关于本发明的基本原理, 请参阅图 1所示, 是于一红外线定位触控笔 1 0上 设有一红外线发光二极管 1 1 (I R LED)串接一开关 1 2与一直流电源 1 3 以形成回 路, 当按压开关 12使其导通时即会使红外线发光二极管 1 1 直接连接至直流电 源 1 3, 而令其发出红外线光束, 该红外线光束照射于一资讯揭示幕 20上时, 是 由外部的红外线接收器(图中未示)接收由资讯揭示幕 20 所反射的红外线光束, 通过计算红外线光束反射的位置以产生定位功能; 该资讯揭示幕 20可以是一投 影机的投影幕、 一白板或一不具触控功能的屏幕。
请参阅图 2所示, 是由一主机 30连接一投影机(图中未示)与一红外线接收 器 32 , 主机 30的屏幕 31的画面是通过投影机投射至资讯揭示幕 20上, 于本较 佳实施例中, 该资讯揭示幕 20是投影幕, 该主机 30 可以是一笔记型电脑或一 桌上型电脑; 该主机 30是以有线或无线的方式连接至红外线接收器 32, 用以接 收由资讯揭示幕 20反射的红外线定位触控笔 10所发出的红外线光束, 该红外 线定位触控笔 10 的近笔尖处设有一个红外线发光二极管 11 以朝外发出红外线 光束, 再由红外线接收器 32接收资讯揭示幕 20反射的红外线光束后送至主机 30, 该主机 30将红外线光束的反射点的位置经过计算与转换后, 即可定位红外 线定位触控笔 10是指向资讯揭示幕 20上的哪个位置。
而红外线定位触控笔 10 的定位方式是以红外线定位触控笔 10对准资讯揭 示幕 20上的一游标 21, 再由红外线定位触控笔 10近笔尖处的红外线发光二极 管 11朝向游标 21发出红外线光束, 该资讯揭示幕 20会反射红外线光束, 由红 外线接收器 32接收该反射的红外线光束, 以确认游标 21 的位置, 当红外线定 位触控笔 10在红外线接收器 32 的接收范围内移动红外线光束时, 资讯揭示幕 20上显示的游标 21 即会同步移动, 红外线定位触控笔 10由此可以现有触控面 板的操控方式操作游标 21。
而欲点选资讯揭示幕 20所显示的功能图像(Icon)时, 是通过按压红外线定 位触控笔 10上的开关 12,使与开关 12连接的红外线发光二极管 11产生断续或 开关(ON- OFF)的信号, 如同现有操作触控面板的二次触控点击方式, 以开启欲 执行的功能图像或启动功能图像所代表的功能, 例如开启应用程序, 由于移动 红外线定位触控笔 10时, 资讯揭示幕 20上的游标 21 亦随的同步移动, 因此将 红外线定位触控笔 10放置或靠近于资讯揭示幕 20表面时, 即可产生如触控方 式在资讯揭示幕 20表面书写或绘图的功能。
请参阅图 3所示, 当红外线定位触控笔 10以红外线光束照射资讯揭示幕 20 时, 可能会因为照射角度与位置而产生红外线光束反射角度不足或是遭到使用 者手掌遮蔽的状态, 使得红外线接收器 32无法接收到由资讯揭示幕 20反射的 红外线光束的问题, 请配合参阅图 4 所示, 因此解决的方式是于红外线定位触 控笔 10靠近笔尖的笔身上另设有一红外线发光二极管 11, , 该增设的红外线发 光二极管 11, 是与原本的红外线发光二极管 11呈一夹角设置, 该夹角的角度范 围为 0-180度之间, 实际使用时较佳的夹角角度是介于 45-90度间, 于本较佳 实施例中是以呈 90度的方式垂直设置, 当原本的红外线发光二极管 11 所发出 的红外线光束发生反射角度不足或遮蔽的问题时, 可由与其呈 90度夹角设置的 红外线发光二极管 11, 朝向红外线接收器 32发出红外线光束, 解决因反射角度 不足或遮蔽使得红外线接收器 32无法接收到资讯揭示幕 20反射红外线光束的 问题。
关于本发明的第一较佳实施例, 请参阅图 5、 6所示, 该红外线定位触控笔 10 包含有一操作模块 14、 一红外线模块 15、 一微控制器 16、 一红外线控制模 块 17、 一电源模块 18与一可调色光发光模块 19, 其中,
该操作模块 14 包含有两个定位按键 141与多数个以上的功能按键 142, 该 等定位按键 141是分别与电源模块 18 以及红外线模块 15 电连接且形成并联, 该等功能按键 142是与微控制器 16电连接, 各按键是分别代表一种操作功能且 由微控制器 16产生对应该功能的一操作讯号; 于本较佳实施例中, 该等功能按 键 142代表的功能可以是一鼠标左键、 一鼠标左键、 一往上页(Page Up)、 一往 下页(Page Down)、 一往左页(Page Left) . 一往右页(Page Right)、 一取消 (Escape) , 一清除(Abo r t )或是一橡皮擦擦拭(E r a s e r )以增加红外线定位触控笔 10使用的方便性。
