A small terminal node with compuation and communication capability is a basic building block for IoT. It is deployed on every objects with sensors and low power wireless communication features and interacts with human as well as other physical or virtual objects. As such, it transmits collected information for IoT to provide intellectual services. Although the progress has been made consistently in sensor technology, human’s intermediate intervention is still required in the industries or the facilities critical for vigilance, security and inspection. Thus, a GUI support in terminal node is needed to make a correct and instant interaction with human. Because of the lightweight computing environment where the terminal node has very small size of storage as well as low performance in computation and communication, the trite GUI programming scheme that makes high computation and memory requirement is inapplicable to the terminal node. In this paper, two image data structures are presented to minimize space requirement of storage for character fonts. They do not reduce the storage requirement for fonts but also decrease communication traffic over the low power and lossy network.
