发明实施例
本发明的实施方式
[0044] 为了对本发明的技术特征、 目的和效果有更加清楚的理解, 现对照附图详细说 明本发明的具体实施方式。
[0045] 图 1示出了本发明一些实施例中的圆柱形触控装置, 用于在圆柱形装置上实现 触控功能。 结合图 1和图 2所示, 本发明一些实施例中的圆柱形触控装置包括圆 柱形本体 10、 触控屏 20和控制器 30, 其中, 触控屏 20设置在圆柱形本体 10侧表 面, 触控屏 20上的柔性感应电极 25用于接收外部触控动作; 控制器 30与柔性感 应电极 25相连接, 根据触控动作判断是否跨越边界并输出数据结果, 从而供后 续数据处理使用。
[0046] 其中, 触控屏 20为柔性触控屏 20, 其倾斜缠绕并包覆于圆柱形本体 10侧表面, 触控屏 20上设置有“西洋双陆棋”式的柔性感应电极 25结构, 从而供使用者在圆柱 形本体 10侧表面进行触控操作。 本实施例中, 结合图 3&-3〇所示, 如图 中为柔 性感应电极 25的常见排布方式, 每个柔性感应电极 25呈直角三角形, 构成触控 屏 20为矩形; 将图 3&的触控屏 20倾斜一定角度成为图 315; 之后再将图 31?的顶部和 底部切平以便于安装, 从而得到本实施例中的平行四边形触控屏 20, 以及细长 三角形柔性感应电极 25。 可以理解地, 触控屏 20在圆柱形本体 10侧表面上非重 叠设置。 优选地, 触控屏 20的边界之间相距均在 0.3111111以内, 这样的好处是, 即 降低了工艺难度, 又不影响触控屏 20的正常使用。 此外, 整个
选择了四个 通道 (两组对插三角形) 来设计, 而不是用两个通道, 因为如果只用两个通道

[0057] 本发明一些实施例中还提供触控屏 20, 该触控屏 20与上述实施例圆柱形触控装 置中的触控屏 20相当, 此处不再赘述。
[0058] 以下结合图 1-8和本发明一些实施例中的触控方法对本发明一些实施例中圆柱 形触控装置的工作原理进行说明。 本发明一些实施例中的触控方法用于控制上 述实施例的圆柱形触控装置执行如下步骤 3144。

[0061] 在步骤 33中, 根据起始坐标数据和终点坐标数据判断触控动作是否跨越边界, 若是, 则执行步骤 34; 若否, 则输出直接数据结果。 具体地, 结合图 6、 7&-7(1所 示, 对触摸位置识别原理进行说明。 按照图 6中箭头所指方向, 依次以 、 :8、 0 和0四个触摸点为例说明。 如图 7&的八到:8过程中, 所经过的柔性感应电极按照 图中图案分别为: 空白-网格-空白-线条; 类似于普通的横三角触摸屏上斜着画 了条斜线, 触控动作未跨越边界, 输出直接数据结果, 按照常规的坐标计算方 法很容易就能识别。 如图 7(1的(:到0过程与八到:8过程同理, 所经过的柔性感应电 极按照图中图案分别为: 空白-网格-空白-线条; 触控动作未跨越边界, 输出直 接数据结果, 按照常规的坐标计算方法很容易就能识别。 如图 7〇的:8到(:过程中 , 所经过的柔性感应电极按照图中图案分别为: 空白-线条-空白-网格, 跨越了 线条-空白的边界处, 因此该触控动作跨越边界, 因而无法通过常规的坐标计算 方法识别。 此时, 为了方便演示从:8到(:的过程, 所以把通道调了一下, 成为图 7 〇所示的实际效果。 需要说明的是, 本步骤中, 设置一横向边界定值 111、 一纵向 边界定值!1, 判断是否起始坐标数据和终点坐标数据之间的横坐标差与横向边界 定值111的差值在一定范围内、 且纵坐标差与纵向边界定值 的差值在一定范围内

, 若是, 则判断触控动作跨越边界; 若否, 则触控动作未跨越边界。 需要说明 的是, 此处的横向边界定值 111、 纵向边界定值 !1均为根据圆柱形直径、 触控屏 20 倾斜缠绕角度等数据计算而得出的定值。 具体地, 前述起始坐标数据和终点坐 标数据之间的横坐标差与横向边界定值 111的差值范围在 5%以内, 优选地, 该差 值范围在 3%以内; 前述纵坐标差与纵向边界定值!1与纵向边界定值!1的差值范围 在 5%以内, 优选地, 该差值范围在为 3%以内。
[0062] 在步骤 34中, 进行数据计算, 并输出间接数据结果。
[0063] 可以理解地, 后续数据处理过程中, 若接收到控制器 30输出的直接数据结果, 可直接通过常规的坐标计算方法识别当前触控动作; 若接收到控制器 30输出的 间接数据结果, 则需要将起始坐标数据和终点坐标数据的横坐标和纵坐标进行 换算, 使得两点通过坐标转换连成线, 再通过常规的坐标计算方法识别当前触 控动作。 从而, 完成对在圆柱形触控装置上触控动作的识别。
