- the embodiment of the present application also provides a contact infrared touch method, which is applied to the above-mentioned contact infrared touch device.
- the contact infrared touch control method includes:
- Step S10 when it is detected based on the infrared signal that there is a touch object at a preset height on the touch panel, detecting position information of the touch object based on the infrared signal according to a preset period to obtain a first touch point position set;
- the infrared signal is emitted and received by the infrared detection element 2 of the contact infrared touch device. Since the infrared detection element 2 itself has a certain size, and the touch panel 1 has a certain deformation due to the processing technology and the physical properties of the material, in order to prevent the infrared signal from being blocked by the deformation of the touch panel 1, there is a certain distance between the infrared signal and the touch panel 1, that is, a preset height. At the preset height position on the touch panel, a detection network composed of infrared signals is scattered.
- the touch object when the touch object approaches the touch panel and reaches a preset height and contacts the detection network, the touch object is detected at the preset height on the touch panel; the infrared signal is detected based on a preset period, so the position information of the touch object is detected according to the preset period, and the position information obtained by the detection is recorded as the first touch point position set.
- the first touch point position set can be recorded in the form of a queue, and each position information is placed in the queue in order according to the detection time.
- Step S20 during the first contact point position set detection process, detecting whether there is a contact signal on the touch panel;
- the distance between the touch object and the touch panel is less than or equal to the preset height, and the contact sensor is used to detect whether there is a contact signal on the touch panel, so as to determine whether the touch object contacts the touch panel after passing through the infrared signal detection network.

- the first contact point position set includes a number of position information of the touch object from reaching a preset height to contacting the touch panel.
- the position information in the first contact point position set whose detection time and current time interval are less than the preset time is determined as the target contact point position.
- the target contact point is the actual contact point between the touch object and the touch panel identified by this method.
- the preset time can be used to limit the time when the contact signal is detected and the limited position information detected within the previous preset time, from which the target contact point position is selected; at the same time, the preset time can be used to exclude the contact points that are too far away from the actual contact time to prevent the target contact point position from being incorrectly identified.
- the target contact point position is displayed on the touch panel, that is, the first contact point where the touch object contacts the touch panel is displayed.
- a contact infrared touch method proposed in an embodiment of the present application utilizes an infrared signal.

- the touch panel is simultaneously detected to determine whether there is a contact signal.
- the contact signal is detected, it is determined that the touch object is in contact with the touch panel, and then the position information in the first contact position set whose interval between the detection time and the current moment is less than the preset time is determined as the target touch position.
- the position information that meets this condition belongs to the position information obtained by detection close to the current moment, which can reflect the actual contact position between the touch object and the touch panel, and the position information is displayed on the touch panel as the target touch position.
- the infrared signal detects a touch object
- only the first contact point position set is recorded, and the target contact point position is determined in the first contact point set after the contact signal when the touch object actually contacts the touch panel is detected. This allows the target contact point position to be close to the actual contact point when the contact object contacts the touch panel, thereby improving the accuracy of the displayed contact points and writing handwriting, and improving the writing experience.
- the step of detecting whether there is a touch signal on the touch panel includes:
- An image signal of the touch panel is acquired and a target image signal is detected in the image signal, wherein the contact signal includes the target image signal, and the target image signal indicates that the touch object is in contact with the touch panel.
- the vibration signal or sound characteristic signal can be used as a contact signal for judging contact, and the corresponding contact sensor can be a vibration sensor or a sound sensor.
- the contact sensor can also be set as a camera, and the camera is used to obtain the image signal of the touch panel, so as to monitor whether the touch object is in contact with the touch panel.
- the contact signal is a target image signal that monitors the contact between the touch object and the touch panel.
- vibration signals By using vibration signals, sound signals or image signals, a variety of methods can be used to accurately determine whether the touch object is in contact with the touch panel, thereby improving the accuracy of determining the contact moment, thereby making the target touch point position closer to the actual touch point position, and improving the accuracy of the displayed touch point and writing handwriting.
- the contact infrared touch control method further includes:
- step S10 is executed.
- the infrared signal sent and received by the infrared detection element 2 is not blocked, and the state of the infrared signal received at this time can be determined as the preset signal.
