Writing device

摘要

The method involves comparing the collected biometric data with stored reference data in a data processing unit (4a) in a continuous manner and checking for a deviation opposite to the previously fixed reference data. A signal is directly generated with a deviation from the reference data, which leads to a haptic noticeable or acoustic response to the user directly in the writing device, as long as the deviation from the reference data continues. An independent claim is included for a writing device with stylus housing for executing the method.
