The impact of force on acquiring a high quality
fingerprint image has been systematically studied by researchers
using single print optical scanners. A previous study examined
force levels that ranged from 3N to 21N using a single print
optical sensor. A second experiment used force levels ranging
from 3N to 11N using a capacitive and optical single print sensor.
Additional work has been conducted that looked at smaller
increments of force also using an optical sensor. This paper
contributes to the body of knowledge by using an alternative
fingerprint sensor, an alternative force level and compares it to
the auto-capture method.
