A tactile source is a type of evidence or information that can be physically touched or felt, relating directly to the sense of touch

. In historical or educational contexts, tactile sources are objects or materials from the past that you can physically handle, such as artifacts, tools, coins, or any tangible item that provides information through direct contact

. In a broader sense, "tactile" means anything related to the sense of touch

. Tactile information is data obtained through physical interaction, such as pressure, texture, or shape, and is processed by the brain to help us understand and interact with our environment

. In technology and science, tactile sources can also refer to devices or sensors that detect and measure touch, pressure, or force, translating physical interactions into data or feedback

. For example, a fingerprint scanner is a tactile sensor that captures the unique pattern of a finger through touch

. In summary, a tactile source is any object, device, or material that provides information through physical touch, either as historical evidence, sensory input, or technological measurement
