In that case, if the frequency of positioning is set for every few steps, positioning is frequently performed, and the power consumption of the electronic device 1 increases. Therefore, it is desirable to set the frequency of positioning, for example, every several hundred steps.
- the point P2 has advanced 300 points from the point P1, and has further advanced 300 points from the point P2.
- An example will be described in which a user moves along a route to home H via a point P3, a boarding point P4 at which the user gets on the car, and a boarding point P5 at which the user gets off the car.
- the electronic device 1 is set to have a first positioning frequency so that positioning is performed every time the number of steps the user walks reaches 300 steps.
- the frequency of positioning is set in a conventional electronic device, the first frequency of positioning is not changed. This case will be described below.
- the user performs positioning at the points P2 and P3.
- the positioning of the boarding point P4 may be performed when the boarding determination unit 12 determines that the boarding is performed on the vehicle.
- the user hardly walks because he is in the car. Therefore, the number of moving steps does not reach 300 steps, and the user's positioning is not performed at the getting-off point P5. Furthermore, for example, when the distance is about 20 steps from the getting-off point P5 to the home H, the number of moving steps does not reach 300 steps even considering the number of moving steps from the boarding point P4. Therefore, even if the home is the destination, positioning of the destination is not performed and the user may not be determined to have arrived at the destination.
- the frequency switching unit 14 switches the frequency of positioning from the first frequency to the second frequency.

- the position where the user got off can be accurately grasped by acquiring the position information after detecting the walking of 20 steps after boarding determination.
- this makes it possible to correctly determine the location information of the destination even when the distance is about 20 steps from the getting-off point P5 to the home (destination).
- the second frequency higher than the first frequency, it is possible to realize the electronic device 1 that can measure the correct position when getting off and that has low power consumption.
- the electronic device 1 may have a configuration for detecting getting off when detecting the number of steps reaching the second predetermined value.
- the frequency at which the position information acquisition unit 21 acquires the position information may be switched from the second frequency to the first frequency.
- positioning at the second frequency positioning every 20 steps

- the frequency switching unit 14 may switch the frequency of acquiring the user's position information from the first frequency to the second frequency again.
- the first frequency is set to every 300 steps (first predetermined value)
- positioning is performed about once every two to three minutes.
- acquisition of position information can be thinned out, and power consumption can be reduced.
- the position information can be obtained once every 200 m, it can be determined that there is no problem with the accuracy of the position information such as GPS.
- the second frequency is set to every 20 steps (second predetermined value)
- positioning is performed about once every 10 seconds.
- alighting position can be pinpointed correctly by walking and the accuracy of positioning of alighting position can be improved.
- the home can be correctly determined.
- the present invention is not limited to the above, and the second frequency is lower than the first frequency. Also good. For example, when using a station that cannot be measured by GPS every time, such as when using the subway, if the second frequency is set higher than the first frequency, positioning is frequently performed until position information can be acquired. There is a problem that power consumption increases. Therefore, for example, by setting the second predetermined value of the second frequency to 500 steps so that positioning is performed at the timing when the second frequency gets off the train and goes on the ground, the above problem can be avoided, and low power consumption Can be realized. In other words, the second frequency can be set by the user in accordance with the behavior pattern. Moreover, you may have the structure which learns the location which could not be measured in multiple times and changes the setting of 2nd frequency.

It may be determined whether or not the vehicle being moved is in a boarding movement state. In other words, the boarding determination unit 12 further determines whether or not the user is in a boarding movement state in which the user gets on the vehicle and the vehicle is moving.
- a state that is not in the boarding movement state (a state other than the boarding movement state) means that the user is standing without walking on the vehicle, is walking, the user is trying to get into the vehicle, and gets off the vehicle. And the like.
- the boarding determination unit 12 acquires, for example, a sensor value according to the movement state of the user by the sensor unit 2 every predetermined time, and comprehensively from the sensor value according to the movement state acquired within a certain time.

