I will start with a brief introduction to quaternionic Kähler and hyperkähler geometry and then outline the explicit construction of hyperkähler metrics described in a recent paper with Andrea Spiro, "On pseudo-hyperkähler prepotentials", J. Math. Phys. 57 (2016) 102501; https://arxiv.org/pdf/1502.07588.pdf
