Abstract: Systems and techniques are described for automated zoom and selection of content on a touch screen device. A described technique includes receiving a first touch input contacting a touch screen display of a user device at a first position in a user interface presented at a first magnification, while continuing to receive the first touch input determining that a duration of the first touch input has exceeded a predetermined threshold duration, and increasing, based on determining that the duration of the first touch input has exceeded than the predetermined threshold duration, the magnification of the user interface to a second magnification, and performing an action based on the first touch input.

Abstract: A method is provided for a presenter device to screen share a remote desktop on a remote server with participant devices in a wireless network including the presenter device and the participant devices. The presenter device connects to the remote desktop through the wireless network. The presenter device receives screen data of the remote desktop and multicasts the screen data to a multicast group through the wireless network. The presenter device transmits a multicast address to the participant devices through the wireless network. The participant devices use the multicast address to receive the screen data through the wireless network.

Abstract: Left- and right-click buttons of a virtual touchpad each have two modes, a “click” mode and an “on/off” mode. In “click” mode, touching a finger to the left- or right-click button triggers a mouse button down event while releasing a finger from the button triggers a mouse button up event. In “on/off” mode, the left- and right-click buttons each have two states, “on” and “off.” If the current state of the left- or right-click button is “off,” then touching the button triggers the mouse button down event, while releasing the button changes the state of the button to “on” but does not trigger any mouse events. Conversely, if the current state of the left- or right-click button is “on,” then touching the button does not trigger any mouse events, but releasing the button thereafter changes the state of the button to “off” and triggers the mouse button up event.
