AIRBORNE ULTRASONIC TACTILE DISPLAY BRAIN-COMPUTER INTERFACE PARADIGM
This paper explores a new way to interact with computers using touchless technology that sends vibrations through the air to the skin. This could help people with disabilities communicate more easily.

- 1 The study introduces a new touchless method for brain-computer interfaces using ultrasonic waves.
- 2 This method is more hygienic and could prevent skin issues for users.
- 3 Results show that this new method can be as effective as traditional tactile methods.
Introduction
The introduction discusses the limitations of traditional BCIs that rely on visual or auditory stimuli and presents the AUTD as a hygienic alternative for tactile stimulation, particularly beneficial for patients in locked-in states.
Materials and Methods
Thirteen male volunteers participated in the study, which adhered to ethical guidelines. The AUTD generated tactile sensations through focused ultrasound, while a comparison was made with classical vibrotactile transducers.
Results
The results showed that the AUTD-based BCI achieved mean accuracies of 63.8% and 69.4% in different trials, with maximum accuracies of 78.3% and 84.6% compared to the classical method.
