MeganePro dataset 4 (MDS4)

<h1> General Information </h1> The dataset contains the data of hand and phantom limb repositioning in the presence of hindering physical matter (Exercises 4-5) acquired during the <a href='http://ninaweb.hevs.ch/MeganePro'>Myo-Electricity, Gaze And Artificial-intelligence for Neurocognitive Examination & Prosthetics (MeganePro) project</a>. The data were collected to examine the changes in phantom limb sensations and eye movement patterns in reaction to a physical object invading the phenomenal space of a phantom limb. Motor imagery and motor execution were both considered. These data are relevant to the way the phantom interacts with a prosthesis, and might provide useful insights into the mechanism underlying the embodiment of an artificial limb. The data represents the first-ever attempt to characterise quantitatively phantom limb phenomena hitherto only described in self reports. The dataset includes surface electromyography (sEMG), accelerometry, gaze, and video of scene in first-person perspective. <h1> Acquisition Protocol </h1> Task 2 (indicated as exercise n.4).
