Abstract: A portable electronic device includes a touch display configured to sense contact with a finger or stylus, a speaker, and a processing system that communicates with the touch display and the speaker. The device is configured to display a symbol using a set of trace indicator line segments comprising a trace direction indicator and a trace termination indicator and to highlight a region of a first of the trace indicator line segments. The device is configured to detect user touch input at multiple locations on the touch display and determine whether the first trace indicator line segment has been traced from the highlighted region to the termination indicator in a direction corresponding to the trace direction indicator, and in response, to draw and maintain a color line corresponding to the detected user touch input at the multiple locations.
