Machine perception is a term that is used to identify the capability of a computer system to interpret data in a manner that is similar to the way humans use their senses to relate to the world around them. The basic method that the computers take in and respond to their environment is through the attached hardware. Until recently input was limited to a keyboard, a mouse, or external hard drives, but advances in technology, both in hardware and software, have allowed computers to take in sensory input in a way similar to humans.
Machine perception allows the computer to use this sensory input, as well as conventional computational means of gathering information to gather information with greater accuracy and to present it in a way that is more comfortable for the user. These include computer vision, machine hearing, and machine touch.
Machine Vision 
Computer vision is a field that includes methods for acquiring, processing, analyzing, and understanding images and, in general, high-dimensional data from the real world in order to produce numerical or symbolic information, e.g., in the forms of decisions. Computer vision has many applications already in use today such as facial recognition, geographical modeling, and even aesthetic judgment.
Machine Hearing 
Machine hearing is the ability of a computer or machine to take in and process sound data such as music or speech. This area has a wide range of application including music recording and compression, speech synthesis, and speech recognition. Many commonly used devices such as a smartphones, voice translators, and even cars make use of some form of machine hearing.
Machine Touch 
Machine touch is an area of machine perception where tactile input from a user or from the environment can be processed by a machine or computer. Applications for this could allow for more direct communication with mechanical devices. Common examples are touch pads on devices like phones and laptops that allow for a more comfortable interaction with the given device.
