FREKVENCIJSKO KODOVANJE VIBROTAKTILNE POVRATNE SPREGE

This paper explains the importance of haptic feedback based on vibrotactile sensory substitution as well as the principle of its functioning. An experiment was performed with 10 subjects whose task was to learn to distinguish eight levels of vibromotor activation, which were placed on the subject’s forearms. Before the start of the experiment, after series of pilot tests, a frequency coding scheme for vibromotor activation was defined. The experiment consisted of three phases: the introduction phase, the learning phase and the test phase. After the test phase, the success of the subjects in discriminating levels of activation of vibromotors was analyzed.
