Method for hosting mobile access to high-resolution electroencephalography data

A method for hosting mobile access to dense electroencephalography data comprising:

• over a first period of time:
• downloading a first sequence of raw signal points recorded during an EEG test executed on an electroencephalography headset, the first sequence of raw signal points read from a first sense channel in the electroencephalography headset during the first period of time;
• receiving a request to view data from the first sense channel within a viewport rendered on a display of a client computing device, a display resolution of the display, a size of the viewport from the client computing device, and a zoom level within the viewport;
• initializing a first static image;
• calculating a first quantity of raw signal points per pixel column of the first static image based on the display resolution, the size of the viewport, and the zoom level;
• for each discrete contiguous sequence of the first quantity of raw signal points in the first sequence of raw signal points:
• extracting a minimum value from the discrete contiguous sequence of raw signal points;
• extracting a maximum value from the discrete contiguous sequence of raw signal points;
• calculating an average of the discrete contiguous sequence of raw signal points;
• and
• calculating a standard deviation of the discrete contiguous sequence of raw signal points;
• representing the minimum value, the maximum value, the average, and the standard deviation in a set of color values in pixels in a pixel column of the first static image, the pixel column corresponding to a time window spanned by the discrete contiguous sequence of the first quantity of raw signal points in the first sequence of raw signal points;
• transmitting the first static image to the client computing device, via a computer network, for rendering within the viewport;
• and
• over a second period of time immediately succeeding the first period of time:
• downloading a second sequence of raw signal points from the electroencephalography headset, the second sequence of raw signal points read from the first sense channel during the second period of time;
• for each discrete contiguous sequence of the first quantity of raw signal points in the second sequence of raw signal points, compressing the discrete contiguous sequence of the second quantity of raw signal points into a value set;
• generating a second static image representing value sets of discrete contiguous sequences of the second quantity of raw signal points along the second sequence of raw signal points;
• and
• transmitting the second static image to the client computing device for rendering within the viewport adjacent and succeeding the first static image.

A method for hosting mobile access to dense electroencephalography data comprising:

• receiving a set of signals, in a raw resolution, recorded by a set of channels in an electroencephalography headset during an electroencephalography test executed on the electroencephalography headset;
• receiving, from a client computing device, a size of a viewport rendered on a display of the client computing device and a display resolution of the display;
• calculating a first quantity of raw signal points per pixel column of the display based on the display resolution, the size of the viewport, and a length of a first segment of the electroencephalography test;
• for each signal in the set of signals:
• for each discrete contiguous sequence of the first quantity of raw signal points within the first segment of the signal:
• extracting a minimum value from the discrete contiguous sequence of raw signal points;
• extracting a maximum value from the discrete contiguous sequence of raw signal points;
• calculating an average of the discrete contiguous sequence of raw signal points;
• and
• calculating a standard deviation of the discrete contiguous sequence of raw signal points;
• representing the minimum value, the maximum value, the average, and the standard deviation in a set of color values in pixels in a pixel column of the first static image, the pixel column corresponding to a time window spanned by the discrete contiguous sequence of the first quantity of raw signal points within the first segment of the signal;
• transmitting the first static image to the client computing device, via a computer network, for rendering.
