datasets from humans performing a navigation task in VR:
dataset1.mat: data from experiments in which target locations were discrete and target distances were long (~30m)
dataset2.mat: data from experiments in which target locations were continuous and target distances were short (~6m). Each trial corresponds to one of four experimental conditions (2 sensory reliabilities x 2 max velocities)
dataset3.mat: data from experiments in which target locations were continuous and target distances were short (~6m). Sensory reliability and max velocity were fixed.
Data structure:
Each dataset is formatted as a matlab array of structures. Each element corresponds to one subject. Each subject contains the following fields:
resp: An array of stopping locations encoded in polar co-ordinates -- r is the distance of the participant from the origin at the end of the trial, theta is the angle relative to straight ahead at the end of the trial. The participant is located at the origin at the beginning of each trial.
targ: An array of target locations encoded in polar co-ordinates -- r is the distance of the target from the origin, and theta is the target angle relative to straight ahead.
traj: A cell array of movement trajectories in cartesian co-ordinates. Each cell contains the trajectory from one trial -- xt and yt denote the x and y co-ordinates of the trajectory i.e. participant's position as a function of time t
vel: A cell array of movement velocities. Each cell contains the velocity from one trial -- vt and wt denote the forward velocity and angular velocity, respectively, as a function of time t
prs: An array of trial-specific parameters. floordensity denotes sensory reliability and maxvelocity denotes maximum movement speed. rendering is a flag generated online during the experiment: 1 denotes succeessful rendering of the stiumulus, 0 denotes a possible glitch
