  "abstract": "<p>This dataset contains data for hand gesture recognition recorded with 3 different sensors.&nbsp;</p>\n\n<p>sEMG: recorded via the Myo armband that is composed of 8 equally spaced non-invasive sEMG sensors that can be placed approximately around the middle of the forearm. The sampling frequency of Myo is 200 Hz. The output of the Myo is a.u&nbsp;</p>\n\n<p>DVS: Dynamic Video Sensor which is a very low power event-based camera with 128x128 resolution</p>\n\n<p>DAVIS: Dynamic Video Sensor which is a very low power event-based camera with 240x180 resolution that also acquires APS frames.</p>\n\n<p>The dataset contains recordings of 21 subjects. Each subject performed 3 sessions, where each of the 5 hand gesture was recorded 5 times, each lasting for 2s. Between the gestures a relaxing phase of 1s is present where the muscles could go to the rest position, removing any residual muscular activation.</p>\n\n<p>&nbsp;</p>\n\n<p>Note: All the information for the DVS sensor has been extracted and can be found in the *.npy files.

The timestamps are in seconds and synchronized with the Myo. Each file is in the format `subjectXX_sessionYY_dvs` with `XX` subject ID (01 to 21), `YY` session ID (01-03).</p>\n\n<p>&nbsp;</p>\n\n<p>- relax21_cropped_aps.zip: contains the 40x40 pixel aps frames for all subjects and trials in the format `subjectXX_sessionYY_Z_W_K` with `XX` subject ID (01 to 21), `YY` session ID (01-03), Z gesture (&#39;pinky&#39;, &#39;elle&#39;, &#39;yo&#39;, &#39;index&#39;, &#39;thumb&rsquo;), W trial ID (1-5), `K` frame index.</p>\n\n<p>&nbsp;</p>\n\n<p>- relax21_cropped_dvs_emg_spikes.pkl: spiking dataset that can be used to reproduce the results in the paper. The dataset is a dictionary with the following keys:</p>\n\n<ul>\n\t<li><strong>- </strong><strong>y</strong>: array of size 1xN with the class (0-&gt;4).</li>\n\t<li><strong>- </strong><strong>sub</strong>: array of size 1xN with the subject id (1-&gt;10).</li>\n\t<li><strong>- </strong><strong>sess</strong>: array of size 1xN with the session id (1-&gt;3).</li>\n\t<li><strong>- </strong><strong>dvs</strong>: list of length N, each object in the list is a 2d array of size 4xT_n where T_n is the number of events in the trial and the 4 dimensions rappresent: 0 -&gt; addr_x, 1 -&gt; addr_y, 2 -&gt; timestamp, 3 -&gt; polarity .</li>\n\t<li><strong>- </strong><strong>emg</strong>: list of length N, each object in the list is a 2d array of size 3xT_n where T_n is the number of events in the trial and the 3 dimensions rappresent: 0 -&gt; addr, 1 -&gt; timestamp, 3 -&gt; polarity.</li>\n</ul>\n\n<p>&nbsp;</p>\n\n<p>&nbsp;</p>",
