A company deploys tablets for field workers to capture signatures on glass screens using a capacitive stylus. Several workers complain that the stylus does not register consistently. What is the most likely cause?
Trap 1: The screen protector is too thick.
A thick screen protector can reduce sensitivity, but the primary issue is the stylus type, not the protector.
Trap 2: The tablet's touch calibration is off.
Touch calibration issues affect all input, not just a specific stylus; the stylus works inconsistently, suggesting a compatibility problem.
Trap 3: The workers are pressing too lightly.
Capacitive screens detect touch through electrical field changes, not pressure; pressing harder does not improve detection.
- A
The screen protector is too thick.
Why wrong: A thick screen protector can reduce sensitivity, but the primary issue is the stylus type, not the protector.
- B
The stylus tip is not conductive.
Capacitive screens rely on electrical conductivity; a non-conductive stylus tip will not be detected.
- C
The tablet's touch calibration is off.
Why wrong: Touch calibration issues affect all input, not just a specific stylus; the stylus works inconsistently, suggesting a compatibility problem.
- D
The workers are pressing too lightly.
Why wrong: Capacitive screens detect touch through electrical field changes, not pressure; pressing harder does not improve detection.
