为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分的实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本申请保护的范围。
需要说明的是，本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
根据本申请实施例的一个方面，提供了一种交互控制方法，可选地，作为 一种可选的实施方式，上述交互控制方法可以但不限于应用于如图1所示的环境中。用户102可以对触摸板104执行触摸操作，主机106在获取到触摸板104接收到的触摸操作后，识别触摸操作，并根据识别结果生成交互请求。主机106通过交互请求控制投影器108投影出的全息投影虚拟角色110执行与交互请求匹配的交互动作。在此设备中，电池112用于给整个设备供电。
需要说明的是，图1仅为一种硬件结构的示例，并不构成对本实施例的限定。触摸板104与投影器108可以单独出现。此时，触摸板104通过与触摸板104相连的信号发送设备向主机106发送触摸信号。投影器108通过信号接收装置从主机106接收所要投影的交互动作。
需要说明的是，在相关技术中，在使用全息投影设备呈现全息投影虚拟角色时，通常是使用客户端或者语音指令与全息投影设备进行互动。然而，上述与全息投影设备进行互动的方法控制指令单一，全息投影设备仅仅能够进行简单的响应。而本实施例中，采用了通过触摸板获取触摸操作，并对触摸操作进行识别，根据识别出的触摸操作生成交互请求，并根据交互请求执行与交互请求匹配的交互动作的方法，在上述方法中，由于可以直接通过触摸板接收到的触摸操作对全息投影设备进行控制，从而丰富了对全息投影设备进行控制的指令，提高了与全息投影虚拟角色进行互动的灵活性。
为了便于理解和解释本申请实施例提供的交互控制方法，下面结合图2进行说明。其中，本申请实施例提供的交互控制方法可以应用于全息投影设备；而且，作为一种可选的实施方式，该交互控制方法可以包括：
S202，全息投影设备识别对触摸板所执行的触摸操作，其中，全息投影设备用于呈现全息投影虚拟角色；触摸板设置于所述全息投影设备上。
S204，全息投影设备根据识别出的触摸操作生成交互请求，其中，交互请求用于请求与全息投影虚拟角色进行互动；
S206，全息投影设备控制全息投影虚拟角色执行与交互请求相匹配的交互动作。
可选地，上述交互控制方法可以但不限于应用于与全息投影设备中的全息投影虚拟角色进行互动的过程中。例如，上述交互控制方法可以应用于与投影出的全息虚拟动漫人物进行互动的过程中，也可以应用于与投影出的全息虚拟 建筑进行互动的过程中。
为了便于理解和解释，以下以将交互控制方法应用到与全息投影设备投影出全息虚拟动漫人物进行互动的过程为例进行说明。在全息投影设备投影出全息虚拟动漫人物时，用户可以观察到全息虚拟动漫人物。此时，在用户通过触碰触摸板产生触摸操作之后，全息投影设备通过识别该触摸操作并生成交互请求，并根据该交互请求控制全息虚拟动漫人物执行与交互请求匹配的交互动作(例如，害羞)，此时，用户可以观看到全息虚拟动漫人物执行该交互动作，从而完成用户与全息虚拟动漫人物之间的互动。
在本实施例中，全息投影设备采用了先通过触摸板获取触摸操作，以便对触摸操作进行识别，再根据识别出的触摸操作生成交互请求，以便根据交互请求执行与交互请求匹配的交互动作的控制方法，在该控制方法中，由于可以直接通过触摸板接收到的触摸操作对全息投影设备进行控制，从而丰富了对全息投影设备进行控制的指令，提高了与全息投影虚拟角色进行互动的灵活性。
