A system, method and non-transitory, computer-readable storage medium are disclosed for implementing dynamic layout rules for attributed text strings having different type styles. In some implementations, developers can use an Application Programming Interface (API) or a design tool to specify dynamic text layout rules for rendering attributed text strings in a user interface (UI). Various text attributes associated with the different type styles (e.g., font metrics) are dynamically adjusted based on the dynamic text layout rules to improve the readability of the text when, for example, font sizes are adjusted. In some implementations, one or more parameters of a text container, text container region, line-fragment or display object are dynamically adjusted based on the dynamic text layout rules to improve the readability of the text.

Methods, apparatus, systems are disclosed for altering displayed content on a display device responsive to a user's proximity. In accord with an example, a computing system includes a display, a sensor to output a signal, machine readable instructions, and programmable circuitry to be programmed in accordance with the instructions to intermittingly determine a distance between the compute system and a person based on the signal, and cause a size of at least one object to be presented on the display to be adjusted based on the distance.

A device for improving readability of content displayed to a viewer is provided. The device has a screen for displaying the content, a motion sensor for measuring a displacement, and an eye tracker for measuring a change in gaze of the viewer when gazing at the screen. The device is operative to adjust the displayed content so as to improve its readability in response to determining that the change in gaze and the displacement of the device are out-of-sync. The out-of-sync condition may be determined by deriving a phase difference between the measured change in gaze and the measure displacement of the device, and comparing the derived phase difference to a threshold value. The displayed content is adjusted by at least one of increasing a font size of displayed text, enlarging one or more displayed graphical objects, and increasing a zoom level of the displayed content.

A system may render glyphs based on stored textures without loss of quality at subpixel scales. The system may determine a content of a pixel of a display corresponds to a glyph, determine a subpixel alignment offset of a specified screen coordinates for the glyph with respect to the pixels of the display, based on the subpixel alignment offset, select one or more versions of the glyph from a plurality of versions of the glyph, a first version of the glyph of the plurality of versions of the glyph having a corresponding first subpixel alignment offset and a second version of the glyph of the plurality of versions of the glyph having a corresponding second subpixel alignment offset, and generate a display version of the pixel based on the selected one or more versions of the glyph and the subpixel alignment offset of the specified screen coordinates.

A character adjustment method is used for adjusting the character so as to output the character to a second pixel matrix of an output device. The character is designed in a first pixel matrix. The method includes determining a constant, an upper density limit and a lower density limit according to at least one feature value of the output device; performing an interpolation calculation for obtaining a variation parameter according to a density of the character in the first pixel matrix, the constant, the upper density limit and the lower density limit; adjusting the character according to the variation parameter; and outputting the adjusted character to the second pixel matrix by the output device.

An information processing device sets a second scaling factor used to display a character image extracted from an image. The second scaling factor is different from a first scaling factor used to display a background image extracted from the image. The information processing device adjusts at least either the character image changed in display size with the second scaling factor or the background image changed in display size with the first scaling factor, based on the relationship between the display state of the character image changed in display size and the display state of the surrounding area of the character image that has been changed in display size and is overlaid on the background image changed in display size.

A system for scaling visualizations may include a human machine interface (HMI) configured to display a visualization on a screen, a secondary display device configured to display a scaled visualization such that the scaled visualization is determined based at least in part on the visualization, and a controller. The controller may be configured to receive an indication that the secondary display device has been coupled to the HMI, present two or more scaling mode options on the screen or the secondary display device, receive an input that corresponds to one of the scaling modes, generate the scaled visualization by applying a scaling factor to the visualization, wherein the scaling factor is based at least in part on the input, and facilitate sending the scaled visualization to the secondary display device.
