About: Bokode

An Entity of Type: person, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org:8891

A bokode is a type of data tag which holds much more information than a barcode over the same area. They were developed by a team led by Ramesh Raskar at the MIT Media Lab. The bokode pattern is a tiled series of Data Matrix codes. The name is a portmanteau of the words bokeh—a photographic term—and barcode. Rewritable bokodes are called bocodes. They are circular with a diameter of 3 millimetres (0.12 in). A bokode consists of an LED covered with a photomask and a lens. They are readable from different angles and from 4 metres (13 ft) away by any standard digital camera. Powered bokodes are relatively expensive because of the LED and the power it requires. However, prototypes have been developed which function passively with reflected light like a typical barcode.

  • A bokode is a type of data tag which holds much more information than a barcode over the same area. They were developed by a team led by Ramesh Raskar at the MIT Media Lab. The bokode pattern is a tiled series of Data Matrix codes. The name is a portmanteau of the words bokeh—a photographic term—and barcode. Rewritable bokodes are called bocodes. They are circular with a diameter of 3 millimetres (0.12 in). A bokode consists of an LED covered with a photomask and a lens. They are readable from different angles and from 4 metres (13 ft) away by any standard digital camera. Powered bokodes are relatively expensive because of the LED and the power it requires. However, prototypes have been developed which function passively with reflected light like a typical barcode. Bokodes convey a privacy advantage compared to radio-frequency identification (RFID) tags: bokodes can be covered up with anything opaque, whereas RFID tags must be masked by material opaque to radio frequencies, such as the sleeve provided by the New York State Department of Motor Vehicles when issuing their enhanced state IDs.

  • Un bokode est un type de code-barres bidimensionnels qui contient plusieurs centaines de fois plus d'informations qu'un code-barres simple. Ce système, dont le nom est issu d'un jeu sur les mots bokeh (un terme photographique) et code-barres, a été développé[Quand ?] par une équipe du MIT. De forme circulaire et pourvu d'un diamètre de 3 mm, le bokode est plus petit qu'un code-barres simple. Il est constitué d'une LED, recouverte d'un masque et d'une lentille. Cette nouvelle forme de code-barres est lisible sous différents angles et à 4 mètres de distance par un téléphone mobile équipé d'un capteur vidéo. Le coût de production est élevé étant donné le besoin en énergie d'une LED, mais il existe des prototypes qui reposent simplement sur la réflexion de la lumière. (fr)
  • Un bokode è un tipo di codice a barre bidimensionale a matrice (o data tag) che contiene migliaia di informazioni in più rispetto a un normale codice a barre. Il termine bokode deriva dall'unione delle parole bokeh e barcode (codice a barre).La tecnologia bokode è stata sviluppata da un gruppo del , e presentata a New Orleans nel 2009. (it)
  • Bokode(ボーコード)は、ID情報を埋め込んだ3mm未満の光源から、デジタルカメラなど焦点調節機構を備えた画像入力を用いた近〜遠距離の撮影によって情報をやりとりするもの。Bokodeという名前は、写真技術で使われている用語ボケ (写真)とバーコードから作られた造語。 (ja)
