The smart finger, a concept designed by Jung Ji-hye, Choi Hyong-Suk and Yoo-Jin Park, is the extension of weak human hands which facilitates the distance measurement easily and rapidly.
Smart Fingers
This functions by transmitting a signal between the thumb sensor and the fingertip sensor, by calculating the time taken required for the signal to arrive at the receiving sensor, with high precision.
Upon measurement of the distance, it is projected on an in-built LCD. The units can even be programmed for additional calculations such as the area, the volume of the calculated area, etc.
For measuring a larger object, the Smart Finger systems can be put on each hand’s index finger if the objects to be measured are as large as the supported armspan. The designers are not sure about the total distance that can be measured by this design.
The design supports different measurement units and the Smart Fingers will convert the units automatically upon pressing the button. The measurement data is stored in the internal memory of the device, and a docking unit enables the charging of batteries during the transfer of recorded calculations to an application PC.
The neat and smooth design of the Smart Fingers allows the clipping of both the units in a single object for retention. The sensors are integrated in a smooth inner silicone surface for firm and gentle attachment to the fingertip.
