"PRISMO" is a tool that utilizes the front camera (in-camera) of smartphones. Invented by Jeffrey Daiker, who lives in Colorado, USA. It utilizes the property of prisms to change the direction of light travel.
To use "PRISMO", place the prism part on the front camera and wrap a silicon band around the smartphone to attach it. This makes it possible to turn the front camera 90 degrees.
When taking pictures of babies and pets with a smartphone camera, the photographer had to lie down on the floor to see the screen. If you install "PRISMO", you can put your smartphone on the floor and release the shutter while checking the state of your baby or pet on the screen.
Daiker says that the range of use of smartphone cameras can be expanded infinitely by simply installing "PRISMO". For example, a live house where you are allowed to take photos and videos. When shooting a performance with a smartphone, you must continue to support the smartphone with both hands. But with PRISMO, you can leave your smartphone on the table after tapping the shoot button. Users can relax and enjoy alcohol, food and music.
When used at work, it is also useful for recording important presentations. Some presenters of the presentation are reluctant to be pointed at the camera. However, if you use "PRISMO", you can easily shoot because you can only see the smartphone on your desk.
Daiker is running a campaign to recruit investors on the crowdfunding site kickstarter for the commercialization of "PRISMO". You can get one "PRISMO" with a $ 25 investment. The retail price after the campaign is $ 35. The shipping time is scheduled for December 2016.
If you can't wait until the end of the year, you may make your own. If you buy a silicone band and a prism and glue them together with super glue, you should be able to get something pretty close.
