title: iCube data visually impaired

description: Here, I report the codebook of the dataset for the variable names that are harder to interpret: <strong>group</strong>: 'early-blind', 'late-blind' or 'control' <strong>main_group</strong>: 'blind' or 'sighted' <strong>trial_type</strong>: 'memorize' or 'recall' <strong>conf</strong>: the configuration of pins locations used in the specific trial <strong>subject_orientation</strong>: oreintation of the subject in absolute coordinates while doing the test (e.g. 'north' if facing North) <strong>pin_facet_1</strong>: number of pins in facet 1 . . <strong>pin_facet_6</strong>: number of pins in facet 6 <strong>cond_facet_1</strong>: kind of face based on pin number (even or odd) . . <strong>cond_facet_6</strong>: kind of face based on pin number (even or odd) <strong>correct</strong>: correct response (i.e. 'same' or 'different') for that trial <strong>response</strong>: actual response of the subject <strong>accuracy</strong>: 1 = correct; 0 = wrong <strong>n_tocchi_trial </strong>= number (unfiltered) of active cells of the cube in the whole trial <strong>n_tocchi_facet_1 </strong>= number (unfiltered) of active cells in face #1 of the cube in the whole trial . . <strong>n_tocchi_facet_6 </strong>= number (unfiltered) of active cells in face #6 of the cube in the whole trial <strong>filt_n_tocchi_trial</strong> = number (filtered, i.e., explorative touches only) of active cells of the cube in the whole trial <strong>filt_n_tocchi_facet_1</strong> = number (filtered, i.e., explorative touches only) of active cells in face#1 of the cube in the whole trial . . <strong>filt_n_tocchi_facet_6</strong> = number (filtered, i.e., explorative touches only) of active cells in face#6 of the cube in the whole trial <strong>touch_density_trial</strong> = unfiltered touch frequency (active cells/second) in the whole trial <strong>touch_density_facet_1</strong> = unfiltered touch frequency (active cells/second) in face#1 in the whole trial . . <strong>touch_density_facet_6</strong> = unfiltered touch frequency (active cells/second) in face#6 in the whole trial <strong>filt_touch_density_trial</strong> = filtered (i.e. explorative touches only) touch frequency (active cells/second) in the whole trial <strong>filt_touch_density_facet_1</strong> = filtered touch frequency (active cells/second) in face#1 in the whole trial . . <strong>filt_touch_density_facet_6</strong> = filtered touch frequency (active cells/second) in face#6 in the whole trial <strong>duration_trial</strong> = duration of exploration in s <strong>dur_facet_1</strong> = duration of exploration in face#1 in the whole trial . . <strong>dur_facet_6</strong> = duration of exploration in face#6 in the whole trial <strong>filt_dur_facet_1</strong> = filtered (explorative touches only) duration of exploration in face#1 in the whole trial . . <strong>filt_dur_facet_6</strong> = filtered (explorative touches only) duration of exploration in face#6 in the whole trial <strong>rot_abs_total</strong> = amount of rotation in deg in the whole trial <strong>raw_mean_rot_velocity</strong> = unfiltered rotation velocity (deg/s) <strong>filtered_mean_rot_velocity</strong> = filtered (removed rotations &lt; 1deg/s) rotation velocity (deg/s) <strong>facce_esplorate_0.8s</strong> = sequence of explored faces <strong>orient_face_deg</strong> = faces orientation in spherical coordinates at the beginning of exploration of the faces reported in 'facce_esplorate_0.8s'. All cube faces are considered (i.e. list of 6 couples of coordinates for each initial timepoint of exploration of a face) <strong>orient_face_world_coord</strong> = same as above but translated to world labels (e.g. 'north', 'up', 'west', etc.) <strong>orient_face_local</strong> = same as above but translated to labels relative to the participants (e.g. 'left', 'down', 'rear'...) <strong>timepoints_facce_esplorate_0.8s</strong> = timepoints in s of the beginning of exploration of a face (see 'facce_esplorate_0.8s') <strong>mean_delta_timepoints</strong> = mean time to move from one explored face to the next (mean of 'timepoints_facce_esplorate_0.8s') <strong>std_delta_timepoints</strong> = standard deviation of 'mean_delta_timepoints' <strong>transition_local</strong> = position of explored face (see 'facce_esplorate_0.8s') relative to the participants <strong>trans_matrices</strong> = matrices expressing the probability (prop) of moving from one location to another (e.g. from 'front' to 'left') <strong>ritorni_0.8s</strong> = number of returns to already explored faces expressed as array (e.g. [0 0 0 2 0 0] = face#4 explored twice) <strong>ritorni</strong> = total number of returns to already explored faces for that trial (sum of the array coded in ‘ritorni_0.8s’)
