5. The method as claimed in claim 1 , wherein the light emitting portion comprises an adjustable optical arrangement and a plurality of light emitting elements that convey the semantic information, and the controlling comprises controlling the adjustable optical arrangement to change a light emission angle or focus of the light emitted by the light emitting elements based on the measured position of the user relative to the light emitting portion.

6. The method as claimed in claim 1 , wherein the method further comprises:

obtaining one or more images or a video sequence of the monitored personal care activity of the user of the apparatus;

analyzing the obtained one or more images or video sequence to determine a shadowing and/or color-casting effect of light conveying the semantic information on the user and/or to determine an evenness of lighting on the user; and

wherein the controlling comprises controlling the light emitting portion to minimize the shadowing and/or color-casting effect of the light conveying the semantic information provided by the light emitting portion 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 and the determined effect of the light and/or determined evenness of the lighting.

7. The method as claimed in claim 1 , wherein the method further comprises:

detecting an ambient light level or contribution of ambient light; and

wherein the controlling comprises controlling the light emitting portion to minimize the shadowing and/or color-casting effect of the semantic information provided by the light emitting portion on the user and the presented real-time image of the user based on the detected ambient light and the measured position of the user relative to the light emitting portion or the detected contribution of ambient light and the measured position of the user relative to the light emitting portion.

8. A tangible computer-readable storage media that is not a transitory propagating signal or wave, comprising control instructions for a method of operating an apparatus to convey semantic information to a user of the apparatus, the apparatus comprising a display surface configured to display a real-time image of the user, the method comprising:

determining a position of the user relative to a light emitting portion;

determining semantic information, regarding at least one of a timing and a quality of a performed personal care activity by monitoring the performance of the personal care activity by the user; and

controlling the light emitting portion to emit light to convey to the user the determined at least one of the timing and the quality of the monitored personal care activity, wherein controlling the light emitting portion comprises controlling the light emitting portion to minimize a shadowing and/or color-casting effect of the light conveying the semantic information on the user and a real-time image of the user presented on the display surface based on the determined position of the user relative to the light emitting portion.

9. The tangible computer-readable storage media as claimed in claim 8 , wherein the controlling comprises controlling the light emitting portion by adjusting a brightness or intensity of the light used to convey the semantic information based on the measured position of the user relative to the light emitting portion, and presenting the semantic information as an updated indication of at least one of the timing and the quality of the personal care activity as the personal care activity of the user progresses.

10. The tangible computer-readable storage media as claimed in claim 8 , wherein the light emitting portion comprises a plurality of light emitting diodes and the controlling comprises determining the quality of the personal care activity and controlling the light emitting portion to convey the determined quality as lit proportionate numbers of the plurality of light emitting diodes as the personal care activity of the user progresses.

11. The tangible computer-readable storage media as claimed in claim 8 , wherein the light emitting portion comprises a plurality of light emitting elements that convey the semantic information, and wherein the controlling comprises determining the timing of the personal care activity and controlling the plurality of light emitting elements to convey the determined timing as lit proportionate numbers of the plurality of light emitting diodes as the personal care activity of the user progresses.
