Mining the usage patterns of ROS primitives

Andre Santos, Alcino Cunha, Nuno Macedo, Rafael Arrais, Filipe Neves dos Santos
2017 2017 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS)  
To quantify the severity of this problem, we have mined a large number of existing ROS packages to understand how its primitives are used in practice, and to determine which combinations of primitives  ...  To ensure the (much needed) dependability and safety of such applications we forecast an increasing demand for ROS-specific coding standards, static analyzers, and tools alike.  ...  The results are exported in CSV format, to ease inspection and manipulation in a spreadsheet editor.  ...

Progression of tool usage in project-based IT courses

Justyna Szynkiewicz, Robin I. Munkvold, Line Kolas
2020 2020 IEEE Frontiers in Education Conference (FIE)  
The analysis of these data has led to a classification of the tools used by students in PjBL and guidelines for ensuring progression of tool usage in course design and study program design.  ...  The data was further analysed through a "lens of progression", resulting in guidelines for study program designers and course designers, with the goal of quality assuring the tool implementation and usage  ...  In the beginning, a student tries to understand a given task and come up with possible solutions. Secondly, he or she decides which solution to use and makes a plan of action.  ...

Managing Corporate Portal Usage with Recommender Systems

Helmuth Elsner, Jan Krämer
2013 Business & Information Systems Engineering  
In this article, we propose a recommender system for corporate portals in order to increase service awareness and usage.  ...  Corporate portals are supposed to support a company's business model and to increase productivity of the employees.  ...  Taken together, this necessitates a solution which is capable of deriving relevant service recommendations bottom-up (i.e., through inferences from the portal's usage), rather than top-down (i.e., through  ...

A Need-finding Study for Understanding Text Entry in Smartphone App Usage [article]

Toby Jia-Jun Li, Brad A. Myers
2021 arXiv   pre-print
Text entry makes up about one-fourth of the smartphone interaction events, and is known to be challenging and difficult.  ...  However, there has been little study about the characteristics of text entry in the context of smartphone app usage.  ...  This lack of knowledge makes it hard to properly evaluate if a proposed solution to text entry problems is relevant.  ...
