New techniques improving display output and computer system input response are provided.In aspects of the invention, a system assesses whether input gesture(s) occur within an area of an output matrix describing an element, within a time period following a substantial and/or activity-affecting change in that area, and nullifies or alters an affect(s) of the input gesture(s) that would otherwise occur, and may instead or also create the affect that would occur if the output matrix had not experienced the relevant substantial and/or activity-affecting change, and may also reverse, alter, augment or otherwise address the substantial and/or activity-affecting change in that area of the output matrix to enhance the user experience.In other aspects, an object-based projection method increases efficiency and decreases output matrix judder.In additional aspects, a new form of pixel and array, with variably-angled variably-curved pixel subsections, assists in further smoothing edges between objects.
