Haptic Feedback Perception Research

My Role:

Undergraduate Researcher Designed and prototyped an experimental setup to track multi-finger motion and developed a MATLAB application for real-time visualization and analysis of tactile exploration patterns.

Assisted in a research study on the tactile perception of electrovibration by conducting human subject experiments and processing behavioral data.

Project Info

The research explored how users perceive tactile graphics and how electrovibration can simulate texture and shape perception on touchscreens. I contributed to designing the experiment and analyzing 400 sessions to identify key exploration strategies used to recognize haptic shapes.

Impact

This project provided new insights into how humans interact with tactile surfaces and informed design principles for more intuitive haptic interfaces. The findings contributed to a published study in the International Journal of Human-Computer Studies 🔗where my work was acknowledged for experimental and analytical support.

Software

I developed a MATLAB application that collects coordinates points of hand joints in space and remaps the provided points to the experiment area. The application provides real-time visualization of exploration patterns for the use of further investigations.

Finger Motion Tracking

Tactile Perception of Electrovibration Research

The research project I assist in aims to investigate the exploration strategies of electrovibration tactile feedback and provide guidance for further haptic interface development.

In this project, I contributed to investigating primary, initial, final, most used, and least used tactile exploration strategies by analyzing 400 experiment session data.

Data Analysis

Heat maps of exploration patterns [1].

Findings

The comprehensive study was later published, and my contributions were recognized in the acknowledgment section.
