Abstract

PURPOSE:To decrease the size of a sense panel surface by attaching a sensor to a penholder to sense the force applied to the pen point or the vector of displacement, and indicating the input of characters to a computer, etc. according to the vector change in terms of time. CONSTITUTION:Two pairs of X and Y direction sensors containing piezoelectric elements are attached to the pen point of a pen type data input device to sense the force applied to the pen point or the vector of displacement. Then the conduction rubber is set between the core of the pen and a case serving as the pen holder. Thus the force or displacement detected by the sensors is extracted according to the change of the resistance value of said conduction rubber. In another example, a permanent magnet is attached to the pen core and the movement of the pen is detected by a coil attached to the main body of the pen. The characters are supplied to a computer 3 via a vector pattern analyzer 2 based on the change of vector in terms of time.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a data input instrument having a sensor that senses the entire vector of force or displacement applied to the pen tip on the shaft of the pen.

Generally, humans are accustomed to writing detailed characters using a pen or pencil, and the pen-type input method is considered one of the most suitable methods.

Conventionally, pen-type digitizers have been used for this purpose, but they have the drawback of requiring the entire surface of a large sense plate.

The present invention does not depend on the position of the pen or the amount of movement of the mouse, etc.
It is a device that allows us to know all the human intentions by fully sensing the force applied to the pen itself.The feature is that the pen can be used in a natural writing state, so it does not take up much space and does not require a specific place. It is possible to enter data and issue commands to a computer in the same natural way as filling out a document, without having to do so.

An example of this proposal is shown below.

(a) Force applied to the pen tip by two pairs of piezoelectric elements? , sense.

(b) A method in which a conductive rubber whose resistance value changes with pressure is placed between the pen core and the case of the shaft, and the sound of this change in resistance is captured.

(C) A method to detect all pen movements by attaching a permanent magnet to the pen core and a coil to the pen body.

In either embodiment, of the three components of the force or displacement vector applied to the pen, only two components perpendicular to the axis are sufficient in practice.

Also, to make it easier to understand the direction of the pen, the cross section of the pen is shown below.
It was shaped like an inverted triangle.