可选地，上述交互动作可以但不限于为全息投影虚拟角色的肢体动作和/或全息投影虚拟角色的发声。例如，“控制全息投影虚拟角色执行与交互请求相匹配的交互动作”可以是控制全息投影虚拟角色播放与交互请求相匹配的动画；和/或，控制全息投影虚拟角色播放与交互请求相匹配的音频。
可选地，上述控制全息投影虚拟角色播放音频可以但不限于为控制全息投影虚拟角色的嘴部进行变化，同时使用声音播放装置播放音频。
可选地，上述触摸操作可以通过触点与触摸板相互作用所生成的触摸信息获取。在获取到上述触摸信息后，根据上述触摸信息识别出触摸操作。
可选地，上述触摸信息可以但不限于为以下至少之一：触点的触摸作用时长、触点的触摸轨迹、触点所在的触摸位置。
可选地，上述触点可以但不限于为人体或者人体使用的工具与触摸板之间的接触位置。上述人体可以但不限于为人的任何一个部位，例如，手指、手掌、手背、指甲、额头、下巴、脸颊或者其他部位等。可选地，上述触点可以但不限于为多个，例如，手掌与触摸板进行接触，则会形成多个触点。多个触点之间是同步的且动作一致。而若是手指与触摸屏接触，则会形成一个触点。上述触摸信息可以但不限于为触点的移动信息或者触点的时间信息。例如，以上述 触点为手指与触摸屏之间的接触位置为例进行说明。手指在与触摸板进行接触的过程中，可能会进行移动，从而在触摸屏上留下轨迹；或者手指单次接触触摸屏并短时间内离开从而对触摸屏进行点击操作。如此，可以将上述轨迹或者点击操作作为触摸信息，以便根据上述触摸信息识别触摸操作。
可选地，全息投影设备根据触摸信息识别触摸操作包括：
(1)在触摸信息指示触点在触摸板上所执行的划动动作的次数大于第一阈值的情况下，全息投影设备确定触摸操作为对全息投影虚拟角色执行抚摸操作，其中，触点在触摸板上移动的距离大于第二阈值的动作，将被识别为划动动作；
(2)在触摸信息指示触点在触摸板上移动的距离小于第三阈值，且触点在触摸板上的作用时长小于第四阈值的情况下，全息投影设备确定触摸操作为对全息投影虚拟角色执行拍打操作。
可选地，上述第一阈值、第二阈值、第三阈值、第四阈值可以但不限于根据经验值设定。以上述触点为手指与触摸板进行接触所形成为例，如图3所示，当手指与触摸板接触形成触点A后，手指进行移动，由触点A移动到触点B，移动距离为a。判断a与第一阈值的关系，如果a大于等于第二阈值，则表示本次操作为滑动操作。而如果a小于了第三阈值，则表示本次操作并不是滑动操作，还需要根据其他条件进行判断。可选地，上述作用时长可以但不限于为单次的触点存在时长。例如，手指与触摸板接触了1秒，则作用时长为1秒。
进一步地，在确定为本次操作为滑动操作的情况下，若接收到多次滑动操作，则对接收到的滑动操作的次数进行判断，如果滑动操作的次数大于了第一阈值，则全息投影设备可以计算得出用户对触摸板执行了多次滑动操作。此时，全息投影设备可以得到用户正在执行抚摸操作。而如果本次操作不为滑动操作，且本次操作的作用时长小于了第四阈值，则全息投影设备可以计算得出用户对触摸板执行了单次的短时触碰操作。此时，全息投影设备可以得到用户正在执行拍打动作。
