为使本领域技术人员更好地理解本发明的技术方案， 下面结 合附图和具体实施方式对本发明的穿戴式触控装置和穿戴式触控 方法作进一步详细描述。
一种穿戴式触控装置， 其特征在于， 包括载体、 投影单元、 监测单元和处理单元， 其中： 所述载体能穿戴； 所述投影单元向 触控端能触摸到的触控面进行投影； 所述监测单元用于监测所述 触控端与所述触控面之间的接触信息， 并将所述接触信息发送至 所述处理单元； 所述处理单元用于对所述接触信息进行处理， 以 判断所述触控端是否与所述触控面有效接触。
一种穿戴式触控方法， 其特征在于， 包括： 向触控端能触摸 到的触控面进行投影； 监测所述触控端与所述触控面之间的接触 信息； 对所述接触信息进行处理， 以判断所述触控端是否与所述 触控面有效接触。
该穿戴式触控装置及相应的穿戴式触控方法保证了触控的有 效性。 实施例 1 :
本实施例提供一种穿戴式触控装置和相应的穿戴式触控方 法。
如图 1 所示， 本实施例中的穿戴式触控装置包括载体 1、 投 影单元 （图 1中未示出） 、 监测单元 2和处理单元 3。
载体 1 能穿戴， 例如能穿戴于人体手指上， 从而包含载体 1 的穿戴式触控装置通过载体 1穿戴于人体（例如人体手指） 上。
所述投影单元向触控端 4能触摸到的触控面 5 (参见图 2 )进 行投影。
监测单元 2用于监测所述触控端与所述触控面之间的接触信 息， 并将所述接触信息发送至处理单元 3。
处理单元 3用于对所述接触信息进行处理， 以判断所述触控 端是否与所述触控面有效接触。
如图 2所示， 所述触控端 4 可以为人体手指， 所述触控端 4 能触摸到的触控面可以为人体手指所能触摸到的人体自身的其他 区域（例如手掌） ， 即所述触控面 5 可以形成于例如手掌上。 该 情况下， 当所述触控端 4与所述触控面 5接触时， 会形成人体闭 合电流（电压） ， 所述触控端的电阻会发生变化（例如， 减小） 。 但是， 当其他物体 （非导电物体， 具体地， 非人体手指）接触到 所述触控面时， 不会产生人体闭合电流。 由此， 可以监测所述触 控端与所述触控面之间是否形成人体闭合电流 （例如， 通过监测 所述触控端的电阻是否减小一定程度） 来判断所述触控端是否与 所述触控面有效接触， 从而避免了非有效接触引起的误触控。 在 本实施例中， 所述触控面可以形成于所述触控端能直接接触到的 人体自身的其他区域 （除作为所述触控端的人体手指之外） 的任 何曲面或平面。
例如， 当作为所述触控端的人体手指触摸到作为所述触控面 的人体自身的其他区域时， 引起人体手指与人体自身的其他区域 之间的等效电阻发生变化， 从而在人体手指与人体自身的其他区 域之间形成闭合电流。 如图 2 所示， 例如， 当人体的右手手指作 为所述触控端而触摸作为所述触控面的人体自身的左手手掌时， 引起右手手指与左手手掌之间的等效电阻发生变化， 从而在右手 手指与左手手掌之间形成闭合电流。 因此， 可以通过判断右手手 指与左手手掌之间是否形成闭合电流来识别右手手指是否与左手 手掌有效接触， 如果右手手指与左手手掌之间没有形成闭合电流， 则表明右手手指没有与左手手掌有效接触， 即， 没有产生有效触 控。
从可测量的角度考虑， 形成闭合电流最直观的体现是人体的 电阻的变化 （即， 减小） 。 因此， 本实施例中， 所述接触信息可 以包括电阻信息， 所述监测单元 2 可以包括电阻信息釆集单元， 所述电阻信息釆集单元可以是电阻传感器， 所述电阻传感器用于 釆集所述触控端 4 的当前电阻信息， 并将所述当前电阻信息发送 至所述处理单元 3。 当然， 可以理解的是， 所述电阻信息釆集单元 可以是能够测得人体电阻的任何仪器。 通常情况下， 人体电阻受 皮肤状态、 接触面积、 接触压力等多种因素的影响， 可能在很大 的范围内变化。 在本实施例中， 作为所述触控端的人体手指的初 始电阻可按 1000Ω至 2000Ω考虑， 例如， 人体手指的初始电阻可 以为 2000Ω， 当人体右手手指与作为所述触控面的人体左手手掌 有效接触时， 人体右手手指与左手手掌之间会形成非零的闭合电 流 （即， 人体手指的当前电阻相对于初始电阻会减小， 例如减小 量超过 5% ) ， 而当没有形成闭合电流（即， 闭合电流为零） 时， 人体手指没有与人体手掌有效接触。
