Specifying apparatus and specifying method

A specifying apparatus comprising:

• a memory;
• and
• a processor coupled to the memory and configured to:
• specify a first period for which it is determined that a specific movement or a specific posture is being performed by applying a first threshold to time series data obtained from a sensor for detecting a movement of a person,
• specify a second period for which it is determined that the specific movement or the specific posture is being performed by applying a second threshold to the time series data, the second threshold being eased compared to the first threshold,
• specify a transitional period based on a difference between the second period and the first period, the transitional period corresponding to one of a period of a transition to the specific movement or the specific posture, and another period of another transition from the specific movement or the specific posture to another movement or another posture, and
• output a result of the specification of the transition period.

A specifying method for specifying a transitional period when transition to a specific movement or a specific posture is performed by a person or when transition is performed from the specific movement or the specific posture to another movement or another posture by the person, the specifying method comprising:

• acquiring time series data including a value, from a sensor for detecting the value in accordance with various movements of a person;
• specifying a first period for which a degree of similarity to a model representing the specific movement or the specific posture is equal to or greater than a first threshold, from the time series data;
• specifying a second period for which the degree of similarity to the model is equal to or greater than a second threshold which is smaller than the first threshold, from the time series data;
• specifying, by a processor, the transitional period based on a difference between the second period and the first period;
• and
• outputting information regarding the transitional period.
