Determination of customer proximity to a register through use of sound and methods thereof
View Patent ↗A method is disclosed for determining a customer's proximity to a checkout register at a store. A mobile electronic device with mobile self-checkout software thereon may record and analyze ambient noise to determine when a customer is in a checkout line as well as to track the customer's progress through the checkout line. The mobile self-checkout software may present information to the customer according to the customer's position in the checkout line. The type and nature of the information presented to the customer may be changed according to the customer's distance from the checkout terminal as well as how quickly the customer is approaching the terminal. The software may provide detailed data about the shopping and checkout experience. This information may be correlated to customer satisfaction and used identify particular strengths and weaknesses in the shopping experience offered by a store.
1. A method for determining a customer's location in a retail store checkout line comprising:
activating a mobile self-checkout software on a mobile electronic device;
the mobile electronic device sampling ambient noise;
the mobile electronic device analyzing said ambient noise to determine if the mobile electronic device is within a threshold distance of a POS terminal;
the mobile electronic device analyzing said ambient noise to determine if a beep sound from a POS terminal bar code scanner is present; and;
the mobile electronic device analyzing the rate of repetition of the beep sound to determine if the POS terminal is a self-checkout terminal or a conventional POS terminal.
2. A method for determining a customer's location in a retail store checkout line comprising:
activating mobile self-checkout software on a mobile electronic device;
the mobile electronic device sampling ambient noise; and
the mobile electronic device analyzing said ambient noise to determine if the mobile electronic device is within a threshold distance of a POS terminal; and
a returns POS terminal producing a predetermined noise when the customer is present at the returns POS terminal and the mobile electronic device analyzing said ambient noise to determine if said predetermined noise is present;
wherein said predetermined noise is not produced by a POS terminal during normal operations.
3. A method for determining a customer's location in a retail store checkout line using a mobile device comprising:
a mobile electronic device recording ambient noise;
analyzing with the mobile device the ambient noise to detect sounds from a POS terminal;
analyzing with the mobile device the sounds from the POS terminal to determine the proximity of the customer to the POS terminal;
the returns POS terminal producing a unique noise not produced during normal operation and
the mobile electronic device analyzing the ambient noise to determine whether said unique noise is present to determine if the mobile electronic device is within a threshold distance of a POS terminal.
4. A method for determining a customer's location in a retail store checkout line using a mobile device, comprising:
the mobile electronic device recording ambient noise;
the mobile electronic device analyzing the ambient noise to detect sounds from a POS terminal;
the mobile device analyzing the sounds from the POS terminal to determine the proximity of the customer to the POS terminal;
the mobile device analyzing the ambient noise to detect scanning beeps from a POS terminal; and
the mobile device analyzing the rate of repetition of said beeps to determine if the customer is within a threshold distance of a self-service POS terminal or a conventional POS terminal.