处理单元 3可以包括对比模块和判断模块（图 1中未示出）， 处理单元 3 内预存有初始电阻信息， 其中， 对比模块用于对比所 述当前电阻信息与所述初始电阻信息， 并将对比结果发送至所述 判断模块， 所述判断模块用于根据所述对比结果来判断所述触控 端与所述触控面之间是否形成人体闭合电流。 优选的是， 处理单 元 3可以釆用微型处理器 （例如单片机） 实现。
在本实施例中， 通过监测所述触控端 （例如人体手指） 的电 阻变化来判断所述触控端是否与所述触控面有效触控。 在通常情 况下， 所述触控端与所述触控面之间所形成的人体闭合电流越大， 所述触控端的电阻变化也就越明显， 从而， 通过监测所述触控端 的电阻变化可实现触控有效' I"生的判断。
优选的是， 载体 1釆用 PVC材料形成， 例如， 可以形成为环 状， 该材料绝缘， 且其形成的结构结实， 因此， 釆用该材料形成 载体 1可使得设置于载体 1 内的各单元的结构和位置稳定， 从而 能保证包含载体 1 的穿戴式触控装置的有效工作， 还能保证穿戴 该穿戴式触控装置的人体的安全。 进一步优选的是， 载体 1 穿戴 于作为所述触控端的人体手指上， 监测单元 2 (例如， 包括电阻传 感器） 和处理单元 3均设置于载体 1 中， 所述电阻传感器设置于 载体 1的内表层， 以便能更好地感测所述触控端的当前电阻信息。
当然， 本实施例中的穿戴式触控装置还可以包括执行单元， 其可以在确定了所述触控端与所述触控面有效接触后， 确定所述 触控端对所述虚拟触控面的具体触控位置， 并获得与该触控位置 相对应的触控命令， 从而 4艮据该触控命令执行相应的触控响应， 在确定了所述触控端没有与所述触控面有效接触后， 可以执行返 回命令以继续监测所述触控端与所述触控面之间的接触信息， 这 里不再详述。
相应地， 本实施例提供一种穿戴式触控方法， 包括以下步骤 S 1至 S 3。
S 1 : 向触控端能触摸到的触控面进行投影。
S2 : 监测所述触控端与所述触控面之间的接触信息。
例如， 所述触控端为人体手指， 所述触控端能触摸到的触控 面为人体手指所能触摸到的人体自身的其他区域（例如， 手掌） ， 所述接触信息包括电阻信息。 监 'J所述触控端与所述触控面之间 的接触信息的步骤可以包括： 釆集所述触控端的当前电阻信息。
S 3： 对所述接触信息进行处理， 以判断所述触控端是否与所 述触控面有效接触。
例如， 对所述接触信息进行处理的步骤包括： 对比所述当前 电阻信息和预存的初始电阻信息； 以及根据对比结果来判断所述 触控端与所述触控面之间是否形成人体闭合电流。 优选的是， 当 所述对比结果显示所述当前电阻信息相对于所述初始电阻信息的 减小量超过 5%时， 判断结果为所述触控端与所述触控面之间形成 人体闭合电流。 当然， 当确定所述触控端与所述触控面有效接触后， 可以进 一步确定所述触控端对所述触控面的具体触控位置， 并获得与该 触控位置相对应的触控命令， 从而根据该触控命令执行相应的触 控响应， 当确定了所述触控端没有与所述触控面有效接触后， 可 以执行返回命令（例如返回至步骤 S2 ) 以继续监测所述触控端与 所述触控面之间的接触信息， 这里不再详述。
