iOS Interface Invocation
1. Turn on the gesture detection feature switch (in Xmagic.h)
- (void)setFeatureEnableDisable:(NSString *_Nonnull)featureName enable:(BOOL)enable;
Fill in featureName with HAND_DETECT (can be imported from TEDefine.h), and set enable to true.
2. Set data callback (in Xmagic.h)
- (void)registerSDKEventListener:(id<YTSDKEventListener> _Nullable)listener;- (void)onAIEvent:(id)event{NSDictionary *eventDict = (NSDictionary *)event;if (eventDict[@"ai_info"] != nil) {NSLog(@"ai_info %@",eventDict[@"ai_info"]);}}
eventDict[@"ai_info"] is the returned JSON structured string data.
Callback JSON Data Description
In the callback JSON data, the gesture-related data is in "hand_info", and the format is as follows:
"hand_info": { "gesture": "PAPER", "hand_point_2d": [180.71888732910156, 569.2958984375, ... , 353.8714294433594, 836.246826171875]}
The explanations of each field in hand_info are as follows:
Field | Explanation |
gesture | Gesture Type Name |
hand_point_2d | Captured gesture data information |
The following gestures are currently supported:
