Abstract
Techniques are disclosed for locking and/or unlocking a touch sensitive device using one or more stylus control features. For example, the stylus control feature may be a twistable top button knob. In some instances, the twistable top button knob may be rotated and/or depressed to lock a related device. In some other instances, the twistable top button knob may be used to unlock a related device using a unique rotation sequence, thereby providing a security mechanism. For example, the unlocking sequence may require a user to rotate the twistable top button knob in a first direction to a first reference point, in a second direction to a second reference point, and back in the first direction to a third reference point. The stylus may also include a feedback indicator, such as a multi-colored light-emitting diode (LED), that indicates the lock status of a related device, for example.
