At this time, the gravity of _g is measured on the z-axis (due to the z-axis: reverse) Negative value), that is, the state shown in Figure 38. On the contrary, if the casing (1) is horizontally turned 18 〇 & so that the second panel (10) faces upward and the panel (8) faces downward, the z-axis turns downward, and the gravity still completes, due to the gravity direction and the z-axis. The same, so the Z axis is measured, two: =: (3) that is to use the principle to determine the first panel (1) or the first: and then control the relay (4) to make the upward-side key 彳 energy state, the other side is Inverted disability state. ^图图图和五图, the material of the present invention (4) force sensor (2) obtains the three-dimensional right angle coordinate of the force knife value (10), that is, the X-axis component gx, the y-axis component s 1338137 The first-stage discrimination result (S2) is generated by the magnitude of the Z-axis component. When the Z-axis component is greater than lg or less than _lg (S2a, S2e), that is, the z-axis component = the pair value, the judgment is ignored (d0n, t care) (s4c), that is, to maintain the original state, without change, the 1 § is a first critical value, because in the static state, the gravity component of any one axis is not greater than lg or less than _lg, greater than [or less than -lg means that the handheld device is in motion. At this time, the user should not be operating the handheld device, so no switching action is generated. However, lg is only the first critical value and a theoretical value, and is not static. It can be selected as a critical value in the range of 1.2 § to 2 §, and sputum is particularly preferred. When the z-axis component is less than _〇.5g and greater than or equal to the negative value of the first critical value (3)b), the first orientation (four) is formed (_) that is, one of the first panel (8) or the second panel (12) is upward. If it is separated as shown in the third figure, that is, the first panel (9) is upward; when the 2-axis component is less than or equal to the positive value of the first threshold and greater than 〇. 5g (S2d), it is determined as the second orientation state (S4b) ''is opposite to the aforementioned first orientation state, the other side: up, right to the state shown in the third figure, ie the second panel ((2) the upward component is less than or equal to o.5g and greater than or equal to _G.5g* (S2c ), that is, by "quantity = negative (S3) and y-axis component size (10), Qing as the second phase of the miscellaneous two, when the 2-axis component is negative (10)), and the second critical value is greater than 0 陶陶, discriminant state (S4a) 'is the same as the aforementioned -th limit value, the second best ^ i is equal to or equal to 1g, or (4) can be selected, from 1.3⁄4 as a component is negative (10))...the axial component is smaller than ... when the negative value of the threshold is (10)b) 'determined as the second orientation 9 1338137 state (S4b). And when the z-sleeve component is positive (S3Y), and the 乂-axis component is less than · equal to the second When the positive value of the boundary value is greater than ❿(3)(6), the azimuth state (S4b) is positive (S3Y), and the iy axis component is 0'5g and is greater than or equal to the negative value of the second threshold (8). Sorry (S4a). If the y-axis component is not within the above range (S31a ' S32a), including the z-axis stalk ndt ignores (S4c). The Z-axis knife is dedicated to 0 when 'the law is discriminant In order to achieve the above-mentioned discriminating method of the invention, the size of the three-axis component of gravity can be determined by the size of the three-axis component of the gravity, and it is extremely simple, and the calculation is simple, and the ugly time can be reduced. The need for the performance of the microprocessor is only the equivalent of the specific embodiment of the preferred embodiment of the present invention. The equivalent of the invention is the patent scope of the present invention.
