TOUCH SCREEN FINGER TRACING DEVICE

摘要

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.

主权项

1. A portable electronic device having a touch user interface, the portable electronic device comprising:
a touch display configured to sense contact with a finger or stylus and to display visual content; a speaker; a processing system comprising at least one computing device, the processing system configured to communicate with the touch display and the speaker; and non-transitory memory that stores instructions that when executed by the processing system cause the portable electronic device to perform operations comprising:
display a first iteration of a first symbol, wherein the first iteration of the first symbol is displayed without trace indicator line segments;generate a sound corresponding to the first symbol using the speaker;display a second iteration of the first symbol using a set of trace indicator line segments comprising a trace direction indicator and a trace termination indicator;highlight an end region of a first of the trace indicator line segments;detect user touch input at a plurality of locations on the touch display;based at least in part on the detected user touch input at the plurality of locations, determine whether the user has traced the first trace indicator line segment from the highlighted end region to the termination indicator in a direction corresponding to the trace direction indicator;draw and maintain a color line corresponding to the detected user touch input at the plurality of locations at least partly in response to a determination that the user has traced the first trace indicator line segment from the highlighted end region to the termination indicator in a direction corresponding to the trace direction indicator.
