This is the repository for PCB schematics and Arduino codes used for the "Full-Hand Electro Tactile Feedback without Obstructing Palmar Side of Hand" paper (ACM CHI2023).
For more information, please refer to our paper: http://lab.plopes.org/#boh-electro-tactile
notes:
- For PCB, the design originally assumes the use of the Bluetooth Module + Lipo battery but also works with normal Serial + power via Seeeduino XIAO's USB-C. If you go for this tethered option, ensure the battery is not connected, the power switch on the PCB is toggled ON, and the Bluetooth module is removed.
- The Kicad project for the PCB has not been tested for library compatibility, so let us know if it does not appear properly on your end, but just uploading the Gerber file should suffice for ordering the PCB.
- The Arduino code is a generic program to drive the circuit in response to Serial messages from other program instances such as Unity, Python, Processing, etc.

Questions
How big is the OpenEstim++ PCB?
It measures 41.5 × 35.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the OpenEstim++ use?
28 parts, built around the LMV358, FCX705TA, BSS87 and HV2701FG-G. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the OpenEstim++ KiCad files?
From the humancomputerintegration/BOH-Electro-Tactile repository on GitHub, at the commit this page was made from: the board is Hardware/OpenEstim++/OpenEstim++.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the OpenEstim++ design in my own project?
Its repository states no licence, so its author keeps all rights: ask humancomputerintegration before reusing the design.
