The invention relates to a mobile multi-element haptic fusion feedback device, comprises a plurality of multi-element tactile fusion feedback units, a rotating wheel and a moving platform, wherein themulti-element tactile fusion feedback unit comprises a feedback unit body and a feedback film arranged on an upper surface of the feedback unit body, and the multi-element tactile fusion feedback unit can provide stiffness feedback, temperature feedback and texture feedback; A plurality of multi-element haptic fusion feedback units are mounted on a rotating wheel, The rotating wheel is arranged on a multi-degree-of-freedom moving platform, the rotating wheel can rotate around the rotating shaft, and the moving platform drives the rotating wheel to move according to the position of the finger,so that the multi-tactile fusion feedback unit is aligned with the finger at the position of the finger, the position feedback is provided for the finger, and the continuous position feedback forms the shape feedback of the object. The device provides multi-tactile fusion feedback of stiffness feedback, temperature feedback, texture feedback, position feedback and shape feedback, so that users can have a rich experience of multi-tactile fusion feedback.

In some examples, techniques are provided for rapid tactile feedback that is local to individual non-actuated keys (eg, thin keyboards or keypads) without the use of a controller. Haptic feedback may be in the form of simulated "key click" feedback for an individual key pressed by the user, so that the finger used to press the key feels a tactile sensation. Haptic feedback mimics the tactile feel of mechanical keys (eg, buckling springs, pop-up dome key switches) to give the user the perception that they have actuated a mechanically movable key.

The present invention provides a pedestrian recognition method and system for adaptive depth spatial features; the method includes the steps of: segmenting the pedestrian image according to the preset segmentation number n; establishing n groups of feature extraction models with the same number of blocks as the pedestrian image, And correspondingly extract feature information from n blocks of pedestrian image blocks; establish n groups of feature classifiers with the same number of feature information groups, and correspondingly classify n groups of feature information; calculate each The loss value generated in the group feature classification process; return n groups of loss values ​​to the corresponding feature extraction model and feature classifier to optimize the feature extraction model and feature classifier. The present invention can effectively extract more information of pedestrians, especially local information, and adopts the adaptive pedestrian feature classification in the form of loss value feedback, and finally tends to the optimal solution, which can guide the pedestrian feature extraction model to extract more depth spaces pedestrian feature information.
