1. An apparatus comprising:
a display surface configured to present a real-time image of a user;
a light emitting portion comprising a plurality of light emitting diodes configured to convey semantic information to the user with light;
a sensor configured to measure a position of the user relative to the light emitting portion and configured to provide a signal that indicates the measured position of the user relative to the light emitting portion; and
a control unit coupled to the light emitting portion and the sensor, wherein the control unit is configured to determine semantic information regarding a quality of a personal care activity by the control unit monitoring performance of the personal care activity by the user, wherein the control unit is configured to control the plurality of light emitting diodes to express the quality as lit proportionate numbers of the plurality of light emitting diodes as the personal care activity of the user progresses and the control unit is configured to control the light emitting portion to minimize a shadowing and/or color-casting effect of the conveyed semantic information on the user and the presented real-time image of the user based on the measured position of the user relative to the light emitting portion.
