Techniques for adjusting a drying time of digital ink
View Patent ↗A technique that facilitates modifying (e.g., erasing or smudging) digital ink includes selecting a digital ink drying time based on a selected digital ink type. An ink stroke associated with the selected digital ink type is then tracked. The ink stroke may then be modified, prior to an end of the digital ink drying time, without using a dedicated tool.
1. An apparatus, comprising:
a stylus;
a touchscreen display capable of receiving a first input from a user via said stylus, and in turn displaying said first input, wherein said touchscreen display is also capable of receiving a second input from said user for modifying said first input via a non-electrical tool, and in turn displaying a result of said modification;
a memory for storing a plurality of digital ink types, each of said digital ink types is associated with a specific drying time; and
a processor coupled to said memory and said touchscreen display, wherein said processor is configured to:
track strokes of said first input using one of said digital ink types selected by said user; and
modify said strokes of said first input according to said second input from said user if and when said second input is received before a drying time of said selected digital ink type has been reached.
2. The apparatus of claim 1 , wherein said non-electrical tool is a finger of said user.
3. The apparatus of claim 1 , wherein said apparatus is a tablet computer.
4. The apparatus of claim 1 , wherein said apparatus is a personal digital assistant.
5. The apparatus of claim 1 , wherein said apparatus is a mobile phone.
6. A method, comprising:
providing a touchscreen for receiving a first input from a user via a stylus;
tracking strokes of said first input using one of a plurality of digital ink types selected by said user, wherein said plurality of digital ink types are stored in a memory coupled to said touchscreen, each of said digital ink types is associated with a specific drying time;
displaying said strokes of said first input;
in response to a receipt of a second input from said user for modifying said first input via a finger of said user, modifying said strokes of said first input according to said second input from said user if and when said second input is received before a drying time of said selected digital ink type has been reached; and
displaying a result of said modification on said touchscreen.
