In 1846, Ernst Heinrich Weber described the linear relationship between stimulus intensity and the perceived stimulus change. Assuming that this linear relationship is independent of the stimulus intensity, Gustav Theodor Fechner characterized the sensation of a stimulus with the aid of a logarithmic relationship between intensity strength and absolute threshold. Thereby Fechner regarded as the founder of psychophysics, which includes the sensory modalities of the absolute threshold, sensory intensity, stimulus identification and attraction scaling.
We use classical and modern methods of psychophysics for the characterization of perception and possible changes in tactile and visual Stimuli.
