Touch input from a user other than the primary device user causes unwanted input. Describe the existing solutions and their drawbacks. The primary user must prevent the screen from being touched by anyone that could potentially give unwanted input to the device. This can be difficult with kids, pets, co-workers, etc who touch the device screen.

Method to enter device distress mode
This idea identifies a user as the primary user of a device using one or more of the following:
- Camera: Identify the object touching the screen is part of the primary user's body using skeletal recognition. If a camera sees more than 2 hands or 10 fingers, it will triangulate the correct hands/fingers for the primary user
- Proximity sensor around perimeter of screen
- Angle of finger touching the screen (since typical finger touch from primary user would not occur from some angles)
Once a primary user is identified, only touch input from the primary user is accepted. Touch input from an unidentified source can be configured to accept or reject. Touch input from a user confirmed as not being the primary user is ignored.
The primary user may be automatically reset each time the device changes hands. For example, if the user hands the device to someone else the new primary user would be the only person in front of the screen. A time component may exist so that if the primary user sets the device down temporarily, the original primary user remains in effect for a certain time period.
A configurable gesture may exist to change the primary user or be required to allow input from a new user.