可选地，全息投影设备确定触摸操作为对全息投影虚拟角色执行抚摸操作可以但不限于通过以下方法：全息投影设备获取第一时刻触点在触摸板上所停留的第一位置，及第二时刻触点在触摸板上所停留的第二位置，其中，第一时 刻到第二时刻之间的时间间隔为一个帧周期；并在第一位置到第二位置之间的距离大于第二阈值的情况下，全息投影设备将触点从第一位置移动到第二位置的动作识别为划动动作，并对划动动作的次数进行加一计数；而且，在划动动作的次数大于第一阈值的情况下，全息投影设备确定触摸操作为对全息投影虚拟角色执行抚摸操作。
可选地，可以但不限于对触摸屏添加坐标信息。例如如图4所示，图4为可选的触摸屏的触摸节点。以触摸屏的左下角为原点，触摸屏为平面设置平面直角坐标系。则触摸屏上的任意一点都可以获取到坐标值。例如C点的坐标为(x，y)，x，y均为正数。
可选地，结合图5对手掌与触摸屏进行接触的情况进行说明。在确定触摸板处于待检测状态(也就是S502)时，手掌与触摸板进行接触，通过S504判断触点的数量是否大于3，在触点大于3的情况下，通过S506记录触点坐标。此时可以选择其中一个触点的坐标或者将所有触点的坐标均记录下来。在触点消失时，通过S508判断触点消失前触点数量是否大于3，在是的情况下，通过S510记录触点消失的坐标。此时可以选择记录了开始坐标的触点并记录消失坐标，或者记录所有的触点的消失坐标。每一个触点的开始坐标与消失坐标相对应。通过S512计算一个触点的开始坐标与消失坐标之间的距离D，并通过S514判断D是否大于第二阈值。若是，则通过S516将滑动动作次数E加1。通过S518判断E是否大于第一阈值，若是，则判断出当前执行的动作为抚摸操作。在此过程中，若S504与S508中触点的数量不大于3，或者确定当前动作为抚摸操作之后，执行S522，将E重置为0。需要说明的是，上述判断触点数量是否大于3，其中的3是可以灵活进行设置的。同时，上述过程是判断手掌是否在执行抚摸操作的过程。若是判断手指(或者其他部位)是否在抚摸，则可以但不限于将图5中的过程中的S504、S508的步骤删除，不需要判断触点的数量是否大于3，使用图5中的剩余步骤即可确定当前操作是否为抚摸操作。
可选地，全息投影设备确定触摸操作为对全息投影虚拟角色执行拍打操作可以但不限于通过以下方法：全息投影设备获取第三时刻触点在触摸板上所停留的第三位置，及第四时刻触点在触摸板上所停留的第四位置；在第三位置到第四位置之间的距离小于第三阈值，且第三时刻到第四时刻之间的时间间隔小 于第四阈值的情况下，确定触摸操作为对全息投影虚拟角色执行拍打操作。
例如，以下结合图6进行说明。以触摸操作为手掌对触摸板的操作为例，在确定触摸板处于待检测状态(也就是S602)时，当手掌对触摸板进行触摸之后，通过S604检测到触点数量是否大于3，若是，则通过S606记录一个触点或者所有触点的坐标与产生时刻。通过S608判断触点数量是否等于0，若是，则记录上述一个触点或者所有触点的触点消失坐标与消失时刻，并通过S610计算触点坐标间距离L(也就是，一个触点的开始坐标与消失坐标之间的距离)与触点的产生时刻与消失时刻的时间间隔T。通过S612判断L是否小于第三阈值，并通过S614判断T是否小于第四阈值。在L小于第三阈值且T小于第四阈值的情况下，则可以通过S616确定当前操作为拍打操作。若L大于等于第三阈值或者T大于等于第四阈值或者在判断到当前动作为拍打操作后，都会重新处于S602待检测状态。且若是检测过程中触点未消失，则会周期性地记录触点的位置与当前时刻。
可选地，在全息投影设备根据触摸信息识别触摸操作之后，还包括：全息投影设备获取触点和触摸板进行相互作用的作用区域；全息投影设备根据作用区域在触摸板上的位置，确定交互请求所请求的互动信息。
