Provided is a mobile terminal characterized by comprising: a display unit which outputs visual information; a depth camera which captures a subject and acquires a depth image; a memory which stores a vein pattern of a user's hand; and a control unit connected to the display unit, the depth camera, and the memory. The control unit identifies the shape of the user's hand from the depth image, authenticates the user using a pre-stored user vein pattern, and when the user is authenticated, executes a specific application in response to a three-dimensional gesture of the user's hand, and omits an authentication procedure required by the specific application.

Systems and methods for optically measuring a position of a measurement surface relative to a reference position. The system is a wireless network comprising a centrally located data acquisition computer and a multiplicity of remotely located sensor modules mounted at different locations within wireless communication range of a central receiver. Each sensor module is mounted to a clamp that is made specific to a control surface location and embedded with an RFID tag to denote clamp location. The optical components of the sensor modules are selected to enable indication of the linear position of a measurement surface relative to a reference position and then broadcast the measurement results. The broadcast results are received by the central receiver and processed by the data acquisition computer, which hosts human interface software that displays measurement data.
