摘要：
For gaze-controlled text size control of a display, the invention proposes to probe, sample and record a user's horizontal gaze Signal; to subject the gaze Signal to a subband filterbank or wavelet transform; to detect line delimiters in the gaze Signal; to derive a reading speed; to determine, as a number of saccades per text line the number of locations where the gaze Signal has sudden high slope portions surrounded on both sides by portions of markedly smaller slope; to detect, based on the reading speed and the number of saccades, a too small font size Status or a too big font size Status; and to initiate a corresponding font size change. Parts of this method can be used for gaze-based measuring of text reading speed and for gaze-based measuring of number of saccades.
