Student Lara designs a tactile lollipop concept so blind women can read pregnancy tests

A design student named Lara has developed a concept for a small lollipop-shaped object that would give a result perceptible by the tongue, according to catracalivre.com.br. The idea came from a blind friend, who told her that the hardest part of a home pregnancy test is not using it but learning the result without asking someone to read the lines catracalivre.com.brcatracalivre.com.brcatracalivre.com.brOpen source ↗.

Lara spoke with women who use screen readers and objects with tactile markings. Their experiences with physical tests varied: some wanted privacy, others needed accessible instructions from the moment the package is opened. She noted which steps depend on vision: identifying the correct side, timing the wait and interpreting the result.

Tactile interface, not a test

The design has two flat sides with reliefs meant to be told apart by the tongue. Lara tested only inert texture models, with no diagnostic substances. In a trial with clean pieces, a colleague confused two versions of the relief, so a difference that is clear to the fingers is not necessarily perceived the same way in the mouth.

The object does not detect anything. Most home tests use urine to detect a hormone associated with pregnancy, and Lara had imagined saliva only because of the shape catracalivre.com.brcatracalivre.com.brcatracalivre.com.brOpen source ↗. She states that the work would need a suitable marker, detection limits, sensitivity and specificity studies, and a reliable way to turn a chemical result into texture.

Open questions

A teacher suggested separating the reading problem from the biological sample problem. Lara is now considering tactile or audio outputs for tests that are already validated. Privacy is a concern, since loud audio could reveal the result to people nearby, so the choice would be left to the user and checked with comprehension tests.

Participants asked how they would know that a test had failed and whether a relief would change with moisture or saliva. Lara removed the phrase "independent result" from her poster and replaced it with "concept for exploring accessible forms of reading". She also began comparing tactile proposals, private audio and instructions compatible with screen readers.

She presented the model with a list of scientific and regulatory steps still required. No one received a product for home use, and the textures show a possible interface, not an exam that can confirm or exclude pregnancy catracalivre.com.brcatracalivre.com.brcatracalivre.com.brOpen source ↗. During the presentation, an instruction that was hard to locate was corrected on the spot.
