Based on animal head positions in a V-shaped tunnel tunnel,
calc_vis_angle_V()
calculates the visual angles created by lateral
visual stimuli.
calc_vis_angle_V(obj_name, simplify_output = FALSE)
obj_name | The input viewr object; a tibble or data.frame with attribute
|
---|---|
simplify_output | If TRUE, the returned object includes the minimum distance between the subject and the lateral walls as well as the visual angles (in degrees) to those points on the walls. If FALSE, the returned object includes all variables internal to the calculation. |
A tibble or data.frame with added variables for

vis_angle_neg_deg
cal_vis_angle_V
assumes the subject's gaze is fixed at the
point on the either side of the tunnel that minimizes the distance to
visual stimuli and therefore maximizes visual angles. All length
measurements are reported in meters.
