A New Strategy !

Last quarter, we recruited students to contribute their fingerprint samples to our dataset; however, collecting everyone's pruney fingerprint was time consuming and inconvenient since they were required to hold their fingers in a cup of warm water for 20 minutes which did not let them do much while they were waiting. Although we expected to see a lot of pruning after exposing the subject's finger to water for 20 minute, the effect was minute. Thus in order to make the procedure more effective and less inconvenient, we came up with a new way of exposing fingers to water. Instead of having everyone immersing their fingers in warm water for 20-30 minutes, we will ask them to put on a surgical glove (latex or non-latex) that has a small amount of water inside it. Based on our observations, this procedure not only provides more wrinkly fingers in a shorter amount of time (15-20 minutes), but also allows the volunteers to continue their work as they are waiting. Therefore, this brilliant experimental proceduer will replace the old one as we continue our research.
