We'd love to get your feedback and know if you want to explore this research further.
Feedback on foot pedals affects the user's ability to control dynamic systems. However, the interplay between objective performance and user's perceived control has not been formally investigated for foot pedals. Thus, we evaluated this interplay for 4 pedal configurations: rigid and compliant pedals with and without vibrotactile feedback synchronized with user action. We conducted a within-subjects study with 12 participants, consisting of (1) a one-dimensional following task, (2) a driving task in VR to measure user performance, and (3) qualitative interviews for understanding users' subjective control. The objective performance metrics showed no significant differences between the pedal configurations. In contrast, analysis of the interviews revealed that motion-coupled vibrotactile feedback increases the participants' perceived control. These results offer possibilities for designing customized pedal feedback without compromising performance. This research emphasizes evaluating objective performance as well as perceived control while assessing control strategies for existing and novel interfaces.
Download the code from the GitHub website or clone repo using your favorite git-client software or with the following command:
git clone https://github.com/sensint/HapticGasPedal.git- To run the processing script (Targetting_Task.pde) as is, please add all the trajectories in the same folder as the processing file.
- Assign the right port for the serial communication.
- Run the script
We provide the firmware for two build systems - Teensyduino (based on Arduino IDE) and PlatformIO.
The firmware was tested with the following microcontrollers:
- Teensy 4.1
The easiest way to get up and running with the firmware is Teensyduino.
Download and install the Teensyduino software for your operating system. All needed libraries are included in the basic installation.
This project is based on the Teensy microcontroller and the PT8211 Audio Kit.
