In this project we developed a portable haptic interface for vibro-tactile feedback applications. Currently, commercial systems similar to the proposed interface have high costs with applications in specific areas, and there is no variety of these devices in Ecuador. For this reason, we propose to develop a portable vibrotactile feedback system that will allow the user to perceive movement. The illusions that were used to validate the interface are read through a micro_SD card connected to a controller, and the algorithm used transmits information through a pair of coil type actuators, generating the tactile illusion. Finally, an experiment was conducted to demonstrate its functionality, which resulted in the Funneling illusion being the one that is best perceived in the device, in addition to the fact that the participants reported perceiving a directionality in each illusion. It is expected that this system will be a support tool in urban mobility applications, due to its advantages in terms of portability, reduced weight, low cost compared to other commercial options, reproducible using the drawings and specifications of the system. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
