Persistence of vision - Previs - Persistence of Vision



Persistence of vision is an optical illusion, it works on a simple phenomenon how our day to day television works. MY first pov was six months before with arduino uno and with motor. However it is best to have a small and portable device that can be carried anywhere and image can be seen without any external motors or fan.

This small portable pov version uses attiny 85 ic, smaller variant of arduino uno that uses atmega 328 ic. This time, I made pov to give my sister as a gift .There are many tutorials on how to make pov but lot of them have tons of wires and motors and many a time uses the arduino uno board itself .so I thought, to come with no wire small pov with built in power source and a switch. By switching the internal crystal speed to 1 MHZ of attiny85, the image was seen more clearly without any motor. With proper camera shutter speed control the image can be seen nice and clear.

I made a shield to do this connection ,also added the atmega 328 support to the shield the shield is put straight on the arduino uno and you can do program without any wires and breadboard.

The making of pov was less than 4$ this is very cheap gift you can give to any loved one.small and can be taken anywhere.

Captain Kathryn Janeway of the USS Voyager is on her way to engineering when Lieutenant Tom Paris calls her via combadge to inform her that he has finished plotting a course through Botha space. As Janeway continues toward engineering , Neelix approaches her and warns her that they will have to be careful as they travel through Bothan space. Janeway is short-tempered with Neelix and delays their discussion for later.

In the holodeck, Janeway runs Janeway Lambda one , a Gothic holographic novel (holonovel). The holonovel diverges from its original plot as Lord Burleigh , her employer in the holonovel, declares his love for her character and kisses her.

Their embrace is interrupted by the entrance of the housekeeper, Mrs. Templeton , and Lord Burleigh's children, Henry and Beatrice , for afternoon tea. The plot of the holonovel returns to its Gothic storyline as Janeway's character alludes to mysterious piano music coming from the music room and confronts Lord Burleigh about the mysterious goings-on in the house, including a fourth floor corridor she is forbidden to explore. The confrontation is interrupted when Janeway is called to the bridge by Chakotay to communicate with a representative of the Bothan government whose ship has approached Voyager .

When Janeway arrives on the bridge, Neelix warns Janeway that he has heard reports of numerous ships disappearing without explanation in Bothan space. He also warns her that the Bothans fiercely protect their territory from outsiders. The Bothan representative appears on the viewscreen obscured by strong lighting and orders Janeway to wait for a Bothan ship to rendezvous with Voyager before the Bothans decide if Voyager will be allowed to proceed through Bothan space.

Janeway proceeds to the mess hall with Neelix to continue their discussion and to eat lunch. On the buffet, she sees a plate of cucumber sandwiches eerily similar to the ones on the tea table in Lord Burleigh's mansion in her holonovel. As soon as she has recovered from the shock of the coincidence, Neelix serves her tea in a porcelain cup that appears to resemble exactly the porcelain cup that Beatrice, Lord Burleigh's daughter, broke in the holonovel program.

Janeway has convinced herself that these occurrences are coincidences, but as she walks down the corridor , passing by Lieutenant Ayala , she hears Lord Burleigh's voice reiterating his love for her. When she turns around, though, it's obvious Ayala wasn't speaking. Then she sees the image of Beatrice Burleigh in the corridor, and Beatrice speaks to Janeway and then vanishes.

Persistence of vision refers to the optical illusion that occurs when visual perception of an object does not cease for some time after the rays of light proceeding from it have ceased to enter the eye. [2] The illusion has also been described as "retinal persistence", [3] "persistence of impressions" [4] , simply "persistence" and other variations.

This has been believed to be the explanation for motion perception in cinema and animated films, but this theory has long been discarded by scientists.

It is assumed that the illusion that film historians often refer to as "persistence of vision" is the same as what is known as positive afterimages by psychologists. [5] The cause of positive afterimages is not well known, but possibly reflects persisting activity in the brain when the retinal photoreceptor cells continue to send neural impulses to the occipital lobe .

Early descriptions of the illusion often attributed the effect purely to imperfections of the eye, particularly of the retina . Nerves and parts of the brain later became part of explanations.

The fact that a glowing coal appears as a line of light when it is moved around quickly has been used to illustrate the idea of persistence of vision. [2] It is known as the "sparkler's trail effect", named after the trail that appears when a sparkler is moved around quickly.

The effect has been applied in the arts by writing or drawing with a light source recorded by a camera with a long exposure time.
