2.2. Data Collection and Analysis
- (1)
- Observation
- (2)
- Semi-structured interview
3. Results
3.1. User Research Results
- (1)
- Most teaching stops at the traditional two-feet basic jump
- (2)
- Physical health awareness is lacking
- (3)
- Gamification brings fun
- (4)
- Social support brings motivation
- (1)
- Parents need teaching guides
- (2)
- Recording is necessary
- (3)
- Parents’ worry about smart products
3.2. Persona
3.3. Product Positioning
- (1)
- The intelligent skip rope service system is composed of hardware products and software products. The hardware products are portable and easy to use. The interface of the software is intuitive and simple.
- (2)
- The hardware products of the intelligent skipping rope service system consists of a smartwatch and an intelligent skipping rope. They support multichannel data acquisition of exercise data and health condition.
- (3)
- The hardware products of the intelligent skipping rope service system also bring about interactions between terminals and between users, which improves the user experience and increase the frequency of use.
- (4)
- The software of the intelligent skipping rope service system could generate personalized exercise plans, provide skill guidance, integrate and analyze users’ daily exercise data, and provide multifaceted feedback to encourage users to skip rope for fitness and fun.
4. Hardware and Software Product Design
4.1. Hardware Product Design
4.1.1. Hardware Appearance Design
4.1.2. Modular Implementation
- (1)
- Skipping rope data acquisition module
- (2)
- Data reception and processing module
- (3)
- Cloud storage and analysis module
- (4)
- Display and interaction module
4.2. Software System Interface Design
4.2.1. First Round of the Interface Design
- (1)
- Functional implementation
- (2)
- Incentive feedback system
4.2.2. Software Interface Usability Testing and Results
- Task 1 and Task 3. The icon of My Garden was misleading: users mistook it as the Homepage. Additionally, the order of the tab arrangement did not correspond to the order of use, since the users assumed the first tab on the left was the interface to start with.
- Task 2. In the process of forming a plan, users couldn’t make changes to the content previously filled in.
- Task 4. Users expressed a need to record additional workouts after completing the daily scheduled exercise.
- Task 5. By simply displaying the heart rate value, users couldn’t determine for themselves whether their heart rate was within the normal range.
- Task 7. Users couldn’t quickly understand what the My Garden interface was for. They neither knew how to obtain the water to care for the plant nor what would happen if they kept watering the plant.
4.2.3. Optimized Interface
5. Discussion
5.1. User Requirements of General Importance
5.2. Implications for Design Research
5.3. Study Limitations and Future Directions
