FOUNDANCE USERNAME: makerhacks24 What it Does Our project, BrailleHelper, uses a combination of circuitry and mechanical design to translate visual pictures into analog impulses. By providing tactile feedback in the form of visual information, this device helps blind people perceive and comprehend their surroundings more clearly.

How We Built It BrailleHelper was constructed by combining multiple essential elements:

Mechanical Design: Using movable pins, we created a tactile interface that represents visual data in a manner akin to Braille. Image processing: A camera takes pictures of the surroundings, then employs algorithms to extract relevant features. Circuitry: We created a circuit that converts the processed picture data into analog signals, which power the tactile feedback-producing mechanical interface. Challenges We Ran Into

Image Processing Accuracy: It was difficult to accurately convert visual data into haptic information, particularly in different lighting settings. Mechanical Precision: A great deal of testing and iteration went into designing a mechanical interface that could consistently translate signals into exact tactile patterns. Integration Problems: We had to thoroughly debug and optimize our design in order to integrate the mechanical, electrical, and software components into a coherent system. Achievements We're Proud Of: Developed a Functional Prototype: We were able to create a prototype that successfully converts haptic feedback from visual information. User Testing: To begin with, we tested our friend who is blind.
