Description

本発明は、パーソナルコンピュータなどの電子機器の入力装置として用いられるポインティングデバイスのバッテリ残量表示方法に関する。 The present invention relates to a battery remaining amount display method for a pointing device used as an input device of an electronic apparatus such as a personal computer.

従来、特許文献１では、ポインティングデバイスと電子機器本体は双方向の通信機能を持ち、電子機器本体からポインティングデバイスに電池の残量読み取りコマンドを送り、このコマンドに対するポインティングデバイスの応答で内蔵された電池の残量を調べることができる。ポインティングデバイスと電子機器本体間の通信は送信回路、受信回路を用いて双方向通信を行っている。しかしながら、従来の方法では電子機器本体からポインティングデバイスに対して定期的に電池残量読み取りコマンドを送り、それに対するポインティングデバイスの応答から電池の残量を調べる必要があり、ポインティングデバイスを動かさなくても定期的にポインティングデバイスの回路を動作させるため、必然的にポインティングデバイスの消費電力が増え、電池が早く消耗する欠点があった。   Conventionally, in Patent Document 1, the pointing device and the electronic device main body have a bidirectional communication function, a battery remaining amount reading command is sent from the electronic device main body to the pointing device, and the built-in battery in response to the pointing device in response to this command You can check the remaining amount. Communication between the pointing device and the electronic device main body is bidirectional communication using a transmission circuit and a reception circuit. However, in the conventional method, it is necessary to periodically send a battery remaining amount reading command from the electronic device main body to the pointing device, and to check the remaining amount of the battery from the response of the pointing device to the pointing device, without moving the pointing device. Since the pointing device circuit is periodically operated, the power consumption of the pointing device inevitably increases, and the battery is consumed quickly.

又、特許文献２では、上記欠点を解決するためになされたもので、ワイヤレスポインティングデバイスはデータパケットに電池切れ予告信号を入れて送信し、そのデータパケットを受信した電子機器本体においてワイヤレスポインティングデバイスの電池切れの予告表示を行うようにしたことにより、ワイヤレスポインティングデバイスが使用されたときにのみ電池残量の検出が行なわれワイヤレスポインティングデバイスの電池の消耗を防ぐことができる。   In Patent Document 2, the wireless pointing device transmits a battery packet warning signal in a data packet, and the electronic device main body that receives the data packet transmits the wireless pointing device. By displaying the notice of running out of the battery, the remaining battery level is detected only when the wireless pointing device is used, and the battery of the wireless pointing device can be prevented from being consumed.

しかし、特許文献２を用いてもユーザがワイヤレスポインティングデバイスを使用しなければ電子機器本体への通信が行われないので電子機器本体はワイヤレスポインティングデバイスの電池残量を知ることができない問題がある。これに特許文献１を組み合わせても電池の消耗を防ぐ点での効果が得られない。   However, even if Patent Document 2 is used, if the user does not use the wireless pointing device, communication to the electronic device main body is not performed, and thus the electronic device main body cannot know the remaining battery level of the wireless pointing device. Even if Patent Document 1 is combined with this, an effect in terms of preventing battery consumption cannot be obtained.

そこで、本発明は、ワイヤレスポインティングデバイスの電池の消耗を防ぐと共に、電池残量を視認しやすくすることで電池切れによるトラブルを生じにくくすることを目的とする。   In view of the above, an object of the present invention is to prevent troubles caused by running out of battery by preventing the battery of the wireless pointing device from being consumed and making it easy to visually recognize the remaining battery level.

本発明の情報処理装置は、バッテリを内蔵したワイヤレスポインティングデバイスを有する情報処理装置であって、前記ワイヤレスポインティングデバイスは操作された時に前記バッテリの残量情報を前記情報処理装置へ通知する送信手段を有し、前記情報処理装置は所定の時間間隔で前記ワイヤレスポインティングデバイスへバッテリ残量情報を要求する信号を出力する残量管理手段を有し、前記ワイヤレスポインティングデバイスが操作されることにより前記残量情報が得られた時は、前記所定の時間間隔の開始点に変更されることを特徴とする。   The information processing apparatus according to the present invention is an information processing apparatus having a wireless pointing device with a built-in battery, and the wireless pointing device includes transmission means for notifying the information processing apparatus of remaining battery information when the wireless pointing device is operated. The information processing apparatus includes: a remaining amount management unit configured to output a signal requesting battery remaining amount information to the wireless pointing device at a predetermined time interval, and the remaining amount by operating the wireless pointing device When information is obtained, it is changed to the start point of the predetermined time interval.

