Interface research: Would touch screens work well in our eruption alert device?

 Pros of touchscreens for a digital pendant:

  1. It's easier to clean a screen than buttons.
  2. Has a luxurious appeal. That appeal might apply to social life, making them easier to sell to groups.
  3. If you can't fit every feature in at once, touchscreens offer an intuitive way to switch the viewport between them.
  4. If buttons stop working, touchscreens are a good backup.
  5. Touchscreens tend to be brighter and clearer by default than other screens. Important information can be seen better at a glance.

Cons of touchscreens for a digital pendant:

  1. Screens are badly effected by dirt, making them harder to use and see, especially in daylight.
  2. The visually impaired can't intuitively use touch screens the same way they can use physical buttons.
  3. They take more power than either buttons or basic screens.
    • Battery charge monitors aren't as accurate as they say, they might run out when the power says 20% for example.
  4. More expensive then basic buttons.
  5. Touchscreens are more fragile, so small accidents will harm their usefulness.
    • If there aren't any backup buttons, this can make navigating the device useless.
  6. They add weight to a device, making them potentially less appealing to carry around.
  7. Smaller screens and digital buttons are hard to touch accurately. Since our device is meant to be small, that is a major negative to consider.
  8. The user's hands and fingers can get in the way of information on screen.

Verdict

Based on these points, I don't think a touchscreen would benefit our device idea overall. We have a small list of features so they wouldn't clutter our design and be difficult to read, buttons are almost completely unneeded, and they aren't the absolute standard for an appealing device.
