direction changing processes are, for example, a visual point moving direction changing process for changing a moving direction of a visual point for viewing an image on a display means and a visual line direction changing process for changing a visual line direction. One of the direction parameters may be determined based on a key operation signal from key operation means.

Acceleration and attitude angles are measured by sensors mounted on a moving object and the measurement results are collected. The measurement results of acceleration are separated into low-frequency acceleration components and high-frequency acceleration components, and a time-rate-of-changes of attitude angles are calculated based on the measurement results of the attitude angles. After finishing extraction of the high-frequency acceleration components and the low-frequency acceleration components, and finishing calculation of the time-rate-of-changes of attitude angles, the rotation contributing acceleration and translation contributing acceleration are estimated based on the high-frequency acceleration components, the low-frequency acceleration components, the attitude angles and the time-rate-of-change of attitude angles. As a result, a translation contributing acceleration which contributes to a translational movement of a moving object, and a rotation contributing acceleration which contributes to a rotational movement of the moving object are estimated with improved accuracy.

When an acquisition and reporting control unit of a measurement data processing unit in a development support device sends a sensor measurement start request to a portable information device in response to a collection operation start command from an application under development, an acquisition and reporting control unit of a measurement data processing unit in the portable information device starts measurement operations by a sensor. The measured raw data is continuously sent to the development support device. Data which match the collection condition are collected by a data collection unit. In response to a data request from the program under development, a data reporting unit reports the measurement data which satisfy a reporting condition to the application under development. As a result, when developing an application program which uses the results of measurement by the sensor, it is possible to provide a satisfactory development environment.

Program development system

An electronic apparatus includes program memory means, application program execution means, and attitude detection means. The program memory means stores a plurality of application programs. The application program execution means executes an application program read out from the program memory means. The attitude detection means detects the attitude of the electronic apparatus. The application program execution means performs an application switching process to execute a second application program when detection data obtained by attitude detection performed by the attitude detection means during execution of a first application program or data obtained by computing the detection data changes across a predetermined threshold.

Application switching within electronic apparatus

In a measured-value converting process, a shape-condition converting process and an absolute coordinate system converting process (S) are performed on a value measured by a sensor. In the shape-condition converting process, when a mobile terminal has a shapeand shape, the converting process is not performed (Sand S). When the mobile terminal has a shape, a converting process of rotating through 180&#xb0; around Yaxis is performed (S). Moreover, when the mobile terminal has a shape, a converting process of rotating through 180&#xb0; around Zaxis (S) is performed. Therefore, even in an information processing apparatus of which a shape changes, a sensor which detects a movement of the information processing apparatus can be used as an input device, irrespective of the shape.

A motion sensor which can easily and accurately detect bearing, attitude and acceleration in any of three-dimensional directions and a portable telephone using the same. The motion sensor comprises three magnetic sensing parts for detecting magnetic field strength in 3-axis directions orthogonal to one another, and three acceleration sensing parts for detecting accelerations in the 3-axis directions. Each of the acceleration sensing parts has a magnet body constituted to be able to displace depending on acceleration, and a magnet displacement detection head for detecting a displacement of the magnet body. The three magnetic sensing parts and the three magnet displacement detection heads are all made of the same type of magnetic detection elements which operate based on common operation principles. The three magnetic sensing parts and the three acceleration sensing parts are integrated into one modular package together with one electronic circuit for controlling these six magnetic detection elements.

When, from a standby screen of a terminal device, a user depresses a motion key (S) and performs a registered movement (S), a sensor unit observes the movement of the terminal device, and a movement parameter calculation unit calculates a movement parameter. A movement parameter change decision unit decides (Sand S) whether or not a change of the movement parameter which is calculated, and a change of the movement parameter corresponding to a predetermined function registered in advance, agrees with one another. If the result of this decision is affirmative, a function control unit starts the corresponding function (S). As a result, it is possible to set the terminal device to a state in which the predetermined function can be employed, with a simple and easily remembered actuation.

A measured physical quantity calculating partcalculates a measurement result-corrected value obtained by correcting a measurement result of a sensor unitby the use of corrected values for the sensor unit. Subsequently, a measurement environment estimating partestimates a terrestrial magnetism measurement environment on the basis of at least one measurement result-corrected value. The estimation result is displayed on a display unitby an estimation result display part. In this way, the terrestrial magnetism measurement environment is first estimated and then the terrestrial magnetism is measured by the use of the sensor unit. That is, it is possible to measure the terrestrial magnetism by the use of a magnetic sensor mounted on a mobile information device after estimating the terrestrial magnetism measurement environment.