例如，如图7所示，将触摸板分为A、B、C、D、E、F六个区域，在不同的区域产生的相互作用对应不同的互动信息。
可选地，上述将触摸板分成不同的区域后，上述区域大小、形状可以相同也可以不同，所分成的区域的块数可以为大于等于1的任何正数。
可选地，全息投影设备根据作用区域在触摸板上的位置，确定交互请求所请求的互动信息包括以下两个步骤中的至少一个：
(1)全息投影设备根据作用区域在触摸板上的位置，确定与全息投影虚拟角色进行互动的角色部位；并根据角色部位确定交互请求所请求的互动信息。
可选地，可以但不限于将触摸板分成不同的区域，不同的区域代表不同的角色部位。例如如图8所示，将触摸板分成6块，每一块分别与角色的头部、左臂、右臂、肚子、左腿、右腿对应。触摸不同的区域则表示与角色的不同的身体部位进行互动。例如，拍打头部、抚摸肚子等。
(2)全息投影设备根据作用区域在触摸板上的位置，确定与全息投影虚拟角色进行互动的互动类型；并根据互动类型确定交互请求所请求的互动信息。
可选地，上述互动类型可以但不限于包含互动形式或者互动模式。上述互动形式可以但不限于为角色所执行的动作或者播放的声音，上述互动模式可以但不限于包含当前角色所处于的模式。
可选地，上述模式可以但不限于为多种仿人类感情的模式。例如，害羞模式，生气模式，害怕模式，撒娇模式等等。
例如，图9为将触摸板的不同位置设置为执行不同的互动形式(例如，跳舞，唱歌等)；而且，图10为将触摸板的不同位置设置为不同仿人类感情的模式(例如，害羞模式、撒娇模式)。
可选地，该交互控制方法还包括：全息投影设备调整全息投影虚拟角色的情感参数；若确定情感参数在达到目标值，则全息投影设备控制所述全息投影虚拟角色的角色响应模式，和/或，全息投影设备开启全息投影虚拟角色在虚拟场景中的隐藏技能。
需要说明的是，本申请实施例不限定“全息投影设备调整全息投影虚拟角色的情感参数”执行时间，例如，其可以在控制全息投影虚拟角色执行与交互请求相匹配的交互动作时执行。
可选地，上述情感参数可以通过数字表示，或者通过红心的数量、能量值等形式表示。上述隐藏技能可以但不限于为新的动画、新的声音或者为新的阶段等。例如以上述隐藏技能为新的动画为例，在情感参数到达一定的值后，可以允许角色播放新的动画。而若情感参数未达到一定的值，则不允许角色播放新的动画。
通过本实施例，全息投影设备通过触摸板获取触摸操作，并对触摸操作进行识别，根据识别出的触摸操作生成交互请求，并根据交互请求执行与交互请求匹配的交互动作的方法，由于在上述方法中，可以直接通过触摸板接收到的触摸操作对全息投影设备进行控制，从而丰富了对全息投影设备进行控制的指令，提高了与全息投影虚拟角色进行互动的灵活性。
基于上述介绍的场景内容，下面将结合上述场景内容详细介绍本申请实施 例提供的交互控制方法的不同实施方式。
作为一种可选的实施方案，全息投影设备识别对全息投影设备上设置的触摸板所执行的触摸操作包括：
步骤1，全息投影设备获取与触摸操作对应的触点和触摸板相互作用所产生的触摸信息；
步骤2，全息投影设备根据触摸信息识别触摸操作。
以手指与触摸板进行互动为例，当手指与触摸板进行接触后，接触的位置为触点。如果手指进行移动，则触点也会随之移动。获取到触点的移动轨迹、手指的触摸作用时长、触点所在的位置作为触摸信息，根据触摸信息识别触摸操作。
通过本实施例，通过获取到触摸操作对应的触点与触摸板相互作用产生的触摸信息并根据触摸信息是被触摸操作，从而提高了全息投影设备的控制灵活性。
作为一种可选的实施方案，全息投影设备根据触摸信息识别触摸操作包括：