- the infrared signal does not match the preset signal, it can be determined that the infrared signal is blocked, that is, the touch object reaches the preset height, and step S10 is executed.
- the received infrared signal is weaker than when it is not blocked by the touch object, so the signal strength can be used as a criterion for judging whether the infrared signal matches the preset signal.
- step S30 includes:
- Step S31 when the contact signal is detected, determine that the interval between the detection time and the current time in the first contact position set is less than the preset time, and the position information with the smallest interval time is the target contact position, and display the target contact position on the touch panel.
- the moment when the contact signal is detected in the first contact position set and the limited position information detected within the previous preset time period can be limited by a preset time period, from which the position information with the shortest interval with the current moment can be determined as the target contact position, which is generally the position information corresponding to the moment when the touch object contacts the touch panel, or the closest position information before the moment of contact.
- the selected target touch point position can be made as close as possible to the actual contact point between the touch object and the touch panel, so that the written handwriting begins to be displayed at the target touch point position close to the actual contact point, thereby improving the accuracy of the displayed touch point and the written handwriting.
- step S30 the following steps are further included:
- a corresponding track is displayed on the touch panel according to the second touch point position set.
- the target touch point position is the first touch point between the touch object and the touch panel
- the user since the target touch point position is the first touch point between the touch object and the touch panel, in actual usage scenarios, the user generally also controls the touch object to slide on the touch panel to achieve writing on the touch panel. Therefore, it is also necessary to display the writing trajectory based on the touch points generated after the target touch point position.
- the contact signal includes a vibration signal, a sound signal or an image signal, all of which are signals for determining whether the touch object and the touch panel have switched from a non-contact state to a contact state.
- a vibration signal a sound signal or an image signal
- the trajectory can be determined directly based on the position information of the touch object detected by the infrared signal.
- the infrared signal is continued to be used to detect the position information of the touch object according to a preset period, and the detected position information is continuously recorded as a second touch position set; at the same time, some position information is displayed as a track on the touch panel according to the position information in the second touch position set.
- the second contact position set can be set as a position information queue, and whenever new position information is detected, the position information is added to the end of the queue. At the same time, when it is detected that there is new position information added to the position information queue, the position information is displayed on the touch panel, thereby forming a track of the touch point. Based on the design of the queue, the newly added position information in the set or queue can be directly determined and displayed on the touch panel, and other recorded position information will not interfere. Therefore, the second contact position set can also be designed as the same set as the first contact position set.
- the writing trajectory of the touch object controlled by the user on the touch panel can be displayed, thereby improving the writing experience.
- Figure 5 is a schematic diagram of an application example.
- the position of the dotted line represents the preset height
- the direction of the arrow represents the horizontal movement direction of the touch object, and from left to right, the touch object is above the preset height, reaches the preset height, contacts the touch panel, and slides after contact.
- the four states are defined as state 1, state 2, state 3, and state 4.
- state 1 the touch object is higher than a preset height, and the position information of the touch object cannot be detected at this time; when transitioning to state 2, the touch object reaches the preset height and position information 1 is detected.
- position information 1 is recorded in the first contact position set; when transitioning to state 3, the touch object is detected to be in contact with the touch panel through the contact signal, and position information 2 is also detected at this time.
- the first contact position set includes position information 1 and position information 2, and position information 2 is determined as the target touch position and displayed on the touch panel; when transitioning to state 4, position information 3 of the touch object is detected at this time, and the touch object has slid from the position of position information 2 to the position of position information 3.
- Position information 3 is recorded in the second contact position set, and the trajectory from position information 2 to position information 3 is displayed.
- the method further includes:
- the track is stopped from being displayed.
- the infrared signal when used to detect that there is no touch object at a preset height on the touch panel, it is determined that the touch object is no longer in contact with the touch panel and the distance between the touch object and the touch panel is greater than the preset height.
- the preset signal is the infrared signal that should be received when there is no touch object at the preset height so that the infrared signal is not blocked. Therefore, if the received infrared signal changes from not matching the preset signal to matching the preset signal, it can be determined that there is no touch object at the preset height.
