Engineering Contradiction Analysis
1Volume of moving object
If a small screen is used in smart wearable devices to maintain compact size, then device portability is improved, but manual information input convenience deteriorates
Solution Approach 1:
The touch panel is segmented into multiple independent touch zones (first touch zone, second touch zone, third touch zone) that can be operated independently. This allows the small screen to function as multiple virtual buttons, improving input convenience without increasing device size.
Solution Approach 2:
The invention adds a temporal dimension to the 2D touch panel by implementing multi-touch and sequential touch recognition. The control method recognizes different operation sequences (single touch, double touch, long press) to provide diverse control functions within the same physical space, effectively expanding functionality without increasing screen area.
2Adaptability or versatility
If more touch control zones are added to improve input functionality, then input versatility is improved, but device complexity increases
Solution Approach 1:
The same touch panel hardware serves multiple functions by recognizing different touch patterns (single touch, double touch, long press, multi-point touch) on the same physical zones. This universal approach provides diverse input functionality without adding separate hardware components, thus avoiding increased device complexity.
Solution Approach 2:
The control system distinguishes different operations by detecting parameters such as touch duration, touch frequency, and number of simultaneous touch points. By varying these parameters rather than adding physical components, the system achieves high input versatility while maintaining simple hardware architecture.

AI summary
The present disclosure discloses a smart wearable device and an information input method thereof. The smart wearable device comprises a secondary touch panel located on at least one side, and a primary screen touch panel located on a front side; when the smart wearable device is in an input state, the secondary touch panel and the primary screen touch panel respectively receive touch instructions; a touch chip detects the primary screen touch panel and the secondary touch panel, obtains touch instructions, processes them and then outputs them; a microcontroller unit sets a first mapping relationship between an event of switching controls in each layer of an input method application and the touch instruction of the secondary touch panel, sets a second mapping relationship between an event of switching different layers, an input confirmation touch event, an input deletion touch event and the touch instruction of the primary screen touch panel, and implements information input based on the first mapping relationship, the second mapping relationship, and the touch instructions. With the secondary touch panel being in cooperation with the primary screen touch panel, the technical solution makes information input more convenient and quicker, and solves the problem about undesirable user experience upon information input on a small-sized smart wearable device.
