Apparatus and method for detection of movement behind wearer of wearable device and signal

A wearable device for providing an alert to a user wearing the device about an approach of an object, comprising:

• a monitor device configured to display a screen including a plurality of user input buttons arranged in a matrix using manually engageable images;
• a user input device including a player selection device, an input for said monitor device, and an alert device, the player selection device configured to generate and transmit a signal indicating a player touch operation associated with each of the user input buttons, the monitor device configured to collect temperature data and compare the temperature data with a database to establish a predefined temperature value, the player selection device configured to receive an input to cause a notification of the value above a set standard;
• a controller including a processor programmed to:
• receive the signal from the user input device indicating the temperature data by the user;
• initiate the monitor device;
• determine a number of counts being monitored, each counts including a temperature within a certain range of the predefined temperature value for a predefined event time period;
• determine a reference count total as a function of the number of counts monitored in the predefined event time period;
• conduct a round of comparison of the count total against a standard total to determine whether the alert need be sent to the user;
• and
• send, via the alert device, the alert to the user of the wearable device about the approach of the object to the user.