- the touch object is a stylus
- the user has finished writing and has lifted the stylus away from the touch panel, so the track is stopped from being displayed according to the touch point position set.
- the touch point position set is cleared to prevent interference in determining the target touch point position when the touch object contacts the touch panel next time.
- step S10 the method further includes:
- Step S200 determining the amount of position information in the first contact position set
- the touch object used by the user can be various types of objects, such as a stylus or the user's finger.
- the touch object is the user's finger
- the contact signal cannot be triggered when the finger touches the touch panel, that is, the contact signal cannot be used to determine whether the finger is in contact with the touch panel. Therefore, the method of this embodiment is proposed.
- the amount of position information therein is determined, and whether the touch object has touched the touch panel but cannot trigger a touch signal can be determined based on the amount of position information.
- Step S300 when the number of position information is greater than a preset number, determine that the interval between the detection time and the current time in the first contact position set is less than the preset time, and the position information with the smallest interval time is the target contact position, and display the target contact position on the touch panel.
- a preset number is set, and when the number of position information in the first contact point position set is greater than the preset number, it is determined that the touch object has contacted the touch panel, and the preset number can be set in combination with a preset period, for example, the preset number is set to 30.
- the target contact point position is determined from the first contact point position set, and the target contact point position is displayed on the touch panel.
- the step of judging whether the touch object is in contact with the touch panel by the amount of position information in the present embodiment can be used in combination with the step of judging whether the touch object is in contact with the touch panel by the contact signal in the above embodiment.
- the target contact point position can be displayed and the subsequent step of displaying the trajectory can be continued, and the judgment on whether the touch object is in contact with the touch panel will not be repeated.
- determining whether the touch object is in contact with the touch panel can avoid the situation where it is impossible to determine whether the touch object is in contact with the touch panel through the contact signal alone. This allows users to use multiple types of touch objects to write on the touch panel, improving the stability of touch judgment and thus improving the writing experience.
- step S30 includes:
- Step S32 when more than one contact signal is detected, determining the earliest detection time among all detection times corresponding to the more than one contact signal as the target time;
- more than one contact sensor may be provided. Meanwhile, in actual application scenarios, there may be multi-point touch by the user, and the above situations will result in the detection of more than one contact signal.
- the contact signal with the earliest detection time is determined as the signal indicating that the touch object actually contacts the touch panel, and the corresponding detection time of the contact signal is determined as the target time.
- Step S33 determining that the position information in the first contact position set that meets preset conditions is the target contact position, wherein the preset conditions include that the interval between the detection time of the position information and the current time is less than a preset time, and the detection time of the position information matches the target time.
- the interval between the detection time and the current time in the first touch position set is less than a preset time, and the position information matching the target time is the target touch position, and the target touch position is displayed on the touch panel.
- the judgment of whether the touch object contacts the touch panel is performed only once, and when it is determined that contact has occurred, the trajectory is displayed according to the detected position information.
- the infrared signal since the infrared signal repeatedly detects the position information according to a preset period, the writing trajectory of multiple points can still be restored in the actual use scenario.
- the contact signal with the earliest corresponding detection time from more than one contact signal is only used to determine the target touch point position (i.e. the first displayed touch point), and will not interfere with the trajectory judgment and display in the case of multiple touch points.
- the contact signal with the earliest corresponding detection time among more than one contact signals as the contact signal for determining the target contact point position, it is possible to accurately determine the moment when the touch object contacts the touch panel in the case of multi-touch or multiple contact sensors, thereby avoiding the occurrence of confusion in the determination or display of contacts or trajectories, and improving the accuracy of the displayed contacts and writing handwriting.
- an embodiment of the present application further provides a storage medium, on which a contact infrared touch program is stored.

