“Tikk, tikk… tekk!” The Special Sound Of Measure

No more approximations, not even if you’re blind. A reassuring sound of “Tikk, tikk… tekk”, two fingers and some Braille embossed cylinders, mix them up and you got yourself the Tikk-Tekk Rainbow! It’s a low-cost universal measuring tool that uses a string (ranging from 1cm to 100 cm) wrapped within the casing, and is extended between the finger tips. Kinda like how you use your hands to gesture an estimated distance; only Tikk-Tekk gives you the exact numbers.

    What do blind people measure? (not being a d bag, i honestly dont know)

  • Good question John.

    In daily life, we use numbers and words to describe the length of a line, the dimension of an object and the volume of a space. The height of my table is 70cm. The diameter of a basketball is 9.4 inches. The width of my bed is 1.35m.

    This is so abstract that we, in order to gain a better visualization, sometimes need to compare it with objects that we are familiar with, and even use hand gestures. For example, the size of a CD is like that of a hamburger (use your two hands to make a hamburger size and show it to the person you’re talking to). The trunk of my backyard tree is just the size of my hug.

    Now, let’s think about the blind people. How will they describe dimensions and sizes with us? How will they understand if you told them the numbers? There seems to be a hidden gap of communcation between us and them right here.

    And I think one solution is to convert the hand gestures (the distance between the two hands) of a blind people into numbers that we can read. Here Tikk-Tekk Rainbow also becomes a reference for the blind that they could understand the length of 5cm/10cm/23cm… just by moving their hands.

    OK, excuse my blah blah and back to the question. What exactly will a blind people measure? Give him a Tikk-Tekk Rainbow and let him show you:-)

    it’s funny cause the thumb is the less used finger by blind people to read braille…

    • There are 3 feedbacks from the Tikk-Tekk Rainbow where people can get to know the measuring result.

      1. Tactile (little shocks, like that of a mouse click). A “Tikk” at every 1cm and a “Tekk” at every 5cm.
      2. Tactile. Embossed braille dots for the visually impared.
      3. Visual. Silk-printed digits for people who can see.

      And here the “Tikk-Tekk” feedback is the primary and more convenient way for the blind to get the result.

    Where was the ‘design for the blind competition’ Yanko is getting all this dribble from? There seems to be a heck of a lot lately.

  • There seems no “design for the blind competition” as yet. This project was awarded an IDEA Bronze.

    i think this would be good if it expressed the measurement by pitch. im sure blind people got good ears so have it so small measurements are high pitch and long are low pitch etc
