Tactile feedback from shoulder strap directly delivered to the shoulder of the user.
The use of vibrating motors in the shoulder straps enables the use of a tactile feedback directly on the body of the user that will know when it’s time to turn or change direction to get to the final destination. This kind of feedback won’t interfere with sight and hearing, senses that should be used to enjoy the surroundings. The backpack is connected to an app that manages the map and GPS signal to generate the indications at the right moment.
ESP32 for Hardware, Mapbox for software.
The prototype we developed was used to test the effectiveness of the product and to point out possible problems that wouldn’t expect before. The testing phase allowed us to find an optimal position for the vibrating motors and to manage the complexity of the different signals, giving the clearest signal to the user.
For the realization of the prototype we used one ESP32 board connected to four vibrating motors through cables and a power bank to provide energy to the system. The motors were embedded in the shoulder straps. The native app managing the communication is based on Mapbox SDK, it establishes a BLE connection with the ESP32 sending strings with the specific instructions to activate the vibration.