本申请目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
本申请实施例提出一种接触式红外触控设备。参照图1，接触式红外触控设备包括触控面板1、红外检测元件2、接触传感器3和控制装置4，触控面板1用于提供给用户进行触控操作及输出显示数据；红外检测元件2用于检测触控面板上方预设高度是否存在触控物，红外检测元件包括有发射红外信号的LED单元以及接收红外信号的红外接收单元，当两个单元之间传输的红外信号被触控物遮挡时，即可根据红外信号的变化检测出存在触控物，图1中的虚线箭头即表征红外信号；接触传感器3用于检测触控物与触控面板接触时的接触信号；控制装置4分别与触控面板1、红外检测元件2和接触传感器3连接并进行控制。需要说明的是，图1仅为接触式红外触控设备的一种示意图，图1中示出的结构并不构成对接触式红外触控设备的限定。
如图2所示，控制装置4可以包括：处理器1001，例如中央处理器（Central
Processing Unit，CPU），存储器1002。其中，存储器1002可以是高速的随机存取存储器（Random
Access Memory，RAM）存储器，也可以是稳定的非易失性存储器（Non-Volatile Memory，NVM），例如磁盘存储器。存储器1002可选的还可以是独立于前述处理器1001的存储装置。
本领域技术人员可以理解，图2中示出的结构并不构成对接触式红外触控设备的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
如图2所示，作为一种存储介质的存储器1002中可以包括接触式红外触控程序。在图2所示的接触式红外触控设备中，处理器1001调用存储器1002中存储的接触式红外触控程序，并执行本申请实施例提供的接触式红外触控方法。
本申请实施例还提供了一种接触式红外触控方法，应用于上述接触式红外触控设备。
参照图3，提出本申请接触式红外触控方法一实施例。在本实施例中，所述接触式红外触控方法包括：
步骤S10，当基于红外信号检测到触控面板上的预设高度存在触控物时，按照预设周期基于所述红外信号检测所述触控物的位置信息，获得第一触点位置集合；
红外信号由接触式红外触控设备的红外检测元件2进行发射和接收，由于红外检测元件2本身具有一定的大小，且触控面板1因为加工工艺和材料物理性质等原因具有一定的形变，为了红外信号不被触控面板1的形变遮挡，红外信号与触控面板1之间间隔有一定的距离，即预设高度，在触控面板上的预设高度位置，散布有红外信号构成的探测网。
在一实施例中，当触控物接近触控面板，达到预设高度与探测网接触时，即检测到触控面板上预设高度存在触控物；红外信号基于预设周期进行检测，因此按照预设周期检测触控物的位置信息，并将检测获得的位置信息记录为第一触点位置集合。此外，第一触点位置集合可通过队列的形式进行记录，每个位置信息根据检测时间按顺序放入队列中。
步骤S20，在所述第一触点位置集合检测过程中，检测所述触控面板是否存在接触信号；
在一实施例中，当第一触点位置集合开始记录触控物的位置信息时，此时触控物与触控面板之间的距离小于或等于预设高度，利用接触传感器检测触控面板是否存在接触信号，从而确定触控物穿过红外信号的探测网后是否与触控面板接触。
步骤S30，当检测到所述接触信号时，确定所述第一触点位置集合中检测时间与当前时刻间隔时长小于预设时长的位置信息为目标触点位置，并在所述触控面板显示所述目标触点位置。
在一实施例中，当利用接触传感器检测到接触信号时，确定触控物与触控面板接触，此时第一触点位置集合中包括触控物由达到预设高度至接触触控面板过程中的若干位置信息，确定第一触点位置集合中检测时间与当前时刻间隔时长小于预设时长的位置信息为目标触点位置，目标触点位置即为本方法认定的触控物与触控面板的实际接触触点，利用预设时长可限定检测到接触信号的时刻及之前预设时长内检测到的有限个位置信息，从中挑选目标触点位置；同时，利用预设时长可排除与实际接触的时刻相隔太远的触点，防止错误认定目标触点位置。确定目标触点位置后，在触控面板显示目标触点位置，即显示触控物与触控面板接触的第一个触点。