图 3所示为本实施例中的穿戴式触控方法的触控流程图。 该穿戴式触控方法中， 所述触控端为人体手指， 所述触控端 能触摸到的触控面为人体手指所能触摸到的人体自身的其他区域 (例如， 手掌） ， 即， 所述触控面形成于例如手掌上。
首先， 进行初始化， 例如预存所述触控端的初始电阻信息。 然后， 监测所述触控端的当前电阻信息， 并对所述当前电阻 信息进行处理， 以判断所述触控端与所述触控面之间是否形成人 体闭合电流。 通常， 所述触控端与所述触控面之间所形成的人体 闭合电流越大， 所述触控端的当前电阻信息相对于初始电阻信息 的变化 （减小） 量越大。 例如， 当所述触控端的当前电阻信息相 对于所述初始电阻信息减小， 并且减小量超过 5%时， 判断结果为 所述触控端与所述触控面之间形成人体闭合电流。
当判断出所述触控端与所述触控面之间形成人体闭合电流 时， 所述触控端被判断为与所述触控面有效接触。
然后， 确定所述触控端对所述触控面的具体触控位置， 以确 定相应的触控命令， 并进行相应的触控响应。
当确定了所述触控端没有与所述触控面有效接触后， 可以执 行返回命令以继续监测所述触控端的当前电阻信息。
当然， 穿戴式触控装置可以循环执行上述穿戴式触控方法， 直至该穿戴式触控装置待机或关机。 本实施例中的技术方案通过监测所述触控端与所述触控面之 间是否形成人体闭合电流 /电压， 例如， 通过监测所述触控端的电 阻变化， 来判断所述触控端是否与所述触控面有效触控， 从而保 证了触控的有效性。 实施例 2 :
本实施例提供一种穿戴式触控装置和相应的穿戴式触控方 法， 与实施例 1相比， 本实施例中的监测单元 2除了包括实施例 1 中的电阻信息釆集单元外还包括压力监测单元 （例如压力传感 器） ， 即本实施例中， 所述接触信息还包括接触力度信息， 并且 判断所述触控端是否与所述触控面有效接触还包括： 判断所述接 触力度信息是否有效。
具体地， 所述压力监测单元用于监测所述触控端与所述触控 面之间产生的接触力度信息， 并将所述接触力度信息发送至处理 单元 3。
本实施例中的压力监测单元可以是压力传感器， 例如可以釆 用电阻应变片压力传感器、 半导体应变片压力传感器或压阻式压 力传感器等。 可以理解的是， 所述压力监测单元可以是能够以直 接或间接方法获得压力变化的任何仪器， 优选釆用电阻应变片压 力传感器， 电阻应变片压力传感器的结构简单、 输出精度较高、 线性和稳定性好， 且其价格较低、 购买方便。
处理单元 3包括对比模块和判断模块， 所述处理单元 3内预 存有接触力度阔值信息， 其中， 所述对比模块用于对比所述接触 力度信息和所述接触力度阔值信息， 并将对比结果发送至所述判 断模块， 所述判断模块根据所述对比结果来判断所述接触力度信 息是否有效。 优选的是， 处理单元 3可以釆用微型处理器 （例如 单片机） 实现。
其中，判断所述触控端是否与所述触控面有效接触可以包括： 当判断出所述触控端与所述触控面之间形成人体闭合电流并且所 述接触力度信息有效时， 所述触控端被判断为与所述触控面有效 接触； 当判断出所述触控端与所述触控面之间形成人体闭合电流 但所述接触力度信息无效、 或判断出所述触控端与所述触控面之 间没有形成人体闭合电流时， 所述触控端被判断为没有与所述触 控面有效接触。
在本实施例中， 通过监测所述触控端的电阻变化以及所述触 控端与所述触控面之间的接触力度信息来判断所述触控端是否与 所述触控面有效触控。 在通常情况下， 所述触控端与所述触控面 之间的接触力度越大， 所述触控端的电阻变化 （即减小） 越大。 因此， 通过监测所述触控端的电阻信息和所述触控端与所述触控 面之间的接触力度信息， 可实现触控有效性的判断。
