Abstract:
Solutions, systems, and techniques for applying 2-dimensional changes to a shared document are discussed. The document is divided into vertical columns of a particular width, each column represented as a one-dimensional vector that is a sequential list of blocks in that column, each block representing a content item included in the document. Each block has a starting column, a block height, and a block width indicated by how many columns the block occupies. Each block has row indexes that represent a relative position of the block in each column it occupies. A document modification command is represented as transfer functions, each transfer function corresponding to a document column. The transfer functions are applied to the document columns to alter a row index of block(s) in the corresponding column(s), thereby altering the relative position of a block with respect to other blocks in that column.
Abstract:
An example method includes designating a corner region of a display device as active, and outputting, for display at the display device, a user interface including at least one element positioned at a first location substantially diagonally opposite and at a first distance from the active corner region. The method further includes receiving an indication of a gesture interpreted by the computing device as originating within the active corner region and terminating within a center region of the display device, and responsive to receiving the indication of the gesture, outputting, for display at the display device, an updated user interface including the element positioned at a second location a second distance from the active corner region.
