Six essential functions when using apps on mobile phones
Recommendations for the Waze app:
1. Add setting item: Speed adjustment is a slider from 0 to 15km/h to compensate for slower speed compared to reality due to gps latency
2. Change the current speeding warning threshold setting menu to a slider with values from -20km/h to 20km/h so that users can choose the appropriate warning threshold for each need.
3. Add voice speed warning sound option
4. Add option to Repeat overspeed warning: (Off, 5 seconds, 10 seconds, 15 seconds, 30 seconds, 60 seconds…)
5. Increase the size of the speed indicator and speed limit to match mobifone navigation
6. Add advance warning option, with warning distance (400m, 300m, 200m, 100m, 50m) so that the app can warn users sooner, especially when signs change in speed
