The name Ganto comes from Esperanto language and means glove, but the truth is that is a semi-glove.

The main function is to transmit a wide range of haptic information in a accurate way. The aesthetics are based in the Stingray shape due to his nice form adaptability and conditioned by the funcionality and ergonomy. 

We decided to use the top palm of the hand because there is the most sensible accesible region so you can use the bottom side for daily tasks.

Engineering process

First prototype, end-2018


After a long iteration of prototypes and tests where we were optimizing the mechanical actuations to the skin in a accurate way we face out problems with the electronics size and the flexiblity and adaptation to the skin thus ergonomy.

For this reason I worked hard in the prototype manufacture process, upgrading my own 3D Printer with a Flexible Filament system and Organic CAD modelling. We need also this materials because is nice when dispelling the vibration noise produced by the actuators


The results is a one finger attach system that improves surface adhesion and gives comfortability. Like a watch, Ganto attachts to your wrist in a quick way.

In the bottom we found an array of 5 haptic actuators that transmits translated information from an external source like an smartphone. A touchpad is provided for interact with the haptic layer, the device or the external device.



For testing this device I designed GantoP, that is a prototype and a 3D printable version, it means that is optimized for manufacture by FDM technologies, layer by layer, with flexible materials, without supports and an optimized custom infill that works damping actuators noise with the main idea of share with the maker community.


And how works? Well, because during the design process we tested the prototypes with the best touch-capability users , like blind or deaf people , we realised that the urgent need they have is in mobility. 71% of Blind people in Spain don’t go out their houses if they don’t know the route, and voice GPS are not working well because a blind person have problems uderstanding orientation signals like : ” Go left in 150m ” ¿How much it is 50m?! With haptics we can “draw” the way and the distances, doing it better understable.

GantoP is 15% bigger and it has a custom PCB, designed by my partner Rafael Moreno, that allows us testing.

Here you can see a Test with a blind user.

Ganto is still work in progress and will be improved in the future together with the design of Aro .



Ganto Logotype


Ganto is the result of a long process of designing and researching about Haptics and human skin mechanoreceptors where I mixed all my design, scientific and engineer knowledge. Ganto is a Haptic Interface that sends high resolution information to the hand throughout touch.
