Around 40 years ago, Italian Architect Gianni Pettena was invited to the United states and perform his career. In 1971, a series of foldable and wearable chairs were deisgned by him. The picture to the right is ten students of Petenna walking and exhibiting their chairs
The design actually happens in a context of political protest. A part of artistic movement.
" itâ€™s not the chair which acts as a support for the human being but the human being who acts as a support for the chair. " -Mercier & AssociĂŠs Therefore human body becomes the place that accomodates the chair and its function. Once the chair is worn, it also adds to user's ability to sit and take a rest anywhere comfortably.
What's more, the chair produced in that particular age has some symbolic meaning. On the one hand, it strongly refuses others' judgements and is independent from conventions. On the other hand, it's explicity showing its users' claim for rights or aspiration for revolution.
We'll probably also try and add funtional components to the body.
In other word, while providing a function, design can also becomes a manifestation of our stances.
Our vision mainly consists of two parts . Peripheral vision and central vision. Peripheral vision is a part of vision that occurs outside the very center of gaze.
As the filed of central vision is limited and could be easily influenced by light conditiongs. Peripheral vision can provide us plenty information, even to some extent, the identity about the objects before we could concentrate on it. We'll also have a context for the focused object with the substantial information that peripheral vision provides. Just like a picture needs its context to convey most of its meanings, its theme.
Different animals have different fields of view, depending on the placement of the eyes. Humans have an almost 180-degree forward-facing horizontal field of view, while some birds have a complete or nearly complete 360-degree field of view. In addition, the vertical range of the field of view in humans is typically around 180 degrees. Peripheral vision is weaker in humans, compared with other animals
It is not quite possible to maintain optimal peripheral vision at all times, but it is easy to enhance this function to make a meaningful difference in overall visual performance. There basically 2 ideas for enhancement of pheripheral vision
1 One is the use of appropriate, low plus lenses which will alter the distribution of light, increasing the stimulation of peripheral retina. Another excellent tool is binasal occlusion, which also stimulates peripheral awareness.
2 Another one is to extand the boarder of our vision, for example wear a binosal occulution.
