My example of an object that is designed well is my new computer mouse. It certainly isn’t revolutionary, but compared to the $5 (new) mouse I’ve been using for the past few years it’s great.
The mapping relationships of any remotely decent mouse are very natural. The cursor on screen moves in the direction you move the mouse. A page scrolls in the direction you move the mouse wheel. Modern mice (?) allow for on the fly adjustable DPI, so if you are confined to a small space or like moving your arm a lot you can adjust the sensitivity of the cursor. The trackball has been dropped in favor of a sensor on the bottom which detects how much you are moving the mouse, making it smoother.
The mouse embodies a few of the characteristics of Enargeia. It conveys significance through it’s depiction – that is, the lighting. It gives pleasure to the viewer. If someone had never used a computer before they would instinctively know that it is a significant object for operation. Depending on your threshold it could evoke a sense of wonder, and if a person from 100 years ago saw it it would undoubtedly be unlike anything they’d seen before.
A computer mouse is an everyday object that we often take for granted because of how well the technology works. When you really look into how it operates it’s actually pretty interesting.
