Light & Interactivity : Week 2 Observation Assignment

-
  • Observation Assignment: Early morning, exterior.
After seeing the video tutorial for the competition, I chose to add the 2 images below for my early morning exterior observation.  The subject of emotional perception became key and the early morning light exudes peacefulness. 

For the most part looking at direct light is unpleasant but sunrise (Rayleigh scattering) offers accessible direct light perhaps this is due to the diffuse sky radiation or the the 28 degree angle. The first image is middle of winter but the photo is taken in Florida, unlike NY the angle doesn't seem as noticeable across seasons .  The sun is coming out from the East, There is almost no Illuminance as the light is not hitting in directly with full intensity. On the first image the reflective surface of the water is partially created by the shadows cast from the clouds. There is a soft gradient that accentuates the "prism effect". The hues range from light blue rgb(174,198,207)  to violet(121, 64,24)but in between there is a vibrant highly saturated orange rgb(255, 95, 31)  overall the light is warm.


"One way to see the colors of sunlight is by the use of a prism. The velocity of light decreases slightly as it moves into the prism, causing it to bend slightly. This is called refraction. The degree of refraction varies with the energy level each wave.The lowest energy light waves refract the least, while the highest energy waves exhibit the greatest refraction. The end result is a dispersion of light into a rainbow of colors. Rainbows are partly the result of sunlight refraction through a rain drop, which acts like a prism."

Color Models:

There are a number of different components to color and light. You can talk about component colors, either additive or subtractive; you can talk about hue, saturation, and lightness, or value.

RGB is a color model with three dimensions – red, green, and blue

HSV is a cylindrical color model that remaps the RGB primary colors into dimensions that are easier for humans to understand.

HSL is another cylindrical color model that shares two dimensions with HSV, while replacing the value dimension with a lightness dimension.
  • Hue specifies the angle of the color on the RGB color circle, exactly like HSV.
  • Saturation controls the purity of the color, exactly like HSV.
  • Lightness controls the luminosity of the color.

What does VR do well, and what is it lacking? For the most part VR has been used as an entertainment form. While the sensorial experience beyond the headset is becoming important, there is still a long way to go. On one hand it can efficiently transport us to a different headspace in a few seconds. I think VR researches needs to think away from the Vision and touch meaning just the physical experience and think more of the psychological effects of "tele transporting" people's minds. Last year I saw the work of VR used as a training tool and thought it was and exciting detour from the traditional VR entertainment. After seeing the new research for people “phantom limb syndrome" I'm looking forward to the new development in using VR as a therapeutic or telemedicine tool. https://www.youtube.com/watch?v=_uArpsDXkvw   VR article 1 VR article 2 **Based off the famous “seeing is believing” idiom, the project involves stimulating an affected area while corresponding ...

What is the role of bias in creating technological tools? I think using technological tools is one of the easiest ways to access a larger demographic therefore it should be created by All TYPES of people. For the past 20 years we have become more and more dependent on the information we consumed and exchange in a tech environment. Bias is real and it wasn't until less than a decade ago that the conversation about bias and the impact on people life's started to become more of a central topic. Now more than ever we need to give tools to people that otherwise don't have a voice in development of said technologies. Also understanding that Bias cannot disappear from one day to another, it a long process and we need to keep the conversation and education going.

WEB1 : Static Website  WEB2 : Interactive  (Google, Facebook) WEB3  : NFT market, VR experiences article   Just As Web3 Is Propelling Art, So Art Is Powering Web3 We can’t just copy and paste traditional representation into the Web3 space. The timing of the NFT explosion was during COVID. S hifting from analogue to digital experiences. It was a f inancially necessity for the Art market. **gamification, discoverability, and a sense of responsibility to make these virtual environments alive and trustworthy for visitors. The communities build around NFTs is what is supporting the NFT market in a way it is the opposite of the what is the happening from human connections to digital world. The NFT market is a large consumer of electricity and it is a limited resource. If we focus all resources into this market, we would need to neglect other parts of society that needs electricity.