该红外线模块 15包含有两红外线发光二极管 151, 其与红外线控制模块 17 电连接以发出红外线讯号; 如图 5所示, 该等红外线发光二极管 151 是相互并 联, 又如图 6所示, 该等红外线发光二极管 151是相互串联。
该微控制器 16是与电源模块 18以及红外线控制模块 17电连接, 该微控制 器 16接收操作模块 14的功能按键 142的操作讯号以驱动红外线控制模块 17发 出红外线讯号。
该红外线控制模块 17是与红外线模块 15电连接, 微控制器 16依据功能按 键 142产生对应的操作讯号, 再由红外线控制模块 17依据该操作讯号驱动红外 线模块 15, 或是由红外线控制模块 17依据该操作讯号进行编码, 经编码后的讯 号再由红外线模块 15发出红外线光束; 于本较佳实施例中, 红外线控制模块 17 与红外线模块 15之间串接有一二极管, 避免使用定位按键 141时, 电源模块 18 的电源逆流至红外线控制模块 17。
该电源模块 18是与微控制器 16以及红外线模块 15电连接, 用以提供微控 制器 16与红外线模块 15所需电力。
该可调色光发光模块 19是与微控制器 16 电连接, 其包含有多数个发光二 极管以产生可混合调色的光, 该操作模块 14的功能按键 142包含有一可调色光 按键, 微控制器 16接收操作模块 14 的可调色光按键被按压后的的操作讯号, 以控制可调色光发光模块 19组合发出的不同颜色的可调色光; 于本较佳实施例 中,该等发光二极管发出的红光、蓝光与绿光经混合调色可产生七彩颜色的光, 可直接切换并对应现有利用不同颜色的色笔于资讯揭示幕 20表面书写文字、 画 线或绘图功能。
使用者通过操作模块 14送出操作讯号给微控制器 16, 微控制器 16依据功 能按键 142的操作讯号驱动红外线控制模块 17发出对应该操作讯号的红外线光 束, 或是由定位按键 141驱动红外线模块 1 5送出对应定位讯号的红外线光束, 由外部的一红外线接收器 22 (图中未示)接收该等红外线光束的讯号以进行定位 与操作功能解析。
关于本发明的第二较佳实施例, 请参阅图 7、 8所示, 该微控制器 16连接 有一无线模块 17A, 该无线模块 19是用以取代前述的红外线控制模块 17 , 微控 制器 16将该等功能按键 142的操作讯号经由无线模块 19转换为无线讯号并向 外发射, 由一无线接收模块(图中未示)接收该无线讯号后以进行操作功能解析; 于本较佳实施例中, 该无线模块 17A 可以是使用蓝牙(B l ue Too th)传输介面、 无线电射频信号(Rad i o Frequency)传输介面或是无线网路(Wi F i )传输介面; 如 图 7所示, 该等红外线发光二极管 1 51是相互并联, 又如图 8所示, 该等红外 线发光二极管 151是相互串联。
请参阅图 9 所示, 为本发明的第一较佳实施例的基本结构图, 红外线定位 触控笔 1 0于其笔身内设有一个定位按键 141,该定位按键 141与电源模块 18电 连接以提供红外线发光二极管 151 电力, 又使用者在使用红外线定位触控笔 10 时, 需以手指按压笔身上的定位按键 141, 但是当使用者长时间持续按压定位按 键 141时, 易造成该使用者手部不适, 为避免使用者长时间按压定位按键 141, 是于红外线定位触控笔 1 0的笔尖内设置另一定位按键 141, 并以连杆的方式突 出于笔尖, 使用者以手掌握持红外线定位触控笔 1 0时, 可于资讯揭示幕 20表 面移动或书写, 或以点选方式启动图像功能, 以连杆推动定位按键 141 并产生 定位讯号。
请参阅图 1 0所示, 为本发明的第一较佳实施例的另一基本结构图, 由于红 外线定位触控笔 1 0本身不具颜色标示功能, 因此在资讯揭示幕 20表面移动或 书写线条或文字时, 并无法变更线条或文字的颜色, 因此红外线定位触控笔 1 0 内的可调色光发光模块 19设有一红色发光二极管 191、 一蓝色发光二极管 192 与一绿色发光二极管 193, 该等发光二极管发出的红光、 蓝光与绿光的单色光经 由混合调色后可产生七彩颜色; 令使用者易于辨识选择的线条或文字的颜色。 请参阅图 1 1所示, 为本发明的第二较佳实施例的基本结构图, 红外线定位 触控笔 1 0于其笔身内设有无线模块 1 7 A,微控制器 1 6将该等功能按键 142的操 作讯号通过无线模块 1 7A转换为无线讯号并向外发射, 由一无线接收模块(图中 未示)接收该无线讯号后传送至主机 30, 以进行操作功能解析。
由上述可知, 红外线定位触控笔 1 0接近资讯揭示幕 20时令其发出红外线 光束对准游标 21, 使红外线接收器 22接收资讯揭示幕 20反射的红外线讯号并 进行定位, 使其适用于各种大小尺寸的资讯揭示幕 20以操作游标或点选功能图 像, 不需于资讯揭示幕 20上设置触控面板, 解决大尺寸触控屏幕的制作技术复 杂与成本高昂的问题, 并可解决现有投影幕或白板无法使用触控功能而造成使 用不便的问题。
