Dashboard(ダッシュボード)は、アップルのMac OS X v10.4以降に付属している、ウィジェット (Widgets) と呼ばれる小さなアプリケーションを表示するための環境である。作業中に任意の操作を行う(デフォルトではF12キーおよびマウスの第3ボタンに割り当てられている)ことによって、画面がDashboardと呼ばれる半透明のレイヤーに覆われ、ウィジェットが表示される。ウィジェットはこまごまとした作業を素早くできるような単機能のソフトウェアである。
デフォルトで添付されている、アドレスブック、カレンダー、計算機、iTunesコントローラなどのウィジェットに加え、さまざまなウィジェットを簡単に追加することができる。追加方法はDashboardの画面もしくはウィジェットをダブルクリックすることでも可能である。
ウィジェットの開発には、HTML、CSS、JavaScriptを用いる。開発が容易なため、多数のウィジェットが配布されている。アップルは、サードパーティーが開発したソフトウェアの登録を受付け、自身のウェブサイトで配布している。
Dashboardが発表される以前、Mac OS Xでは、Konfabulatorというシェアウェアのウィジェットエンジンが配布されていた。Konfabulator は、XML、CSS、JavaScriptといった技術を用いたウィジェット エンジンで、作業中のデスクトップにウィジェットを配置して使用するものだった。Dashboardそのものは、 Mac OS X v10.3から搭載されたウィンドウ一覧表示機能Exposéの拡張であり、ウィジェットは普段は隠れている点がKonfabulatorと異なる。またJavaScript制御のパッケージはSherlock 3の後続技術である。Konfabulatorの開発者はその類似性に抗議し、アップルはオリジナルであることを主張した。後にKonfabulatorは 米ヤフーに買収され、Yahoo! Widgetsとして配布されている。

A dashboard (also called dash, instrument panel, or fascia) is a control panel placed in front of the driver of an automobile, housing instrumentation and controls for operation of the vehicle.
The word originally applied to a barrier of wood or leather fixed at the front of a horse-drawn carriage or sleigh to protect the driver from mud or other debris "dashed up" (thrown up) by the horses' hooves.[1]
Items located on the dashboard at first included the steering wheel and the instrument cluster. The instrument cluster pictured to the right contains gauges such as a speedometer, tachometer, odometer and fuel gauge, and indicators such as gearshift position, seat belt warning light, parking-brake-engagement warning light[2] and an engine-malfunction light. There may also be indicators for low fuel, low oil pressure, low tire pressure and faults in the airbag (SRS) system. Heating and ventilation controls and vents, lighting controls, audio equipment and automotive navigation systems are also mounted on the dashboard.
The top of a dashboard may contain vents for the heating and air conditioning system and speakers for an audio system. A glove compartment is commonly located on the passenger's side. There may also be an ashtray and a cigarette lighter which can provide a power outlet for other low-voltage appliances.
In 1937, Chrysler, Dodge, DeSoto, and Plymouth cars came with a safety dashboard that was flat, raised above knee height, and had all the controls mounted flush.[3]
Padded dashboards were advocated in the 1930s by car safety pioneer Claire L. Straith.[4] In 1948, the Tucker became the first car with a padded dashboard.[5]
One of the safety enhancements of the 1970s was the widespread adoption of padded dashboards. The padding is commonly polyurethane foam, while the surface is commonly either polyvinyl chloride (PVC) or leather in the case of luxury models.
In the early and mid-1990s, airbags became a standard feature of steering wheels and dashboards.
In the 1940s through the 1960s, American car manufacturers and their imitators designed unusually-shaped instruments on a dashboard laden with chrome and transparent plastic, which could be less readable, but was often thought to be more stylish. Sunlight could cause a bright glare on the chrome, particularly for a convertible.
With the coming of the LED in consumer electronics, some manufacturers used instruments with digital readouts to make their cars appear more up to date, but this has faded from practice. Some cars use a head-up display to project the speed of the car onto the windscreen in imitation of fighter aircraft, but in a far less complex display.
In recent years, spurred on by the growing aftermarket use of dash kits, many automakers have taken the initiative to add more stylistic elements to their dashboards. One prominent example of this is the Chevrolet Sonic which offers both exterior (e.g., a custom graphics package) and interior cosmetic upgrades.[6] In addition to OEM dashboard trim and upgrades a number of companies offer domed polyurethane or vinyl applique dash trim accent kits or "dash kits."
Manufacturers such as BMW, Honda, Toyota and Mercedes-Benz have included fuel-economy gauges in some instrument clusters, showing fuel mileage in real time. The ammeter was the gauge of choice for monitoring the state of the charging system until the 1970s. Later it was replaced by the voltmeter. Today most family vehicles have warning lights instead of voltmeters or oil pressure gauges in their dashboard instrument clusters, though sports cars often have proper gauges for performance purposes and driver appeasement.
