Mobile Device Detection (or 'Device Detection') is a process of identifying the type of mobile device or other device visiting a web site or other service. This commonly uses the HTTP headers transmitted by the user's browser such as User agent, though it can also be performed from other headers if present, such as IMEI or UAProf links. Mobile device detection systems typically combine a detection with the creation or retrieval of a capability profile of the device. These vary greatly in complexity, ranging from one data point to many hundreds. A device detection process answers the twin questions of "what is it?" and "what can it do?". == Background == Most desktop web browsers use HTML and display a relatively consistent web page regardless of the browser type or computer manufacturer. However, mobile browsers may use HTML, WML (WAP) or a number of other markup languages. In addition, there is a much wider diversity in screen sizes, browser types and operating systems than with desktop computers. As a result, a web site solely designed for the larger screen of a desktop computer is sometimes unlikely to appear correctly or legibly when viewed on the smaller display of a mobile phone. Developments in mobile and desktop browser technology, including the advent of HTML5 have increased the probability that a given website will display without errors on a contemporary mobile device or tablet. However, there are often functionality, responsiveness and accessibility issues connected with not adapting the user's experience appropriately for mobile, touch, or small-screen devices. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mobile device detection」の詳細全文を読む スポンサード リンク
