Summary: Smartwatches are emerging device category that feature highly limited input
and display surfaces. We explore how touch contact areas, such as lines
generated by flat fingers, can be used to increase input expressivity in these
diminutive systems in three ways. Firstly, we present four design themes that
emerged from an ideation workshop in which five designers proposed concepts for
smartwatch touch area interaction. Secondly, we describe a sensor unit and
study that captured user performance with 31 area touches and contrasted this
against standard targeting performance. Finally, we describe three
demonstration applications that instantiate ideas from the workshop and deploy
the most reliably and rapidly produced area touches. We report generally
positive user reactions to these demonstrators: the area touch interactions
were perceived as quick, convenient and easy to learn and remember. Together
this work characterizes how designers can use area touches in watch UIs, which
area touches are most appropriate and how users respond to this interaction
style.
Summary: Crowdsourcing marketplaces provide opportunities for autonomous and
collaborative professional work as well as social engagement. However, in these
marketplaces, workers feel disrespected due to unreasonable rejections and low
payments, whereas requesters do not trust the results they receive. The lack of
trust and uneven distribution of power among workers and requesters have raised
serious concerns about sustainability of these marketplaces. To address the
challenges of trust and power, this paper introduces Daemo, a self-governed
crowdsourcing marketplace. We propose a prototype task to improve the work
quality and open-governance model to achieve equitable representation. We
envisage Daemo will enable workers to build sustainable careers and provide
requesters with timely, quality labor for their businesses.
