ABSTRACT
This chapter examines intuitive interaction in the prototyping phase of a health-care product designed for the emerging market of sub-Saharan Africa by a Western multinational. This research focused on commercial product development, which entails small sample sizes used iteratively over multiple phases of the development cycle. The Cognitive Health Companion (CHC) kiosk was conceived by scientists at the IBM Research Africa (IBMRA) lab in Nairobi. The late-stage prototype CHC kiosk was undergoing product evaluation and was intended to assist in patient treatment of hypertension. The aim of In-Lab Usability Testing method was to evaluate participants' perceived value of the CHC kiosk as well as the efficiency of their interactions. Limited foundational research took place prior to the development of the CHC kiosk prototype. According to Spool (2005), this is common in Western multinationals and can lead to a large division in intuitive interaction design.
