Affective computing is a growing research area used to develop the system in such a way to recognize, interpret, process and simulate the human emotions in a systematic manner. The main application of Affective computing is the human computer interaction, in which the communication between the human and the machine enhances by giving an appropriate response to the user in an effective and empathic manner. This paper mainly concentrates on the systems which can extract the previous, past and present information based on sequential circuit. Design sequential circuit (SC) with the help of reversible gate (RG) because RG is an emerging technology and consume low power and area. The SC is implemented Xilinx software and calculates parameters.
