The embodiments described herein generally relate to a portable electronic device. The portable electronic device can include a processor and a sensor coupled with the processor, the sensor capable of detecting a stimulus, and responding to the stimulus by providing a detection signal to the processor. The portable electronic device can further include an interface unit capable of interacting with a user. The portable electronic device can further include a feedback unit in communication with the interface unit and the processor, the feedback unit providing a feedback response that is perceptible to the user during the interaction, where when the sensor detects the stimulus, the detection signal provided to the processor by the sensor causes the processor to respond by instructing the feedback unit to alter the feedback response.
