A mezuzah is a case containing parchment with the Hebrew Shema prayer written inside. There is a commandment in the Torah that states you should “write the words of God on the gates and doorposts of your house.” This has manifested in the practice of hanging the mezuzah containing this prayer on the upper third of the right side of your doors. I was taught that you are supposed to touch the mezuzah and to kiss your hand afterwards when you walk through the door. When I thought about mezuzahs, the kissing felt like the main demonstration of devotion. After making this speculative design, I was surprised to find out that the touching and kissing is not based in scripture and is a relatively newer development (16th century.) Learning this changed my interpretation of my invention. The mitzvah (good deed, fulfilling a commandment from the Torah)

This Mezuzah has a break beam sensor that triggers a hamsa to press against the body of the mezuzah when someone walks through the doorway. My interpretation of this invention changed since I learned that the kissing/touching isn’t requested by G-d himself. Because the kissing is an acknowledgement of the fulfillment of another mitzvah, the automatic kisser feels like a nice way to automate the user’s acknowledgement while eliminating the high contact of people touching the same object and then touching their mouth.
