The Internet has allowed market-based systems to become
increasingly pervasive. In this paper we explore the role of
user interface (UI) design for these markets. Different UIs
induce different mental models which in turn determine how
users understand and interact with a market. Thus, the intersection
of UI design and economics is a novel and important
research area. We make three contributions at this intersection.
First, we present a novel design paradigm which
we call hidden markets. The primary goal of hidden markets
is to hide as much of the market complexities as possible.
Second, we explore this new design paradigm using one
particular example: a P2P backup application. We explain
the market underlying this system and provide a detailed description
of the new UI we developed. Third, we present results
from a formative usability study. Our findings indicate
that a number of users could benefit from a market-based
P2P backup system. Most users intuitively understood the
give & take principle as well as the bundle constraints of
the market. However, the pricing aspect was difficult to discover/
understand for many users and thus needs further investigation.
Overall, the results are encouraging and show
promise for the hidden market paradigm.
