4. 1. Recording vibration
using real materials
PROBLEM: COLLECTING VIBRATION IS TIME-
CONSUMING TASK
Tectile toolkit
Actual materials are
required
2. Searching from
Vibration Database
LMT haptic texture database
Currently, Small variations
5. DEVELOPMENT PROCESS OF
VIBROTACTILE APP
3. Obtaining Vibration
1. Development
of App Core Part
2. Design of
Texture
Collect
material
…go back to previous process
Obtaining vibration is Iterative process
It has large impact on whole development workload
