Description

Visual upset time-recorder of induction type Technical Field The invention relates to the technical field of intelligent timers, in particular to an inductive visual turnover timer. Background The turnover timer is popular in application scenes such as kitchen cooking, study and office work, and the interactive logic is visual, namely, different countdown time durations are corresponding to different display surfaces facing upwards, and the turnover timer can start timing after being turned to the corresponding surfaces. Such products commonly employ six-axis attitude sensors (e.g., three-axis accelerometers, MEMS six-axis attitude sensors) to detect the spatial orientation of the rollover timer, thereby triggering the corresponding timing function. However, the prior art has a significant functional limitation in that the flip action is used only as a simple binary trigger. For example, the 5-minute interface is flipped to the top, the flip timer starts the 5-minute countdown, and if the 10-minute interface is switched halfway, the 10-minute countdown is restarted. In the actual use process, the situation that the time length needs to be increased by 2 minutes in the middle of the timing process or the posture of the turnover timer deflects due to accidental touch, so that the whole timing progress is reset and cleared. At this time, the user can only rely on the physical keys to gradually adjust parameters or reconfigure, and the interaction fluency is obviously restricted. The essence of this problem is that existing products do not adequately mine the information dimension of the flip action. The flipping operation actually comprises a plurality of parameter dimensions, including a flipping angle, an angular velocity, a turning direction, a gesture holding time period, etc. 180 degrees of complete turning and 30 degrees of partial tilting, rapid turning and slow turning, which have essential differences in operation intention, but the existing gesture recognition algorithm of the turning timer usually adopts a single threshold judgment mechanism to equalize all turning behaviors. The coarse granularity characteristic of the control logic ensures that the fine functions of time fine adjustment, operation withdrawal, state inquiry and the like cannot be realized through the turning gesture, and the intuitive advantage of turning interaction cannot be fully exerted only by means of key assistance. In addition, when the product integrates multifunctional modules such as an alarm clock and a timing module, the overturn response logic in different working modes lacks uniformity. The time counting process loss caused by the false overturn has no recovery mechanism, the user needs to memorize the differentiated operation rules in each mode, the learning cost is higher, and the fault-tolerant processing capacity of the system for misoperation is weaker. Disclosure of Invention The invention provides an induction type visual turnover timer, which aims to solve the technical problems that the control logic of the conventional turnover timer is single, the multi-mode operation is split, the error operation fault tolerance is poor and the functional richness of turnover interaction and the fluency of user experience are improved by establishing a hierarchical turnover identification mechanism, a turnover key cooperative control system and an intelligent state memory recovery module in the prior art.
