Based on animal head positions in a rectangular tunnel i.e. box, calc_vis_angle_box() calculates the visual angles created by lateral visual stimuli.

calc_vis_angle_box(obj_name)

Arguments

obj_name

The input viewr object; a tibble or data.frame with attribute pathviewR_steps that includes "viewr" and treatments_added.

Value

A tibble or data.frame with added variables for min_dist_pos, min_dist_neg, vis_angle_pos_rad, vis_angle_neg_rad, vis_angle_pos_deg, and vis_angle_neg_deg.

Details

cal_vis_angle_box assumes fixed gaze at the point on the either side of the tunnel that minimizes the distance to visual stimuli and thereby maximizes visual angles. All length measurements reported in meters.
