Embodiment Construction

[0032] Techniques for producing contacts, contact sets, and tactile identifier marks on substrates are described below. The touch points are tactilely identifiable by the visually impaired to allow the visually impaired to tactilely identify the points.

[0033] Each contact can be individually formed in the substrate, for example by using a single punch and die pair, or by separately stamping each contact using mechanisms other than stamping, such as using a laser. By forming each contact separately, the spacing between the contacts can be changed or adjusted.

[0034] Alternatively, in a contact group comprising a plurality of contacts, the contacts of the contact group may be generated in several separate steps. For example, one or more contacts of the set of points may be produced in a first step using a first punch and die pair, and one or more additional contacts of the set of points may be produced in a second step Created using a second punch and die pair. By using ...

Abstract

The present invention describes techniques for producing contacts, sets of contacts, and tactile identifier marks on substrates that are tactilely recognizable by visually impaired persons. Each contact may be individually formed in the substrate, for example by stamping each contact separately using a single punch and die pair. By using a single punch and die pair, the size, complexity and cost of the contact imprinting mechanism can be reduced and the spacing between contacts can be varied.

Description

technical field [0001] The technical disclosure of the present invention relates to the creation of contacts, sets of contacts and tactile identifier marks on a substrate. Background technique [0002] Contacts formed on the substrate are used by the blind and other visually impaired for reading, for object recognition, and the like. The contacts are arranged in a pre-defined pattern to form tactilely recognizable characters or codes. One example of using contacts and contact groups is Braille characters. [0003] The ISO / IEC 7811-9 standard specifies the location and characteristics of tactile identifier marks on plastic cards used by visually impaired persons to distinguish their cards. [0004] In the past, the contacts on plastic cards were formed by using an embossing mechanism comprising multiple punch and die pair combinations, which increased the size of the mechanism required to form all possible characters of the 6-dot set. Additionally, the use of multiple punc...
