Tag "day"

The daily cycles of day and night influence the experience in a number of ways. The main visual information is, beside the amount of light, the quality of the light. There are very different temperatures from morning to midday to evening.

Generally from the light quality the time of day can be guessed quite accurately. These shades are of course heavily influenced by weather and time of year. This can lead to a confusion with heavy dark clouds pulling up in the afternoon and it can give a sense that time has jumped and it might at two o’clock like it is half five. On the other hand if spent a few hours indoors, in a dark corner of your house, and as you step out into the sunlight the quality of light can be confusing in terms of time of day.

The light is identified by scientists as an important factor to set the body clock or circadian rhythm. This has been tested in experiments where participants spent weeks in caves with no daylight. The human body is able to maintain the cycles without the daylight reference for a long period. It does not depend on it as essential, but it provides a guidance to keep on track.

With this background, the architect Philippe Rahm has proposed a café that mimics the light quality of different times of the day. In essence Split Times Cafe proposes a 24 hour coffee place where you can have day or night at any time of day. The different areas recreate daytime light and night time light quality.

It is possible to dring the morning coffee in the night light condition area and have a beer in the bright daylight zone. The day light zone is showing the characteristic yellow light indicating bright sunshine. The night zone on the other hand is fulled with blue tone light referencing the blue dark moon light. The cafe also offers a third place that is proposed in clear glass and therefore being filled with the actual quality of the light at that very moment.

The light quality is achieved through the use of coloured glass. Yellow glass for the day and blue glass for the night. To support the atmosphere the furniture is distinct in the are the architects make use of the furniture. The day zone is organised horizontally where as the night zone’s furniture is oriented vertically.

More and more location data becomes available and makes it possible to visualise the beat of the city over longer periods and/or compressed as a speed up sequence.

Eric Fischer has recently published online a few mappings of online available location data. Most popular were the flickr maps of world cities. This time it is bus movement data through which he visualises San Francisco. The data was collected of the period of one month.

Visualisation of public transport vehicles in Vienna, Austria put together by Max Kossa on wissenbelasted.com . It is built from a database containing 1048 stops along 44 bus lines, 18 night bus lines and 29 tram lines. Within 24 hours there are some 510.026 total stops for all vehicles.

The different vehicle types are coded in colour. Green are the night buses. This is quite obvious at 01:30. At this time the regular service shuts down and the blue (tram) and red (bus) dots vanish for the rest of the night.

The author has published the scraped data base file for download if you want to have a play.

TimeLapse really makes sense to shorten a timespan and squeeze a lot of time into a short while. Well, everyone tried to do it all the time and multitasking is on e way of archiving something similar.
TimeLapse photography has something relaxing, partly because one can enjoy a few moments knowing you get only ‘the best of’. With this example you get the best of a popular holiday destination over one day in just 03:25, if this is no selling point.

An attempt to mimic the daylight in the city. The project is realised as an A-level art project by the student jamatkins. The sound scape is also quite nice, so turn your headphones up.

A visualization of world wide air traffic over a 24 hour period.
Amazing, how all these yellow dots swirl over the world map. The expected hotspots, the states and Europe as destinations show up. Although one would expect that we live in a 24 hour society especially regarding air traffic, the day night rhythm directs the number of flights. Flight activities pick up in the early morning hours ad dies out in the late night hours.
At the beginning one can observe how the flight traffic in the states slowly calms down and at the same time with the rise of the morning in Europe the number of flights picks up, enjoy!

The animation was produced to be shown on the high definition 3D-Globe “Orbitarium” in Technorama – The Swiss Science Center in collaboration with Institute of Applied Information Technology InIT, Zurich University of Applied Sciences, Winterthur. The data used is from 2008.
There is plenty of versions of this animation another one on vimeo.
