使用凝视输入持续时间在Google Cardboard中选择UI文本 [英] Use Gaze Input duration to select UI text in Google Cardboard

问题描述

我用自己的UI文本按钮修改了Google Cardboard DemoScene.默认情况下，这些按钮响应Onclick()或点击事件以触发操作.当用户在对象上凝视2秒钟时，我想触发这些操作.

I have modified the Google Cardboard DemoScene with my own UI text buttons. By default, these buttons respond to Onclick() or tap events to trigger actions. I would like to trigger these actions when the user sets their gaze on the object for 2 seconds.

我怀疑我需要在GazeInputModule中添加某种条件语句，但是我不知道如何测量时间.谁能指出我正确的方向?这是正确的方法还是我应该尝试其他方法?这对我来说仍然是很新的，因此即使是基本技巧也非常有帮助！

I suspect I need to add some kind of conditional statement in the GazeInputModule but I can't figure out how to measure the time. Can anyone point me in the right direction? Is this the right approach or should I try something else? This is all still pretty new to me so even basic tips are very helpful!

推荐答案

在这里，我启用了按钮，以便在定时的注视下单击.就我而言，我创建了一个用于加载下一个场景的按钮.

Here's how I enabled a button click on a timed gaze. In my case I created a button to load the next scene.

我在Unity游戏中创建了一个场景，因此我并不是从修改Google Cardboard DemoScene开始的，但是原理是相似的.

I created a scene in my Unity game, so I didn't start off with modifying the Google Cardboard DemoScene, but the principles are similar.

1. 创建一个名为"LoadSceneButton.cs"的脚本(或任何合适的名称，如"TimedGazeButton.cs"，并将其附加到要启用定时注视的按钮上.请参见示例脚本在按钮上，添加事件触发器"组件并设置触发器-请参见屏幕快照定时注视按钮事件触发器

   On the button, add the "Event Trigger" component and set triggers - see screenshot Timed gaze button Event Triggers

   • Pointer Enter到按钮的LoadSceneButton.SetGazedAt，并选中复选框以传递TRUE值.这表明用户已开始凝视该对象.
   • Pointer Exit到按钮的LoadSceneButton.SetGazedAt，然后取消选中该框以传递FALSE值.这表明用户已停止注视该对象并将标线移动到其他位置.
   • Pointer Enter to the button's LoadSceneButton.SetGazedAt, and check the box to pass in the TRUE value. This indicates that user has started gazing at the object.
   • Pointer Exit to the button's LoadSceneButton.SetGazedAt, and uncheck the box to pass in the FALSE value. This indicates that user has stopped gazing at the object and has moved the reticle somewhere else.

   当用户的标线移入按钮时，"LoadSceneButton.cs"将开始计时凝视.注视时间达到特定持续时间后，将调用按钮的OnClick事件.如果用户在此时间之前将标线移开，计时器将重置.

   The "LoadSceneButton.cs" will start timing the gaze when user's reticle moves into the button. Once the gaze time has reached a particular duration, the button's OnClick event is invoked. If the user moves the reticle away before that time, the timer is reset.

   我使用的Unity版本是2016年11月10日发布的Google Daydream技术预览版v5.4.2f2-GVR12，带有Google GVR SDK 1.0.3.

   The version of Unity I used was Google Daydream Technical Preview v5.4.2f2-GVR12 dated 10th November 2016, with Google GVR SDK 1.0.3.
