Exploring the impulsion and vibration effects of tactile patterns

This paper explores the impulsion and vibration properties of different tactile patterns (icons). These properties describe the unique movements of the pins with different values of staying raised or lowered. The tactile feedback is provided by Braille pins on a finger and is in the form of different patterns chosen for the experiments. We tested these features on the Braille display of dimension 4x2 (8 pins). The experiments were conducted to determine the selection time and error rate of impulsion and vibration characteristics. We report our preliminary results. We also discuss the related issues and propose possible future directions. Categories and Subject Descriptors H5.2. [Information interfaces and presentation]: User Interfaces, Haptic I/O. Keywords Tactile feedback, Braille cell, tactile patterns, impulsion, vibration, selection