步骤1，当根据触摸信息确定触点在触摸板上所执行的划动动作的次数大于第一阈值时，全息投影设备确定触摸操作为对全息投影虚拟角色执行抚摸操作，其中，所述划动动作是指触点在触摸板上移动的距离大于第二阈值的动作；
步骤2，当根据触摸信息确定触点在触摸板上移动的距离小于第三阈值，且触点在触摸板上的作用时长小于第四阈值时，全息投影设备确定触摸操作为对全息投影虚拟角色执行拍打操作。
可选地，上述第一阈值、第二阈值、第三阈值、第四阈值可以但不限于根据经验值设定。以上述触点为手指与触摸板进行接触所形成为例，如图3所示，当手指与触摸板接触形成触点A后，手指进行移动，由触点A移动到触点B，移动距离为a。判断a与第一阈值的关系，如果a大于等于第二阈值，则表示本次操作为滑动操作。而如果a小于了第三阈值，则表示本次操作并不是滑动操作，还需要根据其他条件进行判断。可选地，上述作用时长可以但不限于为单次的触点存在时长。例如，手指与触摸板接触了1秒，则作用时长为1秒。
进一步地，在确定为本次操作为滑动操作的情况下，若接收到多次滑动操 作，则对接收到的滑动操作的次数进行判断，如果滑动操作的次数大于了第一阈值，则全息投影设备可以计算得出用户对触摸板执行了多次滑动操作。此时，全息投影设备可以得到用户正在执行抚摸操作。而如果本次操作不为滑动操作，且本次操作的作用时长小于了第四阈值，则全息投影设备可以计算得出用户对触摸板执行了单次的短时触碰操作。此时，全息投影设备可以得到用户正在执行拍打动作。
通过本实施例，通过将触摸信息与第一阈值、第二阈值以及第三阈值、第四阈值进行比对，从而确定出当前的触摸操作为抚摸操作还是拍打操作，从而提高了对当前触摸操作进行判断的准确性，进而提高了对全息投影设备的控制灵活性。
作为一种可选的实施方案，全息投影设备确定触摸操作为对全息投影虚拟角色执行抚摸操作包括：
步骤1，全息投影设备获取第一时刻触点在触摸板上所停留的第一位置，及在第二时刻触点在触摸板上所停留的第二位置，其中，第一时刻到第二时刻之间的时间间隔为一个帧周期；
步骤2，在确定第一位置到第二位置之间的距离大于第二阈值时，则全息投影设备将触点从第一位置移动到第二位置的动作识别为划动动作，并对划动动作的次数进行加一计数；
步骤3，在确定划动动作的次数大于第一阈值时，则全息投影设备确定触摸操作为对全息投影虚拟角色执行抚摸操作。
例如结合图5对手掌与触摸屏进行接触的情况进行说明。触摸板处于待检测状态(也就是S502)。此时，手掌与触摸板进行接触，通过S504判断触点的数量是否大于3，在触点大于3的情况下，通过S506记录触点坐标。此时可以选择其中一个触点的坐标或者将所有触点的坐标均记录下来。在触点消失时，通过S508判断触点消失前触点数量是否大于3，在是的情况下，通过S510记录触点消失的坐标。此时可以选择记录了开始坐标的触点并记录消失坐标，或者记录所有的触点的消失坐标。每一个触点的开始坐标与消失坐标相对应。通过S512计算一个触点的开始坐标与消失坐标之间的距离D，并通过S514判断D是否大于第二阈值。若是，则通过S516将滑动动作次数E加1。通过S518判断E是 否大于第一阈值，若是，则判断出当前执行的动作为抚摸操作。在此过程中，若S504与S508中触点的数量不大于3，或者确定当前动作为抚摸操作之后，执行S522，将E重置为0。需要说明的是，上述判断触点数量是否大于3，其中的3是可以灵活进行设置的。同时，上述过程是判断手掌是否在执行抚摸操作的过程。若是判断手指(或者其他部位)是否在抚摸，可以但不限于将图5中的过程中的S504、S508的步骤删除，不需要判断触点的数量是否大于3，使用图5中的剩余步骤即可确定当前操作是否为抚摸操作。
