By using techniques such as the Wizard of Oz (WoZ) and video capture, this paper evaluated the performance of the Nao Robot in the role of a personal assistant, which was valuated alongside the impact of the assigned gender (male/female) in the perceived performance of the robot assistant. Within a sample size of 39 computer sciences students, this study assessed criteria such as: perceived enjoyment, intention to use, perceived sociability, trust, intelligence, animacy, anthropomorphism, and sympathy, utilizing testing tools such as Unified Theory of Acceptance and Use of Technology (UTAUT) and Godspeed Questionnaire (GSQ). These methods identified a significant effect of the gender assigned to the robot in variables such as intelligence and sympathy.
Children born in the Information Age are digital natives; this characteristic should be exploited to improve the learning process through the use of technology. This paper addresses the design, construction, and evaluation process of TITIBOTS, a programming assistance tool for mobile devices that allows children in the early childhood to create programs and execute them using robots. We present the results of using TITIBOTS in different scenarios with children between 4 and 6 years old. The insight obtained in the development and evaluation of the tool could be useful when creating applications for children in the early childhood. The results were promising; children liked the application and were willing to continue using it to program robots to solve specific tasks, developing the skills of the 21st century.
This paper describes the design and evaluation process of two mobile programming assistance tools that allow children in the early childhood to develop programs and execute them using robots. The tools are called TITIBOTS and TITIBOTS Colab which incorporates collaboration. The tools have icon-based interfaces and integrate visual programming, robotics, and mobile devices as one tool. The main issues and lessons learned during the design process are described. The methodology used in this project was User-Centered Design (UCD) process. The tools were developed and evaluated applying participatory-design, experience prototyping, and usability testing. The final product are two simple, intuitive, and easy to use tools, for children between 4 and 6 years old. The results were promising: children liked the applications and were willing to continue using it to program robots for solving specific tasks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
