- the control unit 103 may disable each planar antenna 105 within a predetermined range (for example, within a radius of 2 cm) from the touched position. Therefore, if the planar antenna 105 has been used for downlink reception, it is possible to reduce the noise of the received signal by not using the planar antenna 105 .
- planar antenna 105 when used for uplink transmission, wasteful power consumption can be reduced by not using the planar antenna 105 . This is because millimeter waves and terahertz waves are attenuated more when they pass through an object such as a finger on the screen than radio waves with lower frequencies.

- a plurality of planar antennas 105 may be provided at the first density in the central region of the screen.
- a plurality of planar antennas may be provided at a second density higher than the front first density.

- the control unit 103 may cause the display element 102 to emit light of at least one of blue and red for a short period of time (short-pulse drive), and the optical sensor 201 may detect whether an object such as a finger is present. Thereby, for example, a touch can be detected even in a relatively dark area of the display screen. This is because the human eye is sensitive (high) to green and relatively insensitive (low) to blue and red.
- control unit 103 may increase the light emission intensity (luminance, brightness) of the display element 102 at the touched position. As a result, for example, it is possible to improve the accuracy of detection by the optical sensor 201 while reducing glare to the user due to the light emitted from the display element 102 being blocked by an object such as a finger. In this case, the control unit 103 may increase the intensity of at least one of blue and red light emitted from the display element 102 at the touched position. As a result, for example, it is possible to reduce glare that the user feels when touch with a finger or the like is stopped.
- the display element 102 may have an LED that emits infrared light (IR-LED) in addition to the three LEDs of red, green, and blue. Then, the control unit 103 may cause the IR-LED to emit light as appropriate.

Therefore, when a dedicated pen (touch pen) that generates a magnetic field, a finger, or the like is brought close to the screen of touch panel 100, the antenna characteristics (particularly impedance characteristics) of planar antenna 105 change due to electromagnetic induction.
- the control unit 203 detects contact with the touch panel 100 based on changes in antenna characteristics when the planar antenna 105 is contacted. In this case, the control unit 203 may determine that the planar antenna 105 has been touched when the antenna characteristics of the planar antenna 105 change in a predetermined pattern. Further, the control unit 203 may determine the position corresponding to the contacted planar antenna 105 among the plurality of planar antennas 105 as the contact position on the screen of the touch panel 100 .

Abstract
Description
<システム構成>
図1は、実施形態に係る無線通信システム1の構成例を示す図である。図1において、無線通信システム1は、情報処理装置10、及び基地局20を有する。なお、情報処理装置10、及び基地局20の数は図1の例に限定されない。
<構成>
次に、図2から図6を参照し、第1実施形態に係る情報処理装置10のタッチパネル100構成の一例について説明する。図2は、第1実施形態に係るタッチパネル100の構成の一例を示す図である。図3及び図4は、第1実施形態に係る表示素子102及び平面アンテナ105の配置の一例を示す図である。図5及び図6は、第1実施形態に係るタッチセンサ106の一例を示す図である。
<処理>
制御部103は、アプリケーションプログラム毎に、タッチされる頻度が高い位置に対応する平面アンテナ105を予め無効化してもよい。この場合、制御部103は、画面上の各領域に対して、特定のアプリケーションプログラムによりタッチパネル100の画面に表示が行われている際にタッチされた頻度を記録してもよい。そして、制御部103は、当該頻度(例えば、所定時間当たりの回数)が閾値以上である領域の平面アンテナ105を不使用とし、当該領域以外の領域に対応する平面アンテナ105を用いて、受信及び送信の少なくとも一方を行ってもよい。これにより、図7のようにタッチされてから無効化する場合よりもさらにノイズの低減、及び省エネルギーを実現できる。
制御部103は、ボタン等のタッチされる可能性が高い位置に対応する平面アンテナ105を予め無効化してもよい。この場合、制御部103は、押下用のGUI(Graphical User Interface)部品が表示されている画面上の領域以外の領域に対応する平面アンテナを用いて、受信及び送信の少なくとも一方を行ってもよい。これにより、図7のようにタッチされてから無効化する場合よりもさらにノイズの低減、及び省エネルギーを実現できる。
タッチパネル100の画面上の各位置に対応して、平面アンテナ105の設置される密度が異なるようにしてもよい。この場合、例えば、画面における中心部の領域では、第1密度で複数の平面アンテナ105を設けてもよい。そして、画面における縁部の領域では、前第1密度よりも高い第2密度で複数の平面アンテナを設けてもよい。これにより、例えば、タッチパネル100の画面で均一な密度で平面アンテナ105を設置する場合と比較して、指等により電波が遮蔽される頻度が低減されるため、ノイズの低減、及び省エネルギーを実現できる。これは、画面の端部に近いほど、ユーザにタッチされる頻度が比較的低いと考えられるためである。
上述した例では、投影型静電容量方式、または電磁誘導方式のタッチセンサ106を用いる例について説明した。以下では、タッチセンサとして光センサを用いる例について説明する。なお、以下では、第2実施形態において第1実施形態と異なる部分のうち主なものについて説明する。なお、第1実施形態の各部と第2実施形態の各部は、適宜組み合わせて用いることができる。この場合、例えば、タッチパネル100の画面の領域のうち一部の領域については、投影型静電容量方式、または電磁誘導方式のタッチセンサ106を用いる構成としてもよい。そして、タッチパネル100の画面の領域のうち他の領域については、光センサによるタッチセンサを用いる構成としてもよい。
上述した例では、平面アンテナ105とは別体のタッチセンサ106または光センサ201を用いる例について説明した。以下では、平面アンテナ105をタッチセンサの少なくとも一部として用いる例について説明する。なお、以下では、第3実施形態において第1実施形態と異なる部分のうち主なものについて説明する。なお、第3実施形態の各部と、第1実施形態の各部及び第2実施形態の各部とは、適宜組み合わせて用いることができる。この場合、例えば、タッチパネル100の画面の領域のうち一部の領域については、第1実施形態のタッチセンサ106及び第2実施形態の光センサ201の少なくとも一方を用いる構成としてもよい。そして、タッチパネル100の画面の領域のうち他の領域については、平面アンテナ105によるタッチセンサを用いる構成としてもよい。
例えば、基地局を衛星等に載せることにより、基地局の設置コストを低減し、離島、僻地、飛行機内、船内でもブロードバンド通信を行えるようにする場合について検討する。ミリ波及びテラヘルツ波のような高周波数帯の電波を用いる場合、衛星等に搭載された遠距離の基地局と通信するためには、端末においてアンテナの総面積を増加(アンテナモジュールの大型化)させる必要がある。
図12は、情報処理装置10の少なくとも一部(例えば、制御部103)をコンピュータとプログラムで実現する場合のコンピュータ1000の構成の一例を示す図である。図12の例では、コンピュータ1000は、プロセッサ1001、メモリ1002、通信インターフェイス1003を含む。これら各部は、バス等により接続されてもよい。メモリ1002は、プログラム1004の少なくとも一部を格納する。通信インターフェイス1003は、他のネットワーク要素との通信に必要なインターフェイスを含む。
