Abstract: Various embodiments herein provide for a method of receiving user input on a touch screen. A hover gesture can be detected and an action performed in response to the detection. The hover gesture can occur without a user physically touching a touch screen. Instead, the user's finger or fingers can be positioned at a spaced distance above the touch screen. The touch screen can detect that the user's fingers are proximate to the touch screen, such as through capacitive sensing. Additionally, finger movement can be detected while the fingers are hovering.

Abstract: Techniques are described herein that are capable of performing an action on a touch-enabled device based on a gesture. A gesture (e.g., a hover gesture, a gaze gesture, a look-and-blink gesture, a voice gesture, a touch gesture, etc.) can be detected and an action performed in response to the detection. A hover gesture can occur without a user physically touching a touch screen of a touch-enabled device. Instead, the user's finger or fingers can be positioned at a spaced distance above the touch screen. The touch screen can detect that the user's fingers, palm, etc. are proximate to the touch screen, such as through capacitive sensing. Additionally, finger movement can be detected while the fingers are hovering to expand the existing options for gesture input.

Abstract: Disclosed herein are representative embodiments of tools and techniques for performing contextual searches using text determined based on digital-ink data. According to one exemplary technique, digital-ink data is received at a computing device and text is determined based on the digital-ink data. Additionally, by an application of the computing device, a contextual search is performed using the text.
