Smart Braille Block

Smart Braille Block (Tactile Walking Surface Indicator) is a system that provides important walking information to the visually impaired.
Provide essential information such as doors and crosswalks to the visually impaired by voice.
We provide convenience by connecting disconnected Braille blocks with supermarket paint and
using flat blocks to reduce the inconvenience of transportation for wheelchairs and strollers.

  • When walking for the visually impaired Provide essential information

    Essential information such as “entrance,” “crosswalk,” “elevator,” and “crossroads” are provided by voice through a smart cane or smart shoe that recognizes smart braille blocks coated with more than 10 types of special substances.

  • Connecting disconnected braille blocks

    Just by applying smart paint, a safe route can be displayed by connecting disconnected dot-shaped blocks, and does not cause additional inconvenience to citizens other than the visually impaired.

  • Introducing flat blocks that eliminate irregularities that cause conflicts of interest

    The irregularities of the Braille blocks cause inconvenience to the passage of (electric) wheelchairs, carts, and strollers, and this is acting as a major obstacle to the introduction and expansion of Braille blocks. This problem can be solved by introducing flat blocks.

Key Features

  • Provides essential audio information
    when walking for the visually impaired
  • Display a path by connecting dot type blocks
    with smart paint

    (You can choose colors such as yellow or achromatic)

  • Introducing flat blocks
    that eliminate irregularities

Special substances in smart paint

Physical Taggant

Taggant powder produced according to the type and mix of rare earths used and nano-processing method is
It has very unique chemical and optical properties and is called a chemical fingerprint.

21번 스칸듐, 39번 이트륨과 린타넘족 57번 ~ 71번 까지 총 17개의 원소를 일반적으로 희토류라 한다.
그러나 이름과 달리 희귀하지 않고 대부분이 매우 풍부하다고 함.

  • physical taggant

    A powder-type marker added to materials to distinguish counterfeit products, identify information for tracking purposes, and detect mixture homogeneity.

  • RF taggant

    Radiofrequency microchips used for automatic identification and data capture

  • SW Taggant

    Cryptographic signature added to SW to enable original identification and integrity of the program

Characteristics of Physical Taggant

When a light source in a specific wavelength range is irradiated with high energy (laser) on any material, the material that scatters (reflects) light in the same wavelength range It is divided into materials that scatter (reflect) light in a wavelength range that is higher (Stokes shift) or lower (anti-Stokes shift) than the original light source. Physical Taggant powder is manufactured from rare earth metals that cause the latter phenomenon to have specific optical properties as raw materials.

Application of Physical Taggant

  • Explosive Tracking

    Analyze explosive remnants to track the type and manufacturer of explosives

  • Life Sciences & Diagnostic Medicine

    Diagnostic materials, reagents, analysis, monitoring, etc.

  • Anti-counterfeiting

    Identify counterfeit products by identifying taggants contained in QR codes, fibers, plastics, etc.

  • aerospace military

    Identification of enemies through special optical coating and on-site diagnosis, TTL (Tag-Track-Locate) biological and chemical warfare detection analysis, non-ignition tracking, etc.

  • Anti-counterfeiting QR code
  • Fuel additives such as petroleum
  • security ink, paint
  • Anti-counterfeiting
    Plastic resin, fiber, etc.
