Typhlological models are three-dimensional physical representations designed to be explored through touch<\/strong>, designed especially for people with visual impairments.\u00a0<\/p>

The term \u201ctyphlological\u201d comes from Greek typhlos<\/em> (blind) and logos<\/em> (study), and is used to refer to everything related to education and accessibility for people with blindness or low vision. Thus, a typhlological model is not just a miniature model: It is a form of multisensory communication<\/strong> which allows you to experience buildings, landscapes or heritage elements through touch.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Today, talking about accessibility is no longer just a matter of legal compliance, but of justice and universal design<\/a>.\u00a0<\/p>

The models designed for the visually impaired allow blind or visually impaired people<\/strong> understand the form, structure and spatial distribution<\/strong> of a place or architectural element. This can make a big difference to your experience in a museum, an exhibition, or even a classroom.<\/p>

Furthermore, their use benefits all audiences: children, the elderly, or any curious visitor. By incorporating touch as the primary means of exploration, these models stimulate active learning, improve information retention, and enrich the cultural experience.\u00a0<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Blindfolded models are not only suitable for museums or cultural centers<\/a>. Their versatility allows them to be integrated into multiple contexts where tactile knowledge improves the understanding of the environment or a technical process.<\/p>

One of the most common places where they are used is in inclusive museums, which aim to guarantee a complete experience for all visitors. In these cases, the models allow visitors to explore monuments, historical buildings, and cultural landscapes through touch, facilitating a richer spatial understanding than that obtained only from verbal descriptions or images.<\/strong><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The industry<\/span> It is also beginning to explore its potential. Companies in the energy, rail, and civil engineering sectors are using blindfolded models to explain complex infrastructures, machinery or production processes<\/strong> in guided tours or open days.\u00a0<\/p>

Finally, in urban or heritage spaces,<\/span> These models serve as tactile orientation points<\/strong> suitable for all audiences<\/strong>.

The furniture on which a model is displayed must also meet inclusion criteria<\/strong>, because it is an active part of the user experience. A poor installation can turn a good design into yet another barrier.<\/p>

One of the most important aspects is the stand height<\/strong>, which must allow exploration for both standing and wheelchair users. European and museum guidelines recommend a height between 75 and 90 centimeters from the ground<\/strong>, with a possible tilt of between 15\u00b0 and 30\u00b0 to facilitate tactile reading without straining the user's posture. This tilt not only improves access but also helps maintain a clear orientation of the model for any user.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

In addition to height, it is essential that the furniture allows for comfortable frontal approach<\/strong>, with enough free space for the user to stand in front of the model without restrictions. This implies leaving an area of at least 70 cm deep and 80 cm wide<\/strong>, which makes it easier for people with reduced mobility or with a guide cane to use it.<\/p>

Regarding the materials, they must be safe, durable and pleasant to the touch<\/strong>. Sharp edges, unstable surfaces, or flimsy structures should be avoided. It is also recommended that the furniture incorporate supplementary informational elements, such as Braille panels, embossed pictograms, or sensor-activated audio systems<\/strong>. The entire system must be designed to offer an accessible, autonomous, and comfortable experience, from the first touch to the end of the touch journey.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

The complexity of creating models for the blind: a job for specialists<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Developing a model for the blind is a challenge that combines technical design, creativity and in-depth knowledge of accessibility<\/strong>. It is not enough to reproduce an object or space in miniature: forms must be simplified without losing essential information, durable and safe materials must be chosen, and ergonomic criteria must be applied so that anyone can explore it comfortably.<\/p>

For this reason, having a specialized team makes all the difference. At IA Manufacturing, we put our experience at the service of projects that seek to pave the way for inclusion.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