该实施例中， 载体 1仍可以釆用 PVC材料形成。 优选的是， 载体 1能穿戴于人体手指上， 例如被形成为环状， 监测单元 2 (例 如包括电阻传感器和压力传感器）和处理单元 3均可设置于载体 1 中， 例如， 电阻传感器设置于载体 1 的内表层， 以便能更好地感 测作为触控端的人体手指的电阻信息， 压力传感器可设置于任意 适当位置， 只要其能够监测到所述触控端与所述虚拟触控面之间 的接触力度信息即可。
相应地， 本实施例提供一种穿戴式触控方法， 与实施例 1相 比， 该穿戴式触控方法中， 所述接触信息包括接触力度信息， 其 中， 监测所述触控端与所述触控面之间的接触信息的步骤包括： 监测所述触控端与所述触控面之间产生的接触力度信息， 判断所 述触控端是否与所述触控面有效接触的步骤还包括： 判断所述接 触力度信息是否有效。
相应地， 对所述接触信息进行处理的步骤包括： 对比所述接 触力度信息和预存的接触力度阔值信息； 根据对比结果来判断所 述接触力度信息是否有效。
进一步优选的是， 判断所述触控端是否与所述触控面有效接 触的步骤包括： 当判断出所述触控端与所述触控面之间形成人体 闭合电流并且所述接触力度信息有效时 （例如， 当作为接触端的 人体手指的当前电阻信息相对于其初始电阻信息的减小量超过 5% 时， 且所述接触力度信息超过所述接触力度阔值信息 5%时） ， 所 述触控端被判断为与所述触控面有效接触； 当判断出所述触控端 与所述触控面之间形成人体闭合电流但所述接触力度信息无效、 或判断出所述触控端与所述触控面之间没有形成人体闭合电流 时， 所述触控端被判断为没有与所述触控面有效接触。
这里， 可以理解的是， 如果所述触控端与所述触控面之间形 成人体闭合电流， 但所述接触力度信息无效， 则表明所述接触端 (例如人体手指） 只是轻轻擦过所述触控面 （例如人体手掌） ， 即只是意外的触碰， 而非进行有意的触控。 因此， 该情况下， 所 述触控端被判断为没有与所述触控面有效接触， 从而不执行任何 触控响应。
图 4所示为本实施例中的穿戴式触控方法的触控流程图。 该穿戴式触控方法中， 首先， 进行初始化， 例如预存所述触 控端 （例如人体手指） 的初始电阻信息以及接触力度阔值信息。
然后， 监测所述触控端的当前电阻信息、 以及监测所述触控 端与例如为人体手掌的触控面之间的接触力度信息， 并对所述当 前电阻信息和接触力度信息进行处理， 以判断所述触控端是否与 所述触控面有效接触。
例如， 当作为触控端的人体手指意图对作为触控面的人体手 掌进行触控但未真正触摸到人体手掌时， 即， 压力传感器可能会 监测到一定的接触力度， 但是电阻传感器监测到的电阻变化为 0， 该情况下， 人体手指被判断为没有与人体手掌有效接触。 或者， 当压力传感器监测到的接触力度为 0，但是电阻传感器监测到一定 的电阻变化 （可能超过 5% ) 时， 可以理解成， 人体手指可能只是 轻轻擦过人体手掌， 即只是意外的触碰， 而非有意的触控， 此时， 人体手指也被判断为没有与人体手掌有效接触。 只有当压力传感 器监测到的接触力度不为零 （例如， 大于接触力度阔值约 5% ) ， 且电阻传感器监测到一定的电阻变化 （例如， 可能超过 5% ) 时， 才判断出作为触控端的人体手指与作为触控面的人体手掌有效接 触， 从而执行相应的触控响应。
当确定了所述触控端没有与所述触控面有效接触后， 可以执 行返回命令以继续监测所述触控端的当前电阻信息以及所述触控 端与所述触控面之间的接触力度信息。 当然， 穿戴式触控装置可以循环执行上述穿戴式触控方法， 直至该穿戴式触控装置待机或关机。
本实施例中的穿戴式触控装置及相应的穿戴式触控方法的其 他部分与实施例 1中的相同， 这里不再赘述。