本発明によれば、ワイヤレスポインティングデバイスの電池の消耗を防ぐと共に、電池残量を視認しやすくすることで電池切れによるトラブルを生じにくくすることができる。   ADVANTAGE OF THE INVENTION According to this invention, while preventing the consumption of the battery of a wireless pointing device, it can make it difficult to produce the trouble by running out of a battery by making it easy to visually recognize the battery remaining charge.

以下、図面を参照して本発明を実施するための最良の形態について詳細に説明する。図１は本発明の実施の形態の本体装置１とワイヤレスポインティングデバイス１０のブロック図である。図１を参照すると、本体装置１は例えばパーソナルコンピュータのような電子機器本体である。   The best mode for carrying out the present invention will be described below in detail with reference to the drawings. FIG. 1 is a block diagram of a main unit 1 and a wireless pointing device 10 according to an embodiment of the present invention. Referring to FIG. 1, the main device 1 is an electronic device main body such as a personal computer.

本体装置１は入力装置としてポインティングデバイス１０と無線通信を行うための送信手段５および受信手段６を備えている。無線通信としては赤外線や電波を利用することができる。残量管理手段４は本体装置１においてワイヤレスポインティングデバイス１０のバッテリ残量を管理するためのものであり、ワイヤレスポインティングデバイス１０に対してコマンドを送信してワイヤレスポインティングデバイス１０のバッテリ残量情報を得たり、ワイヤレスポインティングデバイス１０へのコマンドの送信タイミングを管理する。タイマ３はそのための時間計測手段として利用される。   The main body device 1 includes a transmission unit 5 and a reception unit 6 for performing wireless communication with the pointing device 10 as an input device. As wireless communication, infrared rays or radio waves can be used. The remaining amount management means 4 is for managing the remaining battery level of the wireless pointing device 10 in the main unit 1 and transmits a command to the wireless pointing device 10 to obtain remaining battery level information of the wireless pointing device 10. Or the transmission timing of commands to the wireless pointing device 10 is managed. The timer 3 is used as time measuring means for that purpose.

残量表示制御手段２は残量管理手段４からのバッテリ残量情報を表示部７へ視認容易に表示する。   The remaining amount display control means 2 displays the battery remaining amount information from the remaining amount management means 4 on the display unit 7 with easy visual recognition.

次にワイヤレスポインティングデバイス１０はバッテリ１３が内蔵されている。バッテリ１３は乾電池でもよいし、充電式のバッテリでもよい。ポインティングデバイス１０は本体装置１と無線通信を行うための送信手段１１および受信手段１２を備えている。   Next, the wireless pointing device 10 incorporates a battery 13. The battery 13 may be a dry battery or a rechargeable battery. The pointing device 10 includes a transmission unit 11 and a reception unit 12 for performing wireless communication with the main body device 1.

残量検出手段１４はバッテリ１３の残量を検出可能である。検出精度としては所定のレベルで検出可能でもよい。   The remaining amount detecting means 14 can detect the remaining amount of the battery 13. The detection accuracy may be detectable at a predetermined level.

残量情報生成手段１５は残量検出手段１４にて検出された残量情報を本体装置１とのコマンドに埋め込むことが可能である。   The remaining amount information generating unit 15 can embed the remaining amount information detected by the remaining amount detecting unit 14 in a command with the main device 1.

次に動作について説明する。本実施の形態の動作について図２から３を参照して説明する。図２は本発明の実施の形態におけるバッテリ残量検出処理のフローチャートである。   Next, the operation will be described. The operation of the present embodiment will be described with reference to FIGS. FIG. 2 is a flowchart of the remaining battery level detection process in the embodiment of the present invention.

