Touch display device with tactile feedback

An apparatus comprising at least one processor and at least one non-transitory memory including computer program code for one or more programs, the at least one non-transitory memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:

• determine at least one image parameter with respect to at least one image displayed on at least one display;
• determine at least one image edge based on the at least one image parameter based, at least partially, on determining at least one discontinuity in the at least one image;
• determine:
• at least one plane within the at least one image edge, and
• at least one polygon within the at least one image edge
• based, at least partially, on the at least one image edge comprising at least one of:
• a plurality of contiguous or partially contiguous edges, or
• a continuous or partially continuous edge;
• generate at least one edge parameter value associated with the at least one image edge, wherein a tactile effect is associated with the at least one edge parameter value;
• generate at least one plane parameter value associated with the at least one plane;
• generate at least one polygon parameter value associated with the at least one polygon;
• determine at least one touch parameter when at least one touch input is detected with respect to the at least one display configured to display the at least one image;
• and
• generate at least one tactile signal at a location of the at least one detected touch input, when the at least one detected touch input at least partially interferes with the at least one image, wherein the at least one tactile signal comprises a predetermined signal selected based on:
• the location of the at least one detected touch input, and
• the at least one determined polygon,
• wherein the selected predetermined signal is modified for generation at the location based on the at least one touch parameter and at least one of:
• the at least one edge parameter value,
• the at least one plane parameter value, or
• the at least one polygon parameter value, and
• where the at least one tactile signal is configured to generate the tactile effect, comprising both haptic feedback from the at least one display and audio from the at least one display, wherein the at least one display comprises a tactile audio display component actuated with at least one actuator, wherein the tactile effect is localized at a sub-region of the at least one display proximate the location where the at least one detected touch input at least partially interferes with the at least one image.
