Abstract: A gesture-based construction project collaboration system includes a design information storage for storing a 2D plot or a 3D model of a building; a local information storage for storing local information mapped to location information in the 2D plot or the 3D model; a display for displaying the 2D plot or the 3D model from the design information storage and a desired part of the local information represented by at least one of a touch input and a gesture of a user; a gesture defining section for storing input gestures with respect to types of the local information; and a control section for detecting the location information selected by the user via the touch input on the display, and for controlling the display to display the part of the local information represented by the gesture with respect to the location information.

Abstract: A system for location-based construction project management includes a design information storage section for storing a 2D plot or a 3D model of a building, a work place code storing means, being deployed at each work place of the building, and for storing location information of the work place, a wireless terminal being provided with local information of the work place and location information in addition to the work place code storing means, a work place mapping section for mapping the location information and a locational numeric data of the work place within the 2D plot or the 3D model stored in the design information storage section and a construction information storage section for storing the local information being provided into the wireless terminal, as linked with the locational numeric data mapped by the work place mapping section.

Abstract: A touchpad in which a user input is received includes at least first through third zones, with the first zone and the third zone being non-adjacent. The touchpad further includes at least first and second non-overlapping sensors, with the first sensor disposed in at least a portion of the first and the second zones and configured to transmit a first electrical signal in response to a user input, and the second sensor disposed in at least a portion of the first and the third zones and configured to transmit a second electrical signal in response to a user input. Moreover, the touchpad includes a controller configured to generate first information in response to receiving the first electrical signal but not the second electrical signal, second information in response to receiving both the first electrical signal and the second electrical signal, and third information in response to receiving the second electrical signal but not the first electrical signal.
