The bokode pattern is a tiled series of Data Matrix codes. The name is a portmanteau of the words bokeh —a photographic term for defocus —and barcode. Rewritable bokodes are called bocodes.

This bokeh-code or Bokode is a barcode design with a simple lenslet over the pattern. We show that an off-the-shelf camera can capture Bokode features of 2.5 microns from a distance of over 4 meters.

Feb 5, 2025 · In this in-depth guide, we’re going to look at what makes Bokode such an exciting development, identifying the specifications that allow them to store vast data caches, and how they can be used in the future.

Jul 27, 2009 · The Bokode system uses an out-of-focus camera—which allows the angle-encoded information to emerge from the resulting blurred spot— to record the encoded information from the tiny tag. Bokodes have several advantages.

Jul 24, 2009 · The name Bokode comes from the Japanese photography term bokeh, which refers to the round blob produced in an out-of-focus image of a light source. The Bokode system uses an out-of-focus camera -- which allows the angle-encoded information to emerge from the resulting blurred spot -- to record the encoded information from the tiny tag.

The new Bokode can store 1000x what a regular barcode can hold, and uses affordable technology that could change the way barcodes are used forever.

Bokode: Imperceptible Visual Tags for Camera-Based Interaction from a Distance was active from January 2008 to January 2012 With over a billion people carrying camera-phones worldwide, we have a new opportunity to upgrade the classic bar code to encourage a flexible interface between the machine world and the human world.

Bokode is an innovative optical code that offers a high density of information. Unlike conventional barcodes or QR codes, which encode information in horizontal and vertical lines, Bokode uses a different method: the information is encoded as a function of the reading angle.

We present a novel optical barcode design, called the Bokode (Figure 1), which may be read by a camera at relatively large distances.

Jul 25, 2009 · The Camera Culture group presents Bokodes, tiny imperceptible barcodes that can be read by a standard camera positioned up to four meters away to decode id...
