Description
こと、オブジェクト上で2本の指の互いに対する向きを変化させることによってそのオブジェクトを回転させること等が含まれるが、これらに限定されるのではない。
表面上における種々の位置に配置されているとよい場合もある。実施形態の中には、タッチ・センサー410が容量性タッチ・センサーを備えているとよい場合があり、一方他の実施形態では、タッチ・センサーが抵抗性タッチ・センサーまたは他の適したタッチ・センサーを備えているとよい場合もある。更に、実施形態の中には、タッチ・センサーが多数の時間的に重複した接触を検出するように構成することができるものもあり、一方他の実施形態では、タッチ・センサーが1回ずつの接触を検出するように構成すればよい場合もある。
られているとき、タッチ・センサー410の一部を、スクロール・ホイールの特定の機能を有することにマッピングすることができる。スクロール・ホイール機能にマッピングされたこのタッチ・センサー410の一部は、次に、対応する光源420、422を点灯させて、例えば、その領域の周囲を示すことによって、領域全体を照明することによって、または他のいずれかの適したやり方で、その領域を強調することによって、輪郭を定めることができる。
ばいずれでも用いることができる。人間の肉は、いくらか導電性があり、人間は通例彼らの周囲を通じて電気接地と相応に接触している。ユーザーの指から接地への容量は、通例約1000ピコファラッドである。ユーザーの指と接触したまたは近接するタッチ・センサー410の位置の測定容量に対するこの容量の効果は、種々の方法で測定することができる。例えば、実施形態の中には、図6に示すように、センサー・エレメント510から接地までの容量を測定できる場合がある。ユーザーがセンサー・エレメントに接近しこれと接触すると、そのセンサー・エレメントの接地への容量が増大する。行および列の容量の変化に関する情報によって、接触を、作用を受けた行と影響を受けた列との間の交点に対応するセンサーの領域にマッピングすることが可能になる。
行AおよびBならびに列2および3に接触している場合、ユーザーが位置(A,2)および(B,3)に接触しているのか、または位置(A,3)および(B,2)に接触しているのか判断することが難しい場合がある。図8のコンテキストで説明するが、センサー・エレメントの各行および/または各列において接地に至る多数の接続を用いることによって、この曖昧さをある程度克服することができる。
までもない。最初に、方法90は、902において、可撓性絶縁基板の第1側に第1組のセンサー・エレメントを形成するステップを含む。904に示すように、更に具体的な一実施形態では、この第1組のセンサー・エレメントは、厚膜のような可撓性基板上に導電性インクを印刷することによって形成することができる。同様に、接触トレースを形成することができる。次に、方法900は、906において、基板の第2側に第2組のセンサー・エレメントを形成するステップを含む。908に示すように、更に具体的な一実施形態では、第2組のセンサー・エレメントは、基板の第2側に導電性インクを印刷することによって形成し、これによってセンサーを形成することができる。接触トレースも、同様に形成することができる。次に、910に示すように、湾曲したマウス表面上でセンサーを折り曲げ、次いで912において示すように、マウス表面に固定し(例えば、接着材または他の適したメカニズムによって)、接触感応コンピューター・マウスを形成する。尚、センサーの電源、コントローラー等への電気接続はいずれも、適したやり方であればいずれでも作ることができることは言うまでもない。例えば、基板は、可撓性「テール」を含むことができ、ここにトレースを印刷し、他の回路に接続するために、マウス内部に導入することができる。
が可能になる。更に、実施形態の中には、銀インクの代わりに、炭素導電性インクを用いることができる場合もある。炭素インクは、銀インクよりも安価であり、適した低抵抗を有することもできる。
ントは、例えば、1404に示すように、コンピューター・マウスの表面上に導電性インクをパッド印刷(pad printing)することによって形成することができる。パッド印刷とは、可撓性パッド上に最初にパターンを印刷し、次いで可撓性パッドを他の表面に対して押圧し、パターンをその表面に転移させるプロセスである。実施形態の中には、1406に示すように、マウス本体の内面上に導電性インクを印刷するとよい場合もあり、一方他の実施形態では、1408に示すように、マウス本体の外面上に導電性インクを印刷するとよい場合もある。マウス本体の内面上に導電性インクを印刷する場合、マウス本体は、マウス本体に接触する指がセンサーによって検出可能となる効果を得るために、十分に薄くする(例えば、約0.5mm)とするとよい。
1900で示されており、タッチ・センサーの右側における接触が、1902で示されている。次に図20を参照すると、ユーザーが「右クリック」入力を行おうとすると、ユーザーは右指でもっと多くの圧力をかけて、機械式アクチュエーターを作動させようとすることができる。この場合、右側の接触1902の接触面積が増大する。
センサーおよび抵抗性圧力センサーが共通のセンサー・アレイを共有することもできる。図21および図22は、共通の電極アレイを共有する容量性マルチタッチ・センサーおよび抵抗性圧力センサーの構造を示す。最初に図21を参照すると、2100において、行センサー・エレメント2103および列センサー・エレメント2104のアレイにおいて基板2102上にポリマー導電性厚膜を印刷することによって、センサー・アレイを形成する。2100に示すように、コネクター2106を最初に一方向(列方向として示されている)に印刷する。次に、2108に示すように、列コネクター2106上に誘電体材料2110を堆積し、次いで2112において、誘電体材料上に行コネクター2114を印刷して、センサー・アレイを完成する。最後に、2116において、センサー上に圧電シート2118を被着する。圧電シート2118は、図21では、基礎構造を図示するために、一部分解図で示されている。
[0093]
いて一定であり、容量Cも一定である(即ち、指の圧力および位置が測定中実質的に変化しなかった)という仮定が許容されるように、十分に次回時間間隔で行うとよい。これらの過程により、総インピーダンスの変化は、2回の測定を行った周波数の関数となる。このように、CおよびRは2つの測定値によって決定することができる。
n測定よりも低く、したがって、接触入力の位置に関して多少の曖昧さが生ずる可能性がある。特に、接触が少なくとも部分的に行および列センサー・エレメント双方をカバーしていないときに、その可能性がある。したがって、図24は、m×n測定方法の高い分解能にも配慮しつつ、m+n測定方法によって得られる接触至近感度の向上に備えて、容量性マルチタッチ・センサーを読み取る方法2400の一実施形態を示す流れ図を示す。方法2400は、2402において、m+n容量を測定し、その測定値から接触入力信号を判定するステップを含み、次いで2404において、この接触入力信号を以前の接触入力信号と比較し、2406において、接触入力信号間に何らかの変化が発生したか否か判断するステップを含む。変化が検出されない場合、方法2400は2402に戻り、他のm+n容量測定を行う。
または他のこのような湾曲表面とでも用いることができる。更に、本明細書において開示した実施形態は、1つの設計によって種々の異なる機能のマウスを開発するプラットフォームを製造者に提供することができることも言うまでもない。例えば、異なるボタンや他の制御部品をマウス・ハードウェアによって実装する場合、新しいマウス設計毎に、新たな型および他の器具の設計ならびに製造が、新たなハードウェア設計のために必要となることもある。対照的に、マウス本体上にタッチ・センサーおよび/または圧力センサーを含ませることによって、新たな機能をマウス本体の特定の接触領域にマッピングすることが可能となり、これによって、1つのハードウェア設計を、新たな機能を実現するために用いることが可能になる。
