Embodied Ubiquitous Learning Games (UELG) represent a new genre of technology-enhanced education in which learners interact with augmented physical environment to learn. The embodiment in such games comes from instrumented clothes based on e-Textiles incorporating sensors, actuators and low-power wireless modules. Designing and building such ubiquitous systems requires a complex interplay of conventional and embedded hardware and software co-design that includes novel elements like e-Textiles. In order to reduce the cost and shorten the development life-cycle this paper proposes the use of Software Product Lines (SPL). Towards this end, this paper borrows ideas from Architecture to present and apply a framework for constructing feature models for a Software Product Line for ULEG. The framework explicitly uses different types of features related to pedagogy, technology and domain of learning. A family of UELG based on a combination of problem posing and problem solving is used as an example to explain various components of the framework.
