Humans are usually said to have five senses: sight, hearing, taste, smell and touch. In fact these are just those from exteroception, that is gathering information about the outside world. There are also various forms of interoception, that is sensing internal things, including feeling a stomache ache and proprioception, the sense of where your limbs are relative to your body. For artificial senses, AI has focused most strongly on computer vision and hearing, especially speach recognition, but in robotics there is work on touch and also additional forms of sensing such as the use of sonar or infrared.