在本实施例中， 除了监测所述触控端与所述触控面之间是否 形成人体闭合电流 /电压之外， 还监测所述触控端与所述触控面之 间的接触力度信息， 来判断触控的有效性， 进一步保证了触控的 有效性。 实施例 3 :
本实施例提供一种穿戴式触控装置和相应的穿戴式触控方 法， 与实施例 2相比， 本实施例中的监测单元 2 中包括振动监测 单元来代替压力监测单元， 例如， 所述振动监测单元可以是振动 传感器， 即， 通过所述振动传感器来监测所述触控端与所述触控 面之间产生的接触力度信息 （即， 振动信息） ， 并将所述接触力 度信息发送至处理单元 3， 以进一步判断触控的有效性。
具体地， 在本实施例中， 当所述触控端 （例如人体手指） 敲 击所述触控面 （例如人体手掌） 时， 在通过电阻传感器监测所述 触控端的当前电阻信息的同时， 还通过振动传感器监测所述触控 端敲击所述触控面时在所述触控端与所述触控面之间所产生的接 触力度信息， 然后在处理单元中对所述当前电阻信息和所述接触 力度信息进行处理， 以判断所述触控端是否与所述触控面有效接 触。
更具体地， 当作为触控端的人体手指做出敲击动作或上下晃 动， 但未真正触摸到人体手掌时， 即， 振动传感器会监测到一定 的振动， 但是电阻传感器监测到的电阻变化为 0， 该情况下， 人体 手指被判断为没有与人体手掌有效接触。 或者， 当振动传感器没 有监测到振动， 但是电阻传感器监测到一定的电阻变化 （可能超 过 5% ) 时， 可以理解成， 人体手指可能只是轻轻擦过人体手掌， 即只是意外的触碰， 而非有意的触控， 此时， 人体手指也被判断 为没有与人体手掌有效接触。 只有当振动传感器监测到的振动不 为零 （例如， 大于振动阔值约 5% ) ， 且电阻传感器监测到一定的 电阻变化 （例如， 可能超过 5% ) 时， 才判断出作为触控端的人体 手指与其上形成有虚拟触控面的人体手掌有效接触， 从而执行相 应的触控响应。
本实施例中的穿戴式触控装置的其他部分与实施例 2 中的相 同， 这里不再赘述。
本实施例中的相应的穿戴式触控方法与实施例 2 中的穿戴式 触控方法类同， 这里不再赘述。
本实施例中的穿戴式触控装置和相应的穿戴式触控方法中， 在通过电阻传感器监测所述触控端的电阻信息以判断所述触控端 与所述触控面之间是否形成人体闭合电流 /电压的同时， 还通过振 动传感器来监测所述触控端与所述触控面之间的接触力度信息， 以验证触控的有效性， 更进一步地提高了触控的有效性。 容易理解的是， 监测单元 2 中可以包括能对人体闭合电流 / 电压进行监测、 能实现电阻的定量测量、 对接触力度进行监测的 其他仪器， 而不局限于实施例 1至 3 中所示例的电阻传感器、 压 力传感器或振动传感器， 在不同穿戴对象或触控对象的具体的应 用示例中， 可以进行灵活进行设置和匹配的配置， 这里不做—— 示例。 本发明提供的穿戴式触控装置和相应的穿戴式触控方法中， 当所述触控端为人体部分 （例如人体手指） 且所述触控面为人体 自身的其他区域 （非所述触控端的人体部分， 例如人体手掌） 上 时， 能够通过所述监测单元 （例如， 电阻传感器） 进行监测来判 断所述触控端与所述触控面之间是否形成人体闭合电流 /电压（例 如， 通过监测所述触控端的电阻变化） ， 从而判断所述触控端与 所述触控面之间的接触的有效性； 或者， 进一步监测 （例如通过 压力传感器或振动传感器） 所述触控端与所述触控面之间的接触 力度信息， 以进一步确认所述触控端与所述触控面之间是否有效 接触， 进一步保证了触控的有效性。 该穿戴式触控装置体积小巧、 便于携带， 能有效保证触控的有效性。
而釆用的示例性实施方式， 然而本发明并不局限于此。 对于本领 域内的普通技术人员而言， 在不脱离本发明的精神和实质的情况 下， 可以做出各种变型和改进， 这些变型和改进也视为本发明的 保护范围。