まず、本体装置１に電源を入れると本体電源ＯＮと判定され（Ｓ１）、バッテリ残量管理手段本体装置１はワイヤレスポインティングデバイス１０に対してバッテリ残量を通知させるためのコマンドを送信し、ワイヤレスポインティングデバイス１０よりバッテリ残量を通知するためのコマンドを受信する（Ｓ２）。   First, when the main unit 1 is turned on, it is determined that the main unit power is ON (S1), and the battery remaining amount management means The main unit 1 transmits a command for notifying the wireless pointing device 10 of the remaining amount of battery, and wireless A command for notifying the remaining battery level is received from the pointing device 10 (S2).

次に本体装置１のタイマ３に所定の初期値を設定する。初期値の値はワイヤレスポインティングデバイス１０の残量を検出するのに効果的でかつバッテリ１３の残量をできるだけ消耗させない値が好ましい。ここでユーザがワイヤレスポインティングデバイス１０を操作することにより残量検出手段１４によりバッテリ１３の残量検出がされると残量コマンド生成手段１５により残量コマンドが生成され、送信手段１１よりワイヤレスポインティングデバイス１０の通常使用の通信に埋め込まれて残量コマンドが本体装置１へ送信される。   Next, a predetermined initial value is set in the timer 3 of the main unit 1. The initial value is preferably a value that is effective for detecting the remaining amount of the wireless pointing device 10 and that does not consume the remaining amount of the battery 13 as much as possible. Here, when the remaining amount of the battery 13 is detected by the remaining amount detecting unit 14 by the user operating the wireless pointing device 10, a remaining amount command is generated by the remaining amount command generating unit 15, and the wireless pointing device is transmitted from the transmitting unit 11. The remaining amount command is transmitted to the main device 1 by being embedded in 10 normal use communications.

本体装置１の受信手段６により残量コマンドが受信されると（Ｓ４）、本体装置１のタイマは再度初期値が設定される（Ｓ５）ので、本体装置１からワイヤレスポインティングデバイス１０への残量確認のためのアクセスタイミングが遅延され、バッテリ１３の消耗が抑えられる。ワイヤレスポインティングデバイス１０への操作がなく、初期値の設定がされたタイマ３の時間が経過すると（Ｓ６）、残量管理手段４は残量確認のためのコマンドを送信手段５よりワイヤレスポインティングデバイス１０へ送信する。   When the remaining amount command is received by the receiving means 6 of the main unit 1 (S4), the initial value of the timer of the main unit 1 is set again (S5), so the remaining amount from the main unit 1 to the wireless pointing device 10 The access timing for confirmation is delayed, and consumption of the battery 13 is suppressed. When there is no operation on the wireless pointing device 10 and the time of the timer 3 for which the initial value is set has elapsed (S6), the remaining amount management means 4 sends a command for checking the remaining amount from the transmitting means 5 to the wireless pointing device 10 Send to.

図３は本発明の実施の形態における本体装置の表示装置による表示例である。本体装置１はディスプレイ２０と装置本体２３を備えている。残量管理手段４により得られたバッテリ１３の残量情報により、残量表示制御手段２により画面上のマウスカーソル２１の領域内に残量が視認可能なバッテリ残量領域２２として表示される。表示の仕方としては残量を視認するために効果的な色や点滅にて表示されることが望ましい。例えば前記画面表示はマウスカーソルの領域内における色分けがバッテリの残量の比率に応じて色分けされてもよい。

FIG. 3 shows an example of display by the display device of the main unit in the embodiment of the present invention. The main device 1 includes a display 20 and a device main body 23. Based on the remaining amount information of the battery 13 obtained by the remaining amount management means 4, the remaining amount display control means 2 displays the remaining amount in the area of the mouse cursor 21 on the screen as a battery remaining area 22 where the remaining amount can be visually recognized. As a way of display, it is desirable to display with an effective color or blinking in order to visually recognize the remaining amount. For example, the screen display may be color-coded in the area of the mouse cursor according to the ratio of the remaining battery level.