本申请实施例提出的一种接触式红外触控方法，该方法利用红外信号，当检测到触控面板上的预设高度存在触控物时，按照预设周期检测触控物的位置信息，将位置信息记录为第一触点位置集合；然后，在检测记录第一触点位置集合的过程中，同时检测触控面板是否存在接触信号；当检测到所述接触信号时，确定触控物与触控面板发生接触，继而确定第一触点位置集合中检测时间与当前时刻间隔时长小于预设时长的位置信息为目标触点位置，满足该条件的位置信息属于与当前时刻相近的检测获得的位置信息，可反映触控物与触控面板的实际接触位置，将该位置信息作为目标触点位置在触控面板显示。相比于目前直接基于触控面板上方的红外信号直接判断接触和显示触点，当红外信号检测到触控物时只记录第一触点位置集合，等待检测到触控物与触控面板实际接触时的接触信号后再在第一触点位置集合中确定目标触点位置，可使目标触点位置贴近接触物与触控面板接触时的实际触点，从而提高显示的触点和书写笔迹的准确性，提高书写体验。
进一步的，在本实施例中，检测所述触控面板是否存在接触信号的步骤包括：
检测所述触控面板是否存在震动信号，所述接触信号包括所述震动信号；或，
检测所述触控面板是否存在被接触时产生的声音特征信号，所述接触信号包括所述声音特征信号；或，
获取所述触控面板的图像信号并检测所述图像信号是否存在目标图像信号，所述接触信号包括所述目标图像信号，所述目标图像信号表征所述触控物与所述接触面板接触。
由于触控物是根据一定的速度下落与触控面板接触，实际接触时将产生一定的碰撞，从而发出一定的震动信号或声音特征信号，因此可利用震动信号或声音特征信号作为判断接触的接触信号，对应的接触传感器可分别为震动传感器或声音传感器。此外，接触传感器也可设置为摄像头，利用摄像头获取触控面板的图像信号，从而监控触控物与触控面板之间是否接触，此时接触信号为监控到触控物与触控面板接触的目标图像信号。
利用震动信号、声音信号或图像信号，可利用多种途径精准判断触控物是否与触控面板发生接触，提高判断接触时刻的精准性，从而使目标触点位置更贴近实际触点位置，提高显示的触点和书写笔迹的准确性。
进一步的，在本实施例中，所述接触式红外触控方法还包括：
当检测到所述触控面板上所述预设高度的所述红外信号与预设信号不匹配时，确定所述预设高度存在所述触控物，执行步骤S10。
在一实施例中，当触控面板上预设高度不存在触控物时，红外检测元件2发送和接收的红外信号不被遮挡，可将此时接收到的红外信号的状态确定为预设信号。当检测到红外信号与预设信号不匹配时，即可判断红外信号被遮挡，即触控物达到预设高度，执行步骤S10。此外，当红外信号被触控物遮挡时，被接收到的红外信号相比于不被触控物遮挡时较弱，因此可利用信号强度作为判断红外信号与预设信号是否匹配的标准。
通过比对接收到的红外信号与预设信号是否匹配，可在触控物接近触控面板至预设高度时及时判断，从而实现本实施例的接触式红外触控方法，提高书写体验。
进一步的，基于上述实施例，提出本申请接触式红外触控方法另一实施例。在本实施例中，参考图4，步骤S30包括：
步骤S31，当检测到所述接触信号时，确定所述第一触点位置集合中所述检测时间与当前时刻间隔时长小于所述预设时长，且所述间隔时长最小的位置信息为所述目标触点位置，并在所述触控面板显示所述目标触点位置。
在一实施例中，通过预设时长可限定第一触点位置集合中检测到接触信号的时刻及之前预设时长内检测到的有限个位置信息，从中可确定与当前时刻间隔时长最小的位置信息为目标触点位置，一般即为触控物与触控面板接触的时刻对应的位置信息，或接触的时刻之前最接近的位置信息。
通过预设时长和与当前时刻间隔时长最小的两个条件，可使挑选的目标触点位置尽可能贴近触控物与触控面板的实际接触触点，从而在贴近实际接触触点的目标触点位置开始显示书写的笔迹，提高显示的触点和书写笔迹的准确性。
进一步的，在本实施例中，步骤S30之后，还包括：
按照所述预设周期基于所述红外信号检测所述触控物的位置信息，获得第二触点位置集合；
根据所述第二触点位置集合在所述触控面板显示对应的轨迹。
在显示目标触点位置后，由于目标触点位置为触控物与触控面板接触的第一个触点，而在实际使用场景中，用户一般还操控触控物在触控面板上滑行，从而实现在触控面板上书写，因此还需根据目标触点位置之后产生的触点显示书写的轨迹。
