Enactive Torch

Equipped with the capability to deliver the sense of “sight” to the user by utilizing sensation, the Enactive Torch (ET) uses two sensors that give the device the power to detect objects at a distance of 60cm, thus delivering the information to its microcontroller to control its vibration intensity it delivers to the user. The closer an object is, the more intense the vibration becomes. This sensation allows individuals to maneuver and interact with the environment before them without the need for eyesight. The device not only delivers a vibration sensation proportional to the distance it detects an object, the ET also displays its own acceleration and the distance of the object it detects (in centimeters) to the computer through Bluetooth capabilities. The acceleration and distance are displayed in real time through Ardruino software, allowing the user of the device to receive constant information on the performance of the device.

The ET will continue to have future iterations so that the model can continue to be optimized for experimental use for the lab. Future updates and iteration plans will allow two ET to communicate to each other so that the user can receive information from two ET simultaneously. Plans to give the ET different modes will be incorporated to allow an individual to control the ET from the computer. Different modes will allow an individual on the computer to decide the vibration intensities of the two ET that another individual is holding. Modes like these will help collect valuable information for upcoming trials.

The ET was programed on Arduino software using an Arduino Pro mini as the microcontroller. Currently, the device runs on 7.4V to operate the 2 sensors, Bluetooth, the Linear Resonant Actuators (LRA), and accelerometer all housed inside the casing. The housing was designed and assembled on Solidworks and fabricated through 3D printing. The ET was 3D printed on the Ultimaker 5S using Ultimaker’s Tough PLA 3D printing material, and the current operating ET is still in the prototyping phase.
