I think that functional availability is the stimulation of the function of an object by human psychological presupposition, rather than just using the restricted function of the object itself to serve people, which will lack functional creativity. Just like in this video, the original object is a bucket. If you look at the properties of the bucket itself, its function is to contain liquid. Then if the liquid does not exist, according to the stereotyped thinking, this bucket is useless; then if according to the user’s psychological presupposition, that is, according to the needs of the bucket, it can be used as a stool for sitting, You can also stand on it as a roller, or lift it up as a sports equipment. In this way, the functions of this bucket will increase due to the user’s discovery, and the existence of the bucket will become more meaningful. Relatively, the frequency of use of the bucket will also become higher.
From the point of view of function in interaction design, the development and addition of functions should also be based on the needs and presets of the users themselves. Just as in the early days, mobile phones only had a call function, but with the increasing demands of users, mobile phones now integrate various communication and entertainment functions. Not only take photos and videos, you can also watch videos and play games. With the continuous advancement of society and technology, I believe that electronic devices with interactive functions will have more and more comprehensive functions in the future, making the interaction between people and devices more normal. This is the result of functional availability.
