Product semantics is a field of thought based on the idea that a product's form should readily communicate the function of the product. Thus, a product with good product semantics would typically not require the user to read a manual to comprehend its intended use.
To observe the principles of product semantics, a chair should look like it is meant to be sit on, a fork should look like it is meant to pierce food and deliver it to the mouth, and a cup should look like something a person drinks from.
Product semantics has also been extended in some cases to include the application of personality attributes to products. For instance, the Volkswagon Beetle has been described as a 'happy product'.
