"Analogter" is an interactive and automatic calculation machine which simulates the interface and logic of Abacus, and above all, enlarges the analog process of Abacus to calculate the amounts of visitors in a performative form.

As a calculation process which needs to be well trained and once defined abacus as a efficient tool, nowadays literally causes hardly use of abacus. Compared to nowadays calculation technology operated by simple click by button, abacus enlarges the process of calculation in an analog way. The calculation process which used to be passively controlled by human is going to be designed as an interactive and automatic calculation installation calculating the amounts of visitors.

Set up:

1. Reconsider the key structure to make an abacus work, the rods are replaced by nylon lines and springs to connect beads which hence enlarges the analog performance of the process in a unpredictable way.
2. Nylon lines are used to connect the springs and beads, which controlled by stepper motors and are able to carry beads into a specific position towards horizontal beam then considered to be calculated.
3. Springs will responsible for the tension of beads which are not calculated, and fluctuant elasticities are generated during the calculation process which creates a unpredictable and analog performance.
4. Installation is to be hung on the roof in Bauhaus Digital Lab and a webcam is set to capture the amounts of visitors surround the installation.
