**6. Conclusions**

The research questions asked during this study were answered: the new artwork described above was able to use the *Z*-axis of holographic space to depict a chronological narrative; the new use of holographic space could be determined by an audience of experts in art and holography and the artwork had an a ffective impact on all the audience groups surveyed. The silent researcher critique proved a suitable new method to determine that research goals were met, and it will be used by the author when appropriate to evaluate the success of future artworks and exhibitions. The silent researcher critique may also benefit other practice-based researchers who need to obtain feedback from peers. A summative evaluation of audience experience was a necessary part of the research process both because the viewer produced the interactive artwork through their movement in front of it, and because their personal experience was needed to determine that the research goals were met and a contribution to knowledge confirmed (Edmonds 2010). The use of holographic space was perceived and described as novel by experts in art holography and it can therefore be argued that the research, which included both the production of new artworks and accompanying text, has contributed to the aesthetic development of the medium of holography.
