AI Technical Summary

Technical Problem

Existing remote assistance solutions for mobile terminal devices are prone to out-of-order or lost touch data packets in weak network environments, resulting in operation lag and touch point misalignment. Furthermore, they rely on high-bandwidth internet connections and high-level authorization, making installation difficult and unable to achieve smooth swipe trajectory restoration.

Method used

A trajectory thinning processing method is introduced on the control end, which sends only key touch points and packages them through the IMS network signaling channel. On the controlled end, a jitter buffer queue and a relative timestamp synchronization mechanism are introduced. Combined with a curve interpolation algorithm, trajectory fitting and reconstruction are performed to ensure that the touch point sequence is executed in the trigger order and delay rhythm.

Benefits of technology

It reduces the amount of communication data, avoids network signaling channel blockage, improves the smoothness, stability and adaptability of remote touch control of mobile terminal devices, and solves the problems of operation logic errors and touch point offset in weak network environments.

Abstract

The invention provides a control method and system for remote touch of mobile terminal equipment, and the method is used for the control system for remote touch of the mobile terminal equipment: a control end responds to an external triggering touch event, obtains an original touch point sequence, and carries out the track thinning of the original touch point sequence to obtain a first touch point sequence; the first touch point sequence and the time increment of each touch point in the first touch point sequence are packaged and sent to a controlled end through an IMS network signaling channel; the controlled end stores the first touch point sequence into a jitter buffer queue and sorts the first touch point sequence to obtain a second touch point sequence; performing track fitting reconstruction on the second touch point sequence based on the time increment to obtain a target touch point sequence; and performing normalization processing on the target touch point sequence, mapping the coordinates into absolute coordinates of the local resolution of the controlled end, and executing the touch effect of the absolute coordinates according to the time increment. Through the method, the smoothness, the stability and the adaptability of remote touch control of the mobile terminal equipment are improved.
