10 Usability Heuristics Applied to Video Games

Subway Surfers, an endless-runner mobile game, does a nice job crafting error messages. After users lose mid-game, they’re prompted with a dialog that reads, Save me! (Which would not be a good dialog prompt in a productivity app, but is acceptable in the playful context of a game.)

3 Design Considerations for Effective Mobile-App Permission Requests

What Are Permission Requests and Why Have Them? An app must request permission before accessing resources such as the camera, current location, or microphone, on the user’s mobile device.
