Definitions: Visual Amenity & Visual Pollution

LBGWMP_27bBefore stating a proposed definition, it may better to summarize what has been done: 

1. People are different in their visual preference, but the majority like to enjoy the visible environment and are concerned with what they like to see.

2. People adapt to living within the visual environment. The adaptation could be within the scale of amenity or pollution. To find the people’ s adaptation scale we have to evoke their feelings either by comparison or concentration. By the comparison method people change their adaptation or evaluation for an object or scene attribute by introducing some other value. On the other hand, with the concentration method, people also change their adaptation or evaluation if they try to evaluate a specific thing within the scene in relation to the same scene attribute. The result of these methods may arise from emotional reaction, connotative meaning, or both of them depending on their personal way of thinking. However, by concentrating a lot the so-called scene layers come to mind. The comprehensive perception for these layers, reflecting upon the scene attribute, has been called the general impression. While the concentrated perception of one, two or more layer’s in relation to the scene attribute has been called the specific impression.

The study approved that the specific impression induces the subjects to change their general impression to a new visual appraisal.
The new appraisal might be positive or negative in the scale of amenity and pollution. The appraisals offer an excellent diagnoses for the scene layers in order to know the amenity or pollution resources.

3. The analytical impression may become a stage after deciding the specific scene layer. The analytical stage is mainly searching for the answer for why there is pollution, and the same question may possibly be asked for the amenity. However, in the design realm “why?” is a very big question which has unlimited answers.
Therefore, with out a certain criteria to base the answer on, it will be difficult to find an agreement or logical reply . So, it is much better to encourage people to appraise the visible environment through such criteria. The criteria should be clear, not conflict with any other and most importantly to be a two-way appraisal; the visual through the physical features and the physical through the visual features, in other words, visual and function are both involved in the appraisal process, which was approved by the visual setting criteria.

4. The descriptive impression, keeps the researchers and professional aware of the perception feeling of people, from the beginning to the end and after the design or upgrade of projects. Therefore criteria treatment should be in line with people’s perception psychology. For example, changing the location or formation of an object where the criteria was found by consensus will not satisfy people until the new location or design satisfies their scale of pleasant, meaningful, and so on.
On the other hand, the impression gives very useful classification for the feeling of people’s perception which is important for treatment goals. For example, as we have read in the result and discussion chapter that residents, visitors and students have a common agreement for the visible environment description which is totally different from that of the professional workers, we should ask ourselves what the logical responsibility is for such a case.
In my opinion, if we follow the majority the visible environment will absolutely become much better physically as well as visually. But, if we follow only the professional workers of this study, then the physical situation may change but the visual situation will not improve and in fact may become worse.

5. Based on the above, the proposed definition of visual amenity and visual pollution is as follows:
Visual amenity and visual pollution are collective and subjective observations, and they can be defined by the level of common satisfaction. This satisfaction depends on the entirety of the criteria of the scene components . These criteria are associated with the mental process concerned with the organized meaning of location, formation, condition and relationship.
