我們以右上圖塊中,右方那個擬節點50來舉例說明,此區域5002中有六個感應器32,六個感應器32的彎折強度分別為 C 1 、 C 2 、 C 3 、 C 4 、 C 5 、 C 6 ,六個感應器32的彎折軸向α分別為α 1 、α 2 、α 3 、α 4 、α 5 、α 6 ,跟擬節點50的距離分別為 d 1 、 d 2 、 d 3 、 d 4 、 d 5 、 d 6 。 We take the example of the quasi-node 50 on the right in the upper right block. There are six inductors 32 in this area 5002. The bending strengths of the six inductors 32 are C 1 , C 2 , C 3 , C 4 , respectively. , C 5 , C 6 , the bending axes α of the six inductors 32 are α 1 , α 2 , α 3 , α 4 , α 5 , α 6 , respectively, and the distances from the analog nodes 50 are d 1 , d , respectively . 2 , d 3 , d 4 , d 5 , d 6 .
彎折資訊統析模組35將擬節點50所在區域涵蓋之每一個感應器32之彎折強度以及彎折軸向以加權平均統合為至少一特徵值,此特徵值包含擬節點彎折量 C m 以及彎折軸向角度α m 。進一步解釋,彎折資訊統析模組35將擬節點50所在區域5002涵蓋之每一個感應器32之彎折強度 C以加權平均統合為擬節點彎折量 C m ,並且彎折資訊統析模組35將擬節點50所在區域5002涵蓋之每一個感應器32之彎折軸向α以加權平均統合為彎折軸向角度α m 。其中所述加權之權值 W係與擬節點50與感應器32之距離 d為正相關,則擬節點彎折量 C m 以及彎折軸向角度α m 係為所述之彎折資訊。 The bending information analysis module 35 integrates the bending strength and the bending axis of each of the inductors 32 covered by the region of the quasi-node 50 into at least one eigenvalue by weighted averaging, and the eigenvalue includes the quasi-node bending amount C. m and the bending axial angle α m . Further, the bending information analysis module 35 integrates the bending strength C of each of the inductors 32 covered by the region 502 of the quasi-node 50 into a quasi-node bending amount C m and bends the information analysis model. Group 35 combines the bending axes a of each of the inductors 32 covered by the region 502 of the pseudonodes 50 into a weighted average angle α m . Wherein the weighted weight W is positively correlated with the distance d between the quasi-node 50 and the inductor 32, and the pseudo-node bending amount C m and the bending axial angle α m are the bending information.
配合圖例說明計算式,六個權值 W n =exp^(d n 2/2),n=1~6。所以,擬節點彎折量 C m= ( W 1C 1+ W 2C 2+ W 3C 3+ W 4C 4+ W 5C 5+ W 6C 6 )/( W 1+ W 2+ W 3+ W 4+ W 5+ W 6 ); 彎折軸向角度α m= ( W 1 α 1 + W 2 α 2 + W 3 α 3 + W 4 α 4 + W 5 α 5 + W 6 α 6 )/( W 1+ W 2+ W 3+ W 4+ W 5+ W 6 )。擬節點彎折量 C m 以及彎折軸向角度α m 就為所述之彎折資訊,後續,手勢對應模組36將擬節點彎折量 C m 以及彎折軸向角度α m 分別比對相對應之閾值,可以得到每一個擬節點50的結果狀態。 The calculation formula is described with the legend, six weights W n =exp^(d n 2 /2), n=1~6. Therefore, the pseudonode bending amount C m = ( W 1 C 1 + W 2 C 2 + W 3 C 3 + W 4 C 4 + W 5 C 5 + W 6 C 6 ) / ( W 1 + W 2 + W 3 + W 4 + W 5 + W 6 ); bending axial angle α m = ( W 1 α 1 + W 2 α 2 + W 3 α 3 + W 4 α 4 + W 5 α 5 + W 6 α 6 ) / ( W 1 + W 2 + W 3 + W 4 + W 5 + W 6 ). The pseudo-node bending amount C m and the bending axial angle α m are the bending information, and subsequently, the gesture corresponding module 36 compares the pseudo-node bending amount C m and the bending axial angle α m respectively. The resulting state of each of the quasi-nodes 50 can be obtained from the corresponding threshold.

In Fig. 6, the pseudo-node bending amount C m of the pseudo-node 1 is 20, and the bending axial angle α m is 30. After comparing the above threshold values, the corresponding result state is also the result state 2. In Fig. 6, the quasi-node bending amount C m of the quasi-node 2 is 4, and the bending axial angle α m is 60. After comparing the above threshold values, the corresponding result state is the result state 1.