図1は、本実施形態に係る電子機器1の概略構成を示すブロック図である。電子機器1は、ユーザの位置情報を取得し、乗物の乗車位置や降車位置、ユーザが移動したルートを示す行動情報等をユーザに報知する。
測位指示部10は、連続歩行検出部11、乗車判定部12、歩数計数部13、頻度切替部14、および頻度設定部15が備えられている。
ホスト制御部20は、位置情報取得部21および報知部22を備えている。ホスト制御部20は、1つ以上の回路によって構成されている。ホスト制御部20は、CPU(Central Processing Unit)、ROM(Read Only Memory)、RAM(Random Access Memory)等を備えて構成されており、ROM、RAM等に記録されているプログラムをCPUが実行することにより、電子機器1の各部を制御する。
第1頻度および第2頻度の設定例について図2を用いて、下記に説明する。図2は、電子機器1における測位の概要を説明するための図であり、図2の(a)は従来の電子機器での測位を示し、図2の(b)は電子機器1での測位を示す。
図3は、電子機器1にて実行される測位処理の流れを示すフロー図である。電子機器1の起動が完了しセンサ部2が歩行を検知した場合、または所定の時間毎に、図3に示す処理を行う。まず、連続歩行検出部11は連続歩行であるか否かを判定する(S11、乗車判定ステップ)。センサ部2で検知した歩行が連続歩行であった場合(S11でYES)、乗車判定部12は、ユーザが乗物に対して乗車を行ったか否かを判定する(S12)。ユーザが乗物に対して乗車を行っていた場合(S12でYES)、頻度切替部14は、頻度設定部15において設定されている位置情報取得部21が位置情報を取得するタイミングを第1頻度から第2頻度に切替える。すなわち、設定されている歩数値を第1所定値から第2所定値に切替える(S13、頻度切替ステップ)。その後、頻度設定部15は、歩数計数部13で計数された歩数が第2所定値に達したか否かを判定する(S14)。歩数計数部13で計数された歩数が、第2所定値に達した場合(S14でYES)、頻度設定部15は、位置情報取得部21に位置情報を取得させる。言い換えると、電子機器1はユーザの位置を測位する(S15、位置情報取得ステップ)。
本発明の実施形態2について、図4および図5を参照して説明する。図4は、本発明の実施形態2に係る電子機器1Aの概略構成を示す機能ブロック図である。図4に示す電子機器1Aは、電子機器1に比べて、測位指示部10に代えて、測位指示部10Aが設けられる点が異なり、その他の構成は同様である。

図5は、電子機器1Aにて実行される測位処理の流れを示すフロー図である。電子機器1の起動が完了しセンサ部2が歩行を検知した場合、図5に示す処理を行う。まず、連続歩行検出部11は連続歩行であるか否かを判定する(S21)。センサ部2で検知した歩行が連続歩行であった場合(S21でYES)、乗車判定部12は、ユーザが乗物に対して降車を行ったか否かを判定する(S22)。ユーザが乗物に対して降車を行っていた場合(S22でYES)、頻度切替部14aは、頻度設定部15aにおいて設定されている位置情報取得部21が位置情報を取得するタイミングを第1頻度から第2頻度に切替える。すなわち、設定されている時間を第1所定時間から第2所定時間に切替える(S23)。その後、頻度設定部15aは、時間計測部16で計測された時間が第2所定時間を経過したか否かを判定する(S24)。時間計測部16で計測された時間が、第2所定時間を経過した場合(S24でYES)、頻度設定部15aは位置情報取得部21に位置情報を取得させる。言い換えると、電子機器1Aはユーザの位置を測位する(S25)。
本発明の実施形態2の変形例について以下に説明する。本変形例において、乗車判定部12は、センサ部2から出力された移動状態に応じたセンサ値により乗物に対する乗車を行ったか判定し、さらに、乗物に乗車して移動している(乗車している乗物が移動している)乗車移動状態であるか否かを判定してもよい。言い換えると、乗車判定部12は、ユーザが乗物に乗車してかつ乗物が移動している乗車移動状態であるか否かをさらに判定する。乗車移動状態ではない(乗車移動状態以外の状態)とは、ユーザが乗物に乗車せず立ち止まっていたり、歩いている状態、ユーザが乗物に乗り込こもうとしている状態、および、乗物から降りようとしている状態等となる。
電子機器1・1Aの測位指示部10・10A(例えば、連続歩行検出部11、乗車判定部12、歩数計数部13、頻度切替部14・14a、頻度設定部15・15aおよび時間計測部16)およびホスト制御部20(例えば、位置情報取得部21および報知部22)は、集積回路(ICチップ)等に形成された論理回路(ハードウェア)によって実現してもよいし、CPU(Central Processing Unit)を用いてソフトウェアによって実現してもよい。
