+- **Human Interface Guidelines**, **HIG**
+
+    A set of recommendations for designing and developing user interfaces for 
+    mobile, desktop, convergent applications and workspace widgets.
+
+- **User Interface**, **UI** 
+
+    Generally, the goal of user interface design is to produce a user interface 
+    which makes it easy, efficient, and enjoyable (user-friendly) to operate a 
+    machine in the way which produces the desired result. This generally means 
+    that the operator needs to provide minimal input to achieve the desired 
+    output, and also that the machine minimizes undesired outputs to the 
+    human.

+- **User Experience**, **UX**
+
+    UX refers to a person's emotions and attitudes about using a particular 
+    product, system or service. It includes the practical, experiential, 
+    affective, meaningful and valuable aspects of human–computer interaction 
+    and product ownership. Additionally, it includes a person’s perceptions of 
+    system aspects such as utility, ease of use and efficiency. User experience 
+    may be considered subjective in nature to the degree that it is about 
+    individual perception and thought with respect to the system. User 
+    experience is dynamic as it is constantly modified over time due to 
+    changing usage circumstances and changes to individual systems as well as 
+    the wider usage context in which they can be found. In the end, user 
+    experience is about how the user interacts with and experiences the 
+    product.