通过本实施例，通过上述方法确定当前操作是否为抚摸操作，从而提高了对当前触摸操作进行判断的准确性，进而提高了全息投影设备的控制灵活性。
作为一种可选的实施方案，全息投影设备确定触摸操作为对全息投影虚拟角色执行拍打操作包括：
步骤1，全息投影设备获取第三时刻触点在触摸板上所停留的第三位置，及第四时刻触点在触摸板上所停留的第四位置；
步骤2，在确定第三位置到第四位置之间的距离小于第三阈值，且第三时刻到第四时刻之间的时间间隔小于第四阈值时，全息投影设备确定触摸操作为对全息投影虚拟角色执行拍打操作。
例如，以下结合图6进行说明。以触摸操作为手掌对触摸板的操作为例，触摸板处于S602待检测状态。当手掌对触摸板进行触摸之后，通过S604检测到触点数量是否大于3，若是，则通过S606记录一个触点或者所有触点的坐标与产生时刻。通过S608判断触点数量是否等于0，若是，则记录上述一个触点或者所有触点的触点消失坐标与消失时刻。通过S610计算触点坐标间距离L与触点的产生时刻与消失时刻的时间间隔T。通过S612判断L是否小于第三阈值，通过S614判断T是否小于第四阈值。在L小于第三阈值且T小于第四阈值的情况下，则可以通过S616确定当前操作为拍打操作。若L大于等于第三阈值或者T大于等于第四阈值或者在判断到当前动作为拍打操作后，都会重新处于S602待检测状态。且若是检测过程中触点未消失，则会周期性地记录触点的位置与当前时刻。
通过本实施例，通过上述方法确定当前操作是否为拍打操作，从而提高了对当前触摸操作进行判断的准确性，进而提高了全息投影设备的控制灵活性。
作为一种可选的实施方案，全息投影设备获取第四时刻触点在触摸板上所停留的第四位置包括：
步骤1，在获取到触点在触摸板上所停留的第三位置之后，全息投影设备在每个帧周期中执行以下步骤，直至检测到触摸操作结束：
步骤2，全息投影设备获取在当前帧周期中的目标时刻触点在触摸板上所停留的当前位置，其中，第三时刻到目标时刻之间的时间间隔为N个帧周期，N≥1，且N为整数；
步骤3，在检测到触摸操作未结束的情况下，全息投影设备获取在当前帧周期之后的下一个帧周期中的目标时刻触点在触摸板上所停留的目标位置，将下一个帧周期中的目标时刻作为当前帧周期中的目标时刻，将下一个帧周期中触点所停留的目标位置作为当前位置；
步骤4，在检测到触摸操作结束的情况下，全息投影设备将当前帧周期中的目标时刻作为第四时刻，将当前位置作为第四位置；
步骤5，其中，触点在触摸板上的作用区域小于等于第五阈值的情况下，确定触摸操作结束。
例如继续以手指与触摸板接触的情况为例进行说明。当手指与触摸板接触时，获取到触点的当前位置与当前时间。若触摸操作未结束，则获取下一个帧周期的触点的触摸位置与触摸时间，一直到触摸操作结束时，获取到结束前一刻的触摸位置与触摸时间，将结束前一刻的触摸位置确定为第四位置，将结束前一刻的触摸时间确定为第四时间。由于手指与触摸板的触点面积随着手指压力的增大而增大，因此若触点面积减小到一个经验值内，则表示触摸操作已经结束，手指离开了触摸板。
通过本实施例，通过上述方法确定第四时刻与第四位置，从而提高了获取第四时刻与第四位置的准确性。进一步提高了全息投影设备的控制灵活性。
作为一种可选的实施方案，在根据触摸信息识别触摸操作之后，还包括：
