Recorders.

Rafael Lozano-Hemmer creates artworks that depend on your participation to exist. This exhibition records your pulse, fingerprints, voice and image, and these recordings form the actual content of the works. The content is entirely "crowdsourced", to use internet terminology. In this sense the works are playful, open and inclusive.

However, there is also a more ominous or predatory nature at play. The works use biometric and surveillance technology employed by governments and corporations to profile, control and predict our behaviours in the name of efficiency or safety. These tools have built-in prejudices, as when they are used for ethnic profiling.

In an age of reality TV, mobile computing, virtual economies, Google street view and credit databases, Lozano-Hemmer sees technology as an inevitable part of our culture. His approach is to "misuse" the technology to create experiences of connection and complicity by using ambiguity, irony, repetition, performance and self-representation.

I really enjoyed this exhibition. The idea that I was helping to contribute to the work that was on display was an interesting one. For me, tactile and interactive design is really important, and a quality that I want to incorporate into my own work more.
