| summary |
This study was conducted to test the effectiveness of a virtual filter that digitally compensates for age-related changes in color perception. Many elderly people experience declining color perception. Medical studies have been conducted on how elderly peoples lenses affect their color perception. However, digital practical method for improving elderly peoples color perception need to be developed. Subway map is a good example of many elders daily experience. To adapt virtual filters to subway maps colors, standard short-wavelength colors, namely purple and green, were selected for variance independence (VI) because colors with short wavelengths of 400-600 nm on visible light are difficult for elderly people to perceive. Standard color VIs of subway lines and VI transferred to artificial lenses were measured with a spectrophotometer. CIE LAB and RGB; Color value on virtual filter (VD) was analyzed from VI. This virtual filter was developed based on artificial lenses using Dynamo. A visual programming algorithm was developed to adjust the color of a virtual filter through an interface. The results showed that virtual filters can be used to help elderly people detect short-wavelength colors. Therefore, virtual filters should be incorporated into lenses for use by the elderly. |
