In this paper, we propose a natural user interface evaluation method (NEM) based on reality framework. This method defines evaluation criteria based on reality framework, extracts features from multi-source data, utilizes AHP method to construct a weight model, and finally provides integrated evaluation result. This paper takes pen-based user interface, one of the most representative NUIs, as an example. We evaluate Tilt interaction tasks based on NEM and get the multi-dimensional integrated evaluation results, which provide design guidelines for Tilt Interaction. It demonstrates that NEM can effectively embody the features of NUI and broaden evaluation bandwidth, and can be used to guide the design and evaluation for NUI as well.
