Virtual fixtures are virtual constraints that enhance human performance in motion tasks. They can either confine and/or guide a user's motion. In this paper, we use a commercially available motion platform to explore the portability and applicability of virtual fixtures and document how people interact with them. Two micromanipulation tasks are analyzed and the effects of similarly designed virtual fixtures are discussed. One task simulates a medical task, retinal vein cannulation, and the other simulates a manufacturing task, fine leads soldering. Preliminary experimental results show that the virtual fixtures increase the accuracy of both medical and manufacturing tasks, lending support to its portability and applicability across unrelated tasks
