London design studio Special Projects has created a series of paper envelopes that seal away smartphones and minimise screen time for the day, while still allowing access to basic functionality.
Users can download and print two different envelopes ? one featuring a dial pad to make and receive calls and the other a simplified camera with no viewfinder, just buttons to capture photos and videos.
These work in coordination with an app, which takes over the entire screen and blocks all other functions or applications while it is being used.

"It's been a really interesting exercise taking a device with so many functions, masking it to remove all of them, and then slowly adding them back in," said Special Projects co-founder Adrian Westaway. "With the camera, we wanted to present the most extreme and clear version of the concept so we got rid of the screen altogether."
This creates a user experience similar to that of an analog 35 millimetre camera, complete with the anticipation to see how your photos turned out at the end of the day.

The project was inspired by stories of people going to extreme measures ? physically locking away their smartphones or buying old school Nokias ? in an attempt cut down their screen time.
Rather than expecting people to abstain completely, Envelope eases the process by allowing users to access only the functionality they actually need via a calm, minimalist design.
Paper maintains the touchscreen functionality, and is fragile...