基于上述实施例，接触信号包括震动信号、声音信号或图像信号，其均为判断触控物与触控面板由不接触状态切换为接触状态的信号，一般触控物保持与触控面板接触并滑行时，不会产生可触发接触信号的碰撞，因此在显示目标触点位置后可直接根据红外信号检测到的触控物的位置信息确定轨迹。
在一实施例中，显示目标触点位置后，继续利用红外信号按照预设周期检测触控物的位置信息，并持续根据检测到的位置信息记录为第二触点位置集合；同时，根据第二触点位置集合中的位置信息在触控面板将若干位置信息显示为轨迹。
在其他实施例中，第二触点位置集合可设置为一个位置信息队列，每当检测到新的位置信息则将该位置信息方式添加至队列末尾，同时当检测到位置信息队列有新加入的位置信息时，则将该位置信息显示于触控面板，从而构成触点的轨迹。基于队列的设计，可直接确定集合或队列中新增的位置信息并将其显示于触控面板，记录的其他位置信息并不会产生干扰，因此第二触点位置集合也可与第一触点位置集合设计为同一集合。
通过在触控物与触控面板接触后持续检测触控物的位置信息，并在触控面板对应显示其构成的轨迹，从而实现对用户操控触控物在触控面板上书写轨迹的显示，提高书写体验。
示例性的，结合上述实施例，参考图5，图5为应用示例示意图。其中，虚线的位置表征预设高度，该箭头的方向表征触控物的水平运动方向，从左到右依次为触控物在预设高度以上，到达预设高度，与触控面板接触，以及接触后滑行的四个状态，依次定义四个状态为状态1，状态2，状态3以及状态4。当处于状态1时，触控物高于预设高度，此时检测不到触控物的位置信息；过渡到状态2时，触控物到达预设高度，检测到位置信息1，此时第一触点位置集合中记录有位置信息1；过渡到状态3时，通过接触信号检测到触控物与触控面板接触，此时还检测到位置信息2，则此时第一触点位置集合中包括位置信息1和位置信息2，确定位置信息2为目标触点位置并显示于触控面板；过渡到状态4时，检测到触控物此时的位置信息3，触控物已从位置信息2的位置滑动到位置信息3的位置，将位置信息3记录到第二触点位置集合中，并显示从位置信息2至位置信息3的轨迹。
进一步的，在本实施例中，所述根据所述第二触点位置集合在所述触控面板显示对应的轨迹的步骤之后，还包括：
当基于所述红外信号检测到所述触控面板上所述预设高度不存在所述触控物时，停止显示所述轨迹。
在一实施例中，当利用红外信号检测到触控面板上预设高度不存在触控物时，确定此时触控物已经不与触控面板接触，并且触控物与触控面板之间的距离已大于预设高度。
基于上述实施例，当红外信号与预设信号不匹配时，表征预设高度存在触控物，而预设信号即为在预设高度不存在触控物，使红外信号不被遮挡时应该接收到的红外信号，因此若接收到的红外信号从与预设信号不匹配变更为与预设信号匹配时，可确定预设高度已不存在触控物。
在实际应用场景中，例如触控物为触控笔，则为用户完成书写将触控笔提起远离触控面板的状态，因此此时停止根据触点位置集合显示轨迹。此外，将触点位置集合清空，防止对下一次触控物与触控面板接触时对确定目标触点位置产生干扰。
通过检测接收到的红外信号是否重新与预设信号匹配，判断触控物是否停止与触控面板接触，从而停止显示轨迹，提高显示的触点和书写笔迹的准确性。
进一步的，基于上述实施例，提出本申请接触式红外触控方法又一实施例。在本实施例中，参考图6，步骤S10之后，还包括：
步骤S200，确定所述第一触点位置集合中的位置信息数量；
需要说明的是，用户使用的触控物可为多种类型的物体，例如可以是触控笔或用户的手指，而当触控物为用户的手指时，由于手指与触控笔的物理性质差异，手指与触控面板接触时可能存在无法触发接触信号的情况，即无法利用接触信号判断手指是否与触控面板接触，因此提出本实施例的方法。
在一实施例中，在第一触点位置集合中开始记录位置信息后，确定其中的位置信息数量，可根据位置信息数量判断是否为触控物已与触控面板接触却无法触发接触信号的情况。
步骤S300，当所述位置信息数量大于预设数量时，确定所述第一触点位置集合中所述检测时间与当前时刻间隔时长小于所述预设时长，且所述间隔时长最小的位置信息为所述目标触点位置，并在所述触控面板显示所述目标触点位置。
