Haptic feedback activated by pressure

Hi - I am completely new to Arduino and looking for help to build a prototype in creating vibrations based on the pressure applied to the sensors. Can anyone please let me know if they can help and guide me thru this process? I am located in New York and happy to work with anyone available or interested in this project. Thank you! Elena

How big will the vibrations be?
Violin string? Phone vibra? Heavy truck driving over a kerb? Richter Scale?

How big will the pressure be?
Feather tickle? Finger push? Human derriere sitting? SCUBA tank pressure?

What are the sensors and actuators ?
