Enhancing interactivity with transcranial direct current stimulation

Transcranial Direct Current Stimulation (tDCS) is a non-invasive type of neural stimulation known for modulation of cortical excitability leading to positive effects on working memory and attention. The availability of low-cost and consumer grade tDCS has democratized access to such devices allowing us to explore its applicability to HCI. We review the relevant literature and identify potential avenues for exploration within the context of enhancing interactivity and use of tDCS in the context of HCI.