在一实施例中，设置预设数量，当第一触点位置集合中的位置信息数量大于预设数量时，确定触控物已经与触控面板接触，预设数量可结合预设周期进行设置，例如，预设数量设置为30。当通过位置信息数量与预设数量比对确定触控物与触控面板接触时，即从第一触点位置集合中确定目标触点位置，并在触控面板显示目标触点位置。
需要说明的是，本实施例中通过位置信息数量判断触控物是否与触控面板接触的步骤，可与上述实施例的通过接触信号判断触控物是否与触控面板接触的步骤结合使用，当其中一个方法符合条件判断触控物与触控面板接触后，即可显示目标触点位置并继续执行后续显示轨迹的步骤，并不会重复判断触控物与触控面板接触。
通过位置信息数量与预设数量比对确定触控物是否与触控面板接触，可避免单独通过接触信号无法判断触控物与触控面板接触的情况出现，使用户可以使用多种类型的触控物在触控面板上书写，提高触控判断的稳定性，从而提高书写体验。
进一步的，基于上述实施例，提出本申请接触式红外触控方法再一实施例。在本实施例中，参考图7，步骤S30包括：
步骤S32，当检测到多于一个所述接触信号时，确定多于一个所述接触信号中对应所有检测时间中最早的检测时间为目标时刻；
在本实施例中，为了提高接触信号的可靠性，可设置多于一个接触传感器，同时，在实际应用场景中，存在用户多点触控的情况，上述情况均会导致检测到多于一个接触信号。
在一实施例中，当检测到多于一个接触信号时，确定其中检测时间最早的接触信号为触控物实际与触控面板接触的信号，并确定该接触信号的对应检测时间为目标时刻。
步骤S33，确定所述第一触点位置集合中满足预设条件的所述位置信息为所述目标触点位置，所述预设条件包括所述位置信息的检测时间与当前时刻间隔时长小于预设时长，且所述位置信息的检测时间与所述目标时刻匹配。
在一实施例中，确定第一触点位置集合中检测时间与当前时刻间隔时长小于预设时长，且与目标时刻匹配的位置信息为目标触点位置，并在触控面板显示目标触点位置。
需要说明的是，基于上述实施例，在一次触控物落下与触控面板接触，至触控物远离触控面板的过程中，针对触控物与触控面板接触的判断仅进行一次，当确定发生接触后，即根据检测到的位置信息显示轨迹。而针对多点触控的情况，由于红外信号按照预设周期反复进行位置信息的检测，在实际使用场景中依然可以还原多点的书写轨迹，从多于一个接触信号中确定对应检测时间最早的接触信号只用于确定目标触点位置（即第一个显示的触点），并不会对多个触点情况下的轨迹判断和显示产生干扰。
通过将多于一个接触信号中的对应检测时间最早的接触信号作为确定目标触点位置的接触信号，可实现在多点触控或多个接触传感器的情况下对触控物与触控面板接触时刻的准确确定，避免该情况下触点或轨迹确定或显示错乱的情况发生，提高显示的触点和书写笔迹的准确性。
此外，本申请实施例还提出一种存储介质，所述存储介质上存储有接触式红外触控程序，所述接触式红外触控程序被处理器执行时实现如上接触式红外触控方法任一实施例的相关步骤。
需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者系统不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者系统所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者系统中还存在另外的相同要素。
上述本申请实施例序号仅仅为了描述，不代表实施例的优劣。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到上述实施例方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本申请的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在如上所述的一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本申请各个实施例所述的方法。
以上仅为本申请的优选实施例，并非因此限制本申请的专利范围，凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本申请的专利保护范围内。