步骤1，全息投影设备获取触点和触摸板进行相互作用的作用区域；
步骤2，全息投影设备根据作用区域在触摸板上的位置，确定交互请求所请求的互动信息。

可选地，上述将触摸板分成不同的区域后，上述区域大小、形状可以相同也可以不同，所分成的区域的块数可以为大于等于1的任何正数。
通过本实施例，通过根据触点和触摸板的相互作用的作用区域在触摸板上的位置确定互动信息，从而提高了全息投影设备的控制灵活性。
作为一种可选的实施方案，全息投影设备根据作用区域在触摸板上的位置，确定交互请求所请求的互动信息包括以下两个步骤中的至少一个：
(1)全息投影设备根据作用区域在触摸板上的位置，确定与全息投影虚拟角色进行互动的角色部位；根据角色部位确定交互请求所请求的互动信息；
(2)全息投影设备根据作用区域在触摸板上的位置，确定与全息投影虚拟角色进行互动的互动类型；根据互动类型确定交互请求所请求的互动信息。
可选地，上述互动类型可以但不限于包含互动形式或者互动模式。上述互动形式可以但不限于为角色所执行的动作或者播放的声音，上述互动模式可以但不限于包含当前角色所处于的模式。
可选地，上述模式可以但不限于为多种仿人类感情的模式。例如，害羞模式，生气模式，害怕模式，撒娇模式等等。
例如，如图8所示，将触摸板分成6块，每一块分别与角色的头部、左臂、右臂、肚子、左腿、右腿对应。触摸不同的区域则表示与角色的不同的身体部位进行互动。例如，拍打头部、抚摸肚子等。或者如图9、10所示。图9为将触摸板的不同位置设置为执行不同的互动形式(例如，跳舞，唱歌等)；而图10为将触摸板的不同位置设置为不同仿人类感情的模式(例如，害羞模式、撒娇模式)。
通过本实施例，通过根据作用区域在触摸板上的位置的不同确定全息投影虚拟角色的互动的角色部位或者互动类型，从而提高了全息投影设备的控制灵活性。
作为一种可选的实施方案，全息投影设备控制全息投影虚拟角色执行与交互请求相匹配的交互动作包括以下至少之一：
(1)全息投影设备控制全息投影虚拟角色播放与交互请求相匹配的动画；

通过本实施例，通过控制全息投影虚拟角色播放动画或者播放音频，从而提高了全息投影虚拟角色的灵活性。
作为一种可选的实施方案，所述交互控制方法还包括：
全息投影设备调整全息投影虚拟角色的情感参数；若确定情感参数在达到目标值时，则全息投影设备控制所述全息投影虚拟角色的角色响应模式，和/或，全息投影设备开启全息投影虚拟角色在虚拟场景中的隐藏技能。
可选地，上述情感参数可以通过数字表示，或者通过红心的数量、能量值等形式表示。上述隐藏技能可以但不限于为新的动画、新的声音或者为新的阶段等。例如以上述隐藏技能为新的动画为例，在情感参数到达一定的值后，可以允许角色播放新的动画。而若情感参数未达到一定的值，则不允许角色播放新的动画。
例如，以红心的数量表示情感参数。在经过与全息投影虚拟角色进行互动后，红心的数量到达一定的值，此时全息投影虚拟角色可以产生新的变化，例如，可以跳舞，或者唱歌，或者换衣服等。
通过本实施例，通过根据情感参数的多少进而决定是否开启全息投影虚拟角色的隐藏技能，从而提高了全息投影设备的控制灵活性。
需要说明的是，对于前述的各方法实施例，为了简单描述，故将其都表述为一系列的动作组合，但是本领域技术人员应该知悉，本申请并不受所描述的动作顺序的限制，因为依据本申请，某些步骤可以采用其他顺序或者同时进行。其次，本领域技术人员也应该知悉，说明书中所描述的实施例均属于优选实施例，所涉及的动作和模块并不一定是本申请所必须的。
