Locate and analyze 3 things that are frustrating, confusing, or difficult for you to use.

A light switch is meant to turn lights on or off. When there is only one button, it can make the user unsure what outcome will result. Most light switches have actual switches, which are easy to operate but also communicate to the user that their action has done something - simply by flipping up or down the switch, it provides the user feedback without needing to rely on any other sources, which may have a delay, like in this case, where the lights won't immediately come on. Also, this light switch relies on the tiny dot-lights on the left side of the button to communicate whether the lights are on or off, since there is no actual switch. This is unfortunate because they are not noticeable, further contributing to the problem.

The biggest problem for this design is that the expected conceptual model does not align with the purpose of the item. When the conceptual model fails, it creates an unclear understanding of what the item is meant for. This item resembles a marker or pen of some sort however when you remove the cap, you see it is a spray of some kind. No where on the item does it communicate to the user that it is a hand sanitizer bottle except for the tiny words printed on the label. This is not sufficient because since the words are so small and followed by a block of text, they are easily ignored.

This design has a lot of potential, it is a great way to incorporate a table for eating, studying, whatever, all while being comfortable in a chair/single couch. However, one particular issue makes it frustrating to many of its users. 

When you are engaging in any of the activities it is meant for, you need to be able to control how close you are to this table; however, there is no way to adjust it. The table is too small, too far to the side, making the table (its most valuable component) impractical to use unless you lean forward at an angle. Being forced to use this chair in a fixed position removes the next most valuable component: the comfort of a couch. 

Make the table larger and allow for rotation - this way, the user has much more table space available to them (increasing functionality), and the rotation allows for the table to be as close or far away as the user would like (not compromising comfort). The rotation in the table would allow the user to stand up effortlessly despite the table being larger.
