Electrical device for hand gestures detection

A hand gesture detection electrical device for detecting hand gestures, comprising:

• an integrated circuit (IC) electronically integrating the following:
• a first interface configured to connect at least one imaging device;
• a second interface configured to connect to a controlled unit;
• a data storage configured to store a plurality of sequential logic models each representing one of a plurality of hand gestures, each of said sequential logic models comprises a pre-defined ordered sequence of at least one of a plurality of pre-defined hand poses and pre-defined hand motions, wherein each of said plurality of pre-defined hand poses and each of said plurality of pre-defined hand motions is represented by one of a plurality of pre-defined hand features records;
• a memory storing a code;
• and
• at least one processor configured to be coupled to said first interface, said second interface, said data storage and said memory, the at least one processor is configured to execute said stored code, said code comprising:
• code instructions to receive at least one of a plurality of timed images depicting a moving hand of a user;
• code instructions to generate a runtime sequence of at least one of a plurality of runtime hand datasets, said runtime sequence representing said moving hand;
• code instructions to match each of said at least one of said plurality of runtime hand datasets with a respective one of said plurality of pre-defined hand features records in a respective position in a sequence of each of said plurality of sequential logic models;
• code instructions to estimate which one of said plurality of hand gestures best matches said runtime sequence;
• and
• code instructions to initiate at least one action to said controlled unit, said at least one action is associated with a selected at least one of said plurality of hand gestures, said selection is based on said estimation;
• wherein each of said plurality of pre-defined hand poses depicts a static posture of a reference hand and wherein each of said plurality of pre-defined hand motions depicts a movement of said reference hand.
