Task.create_fixation(shape='complex', color='black', size=0.2)[source]

  • shape: {‘dot’, ‘complex’} (default: ‘complex’)
    Choose the type of fixation:
    • dot: a simple fixation dot (.2 deg visual angle)
    • complex: the ‘best’ fixation shape by Thaler et al., 2012 which looks like a combination of s bulls eye and cross hair (outer diameter: .6 deg, inner diameter: .2 deg). Note that it is constructed by superimposing two rectangles on a disk, so if non-uniform background will not be visible.
