Exploring Grahpical Feedback in a Demonstrational Visual Shell
نویسندگان
چکیده
We present a visual language that serves as a novel form of feedback in a Programming by Demonstration (PBD) interface. The language explicitly represents data, such as les, with unique icons and implicitly represents operations by changes to data icons, so that operations reeect the changes seen in the interface when executed. In addition, the language is used to provide feedback to the user by indicating loops and inferred sets, specifying parameters, etc., and is integrated into other parts of the PBD system, such as the editor. This forms a close union between the interface, the PBD system and the program representation and helps bridge the gap between the user's mental model of the programming process and the actual programming task.

The Demonstrational Interfaces Project at CMU
The Demonstrational Interfaces Project at CMU has been investigating various aspects of demonstrational interfaces for the last eight years. During this time, we have created six interactive software building tools that use demonstrational techniques, as well as an architecture to support demonstrational programming in general. In addition, we have created a demonstrational Visual Shell (iconic...
متن کاملExploring Different Oral Corrective Feedback Preferences: Role of Intrapersonal and Interpersonal Intelligences
This study explored corrective feedback (CF) types and their relationship to L2 learners’ intelligence types. Participants were 60 intermediate L2 learners aged 18-29 in Isfahan, Iran. Based on their intelligence types as intrapersonal and interpersonal, the participants were divided into 2 groups. McKenzie’s MI Inventory (1999) and a researcher-designed questionnaire on CF types were employed....
متن کاملBelievable Visual Feedback in Motor Learning Using Occlusion-based Clipping in Video Mapping
Gait rehabilitation systems provide patients with guidance and feedback that assist them to better perform the rehabilitation tasks. Real-time feedback can guide users to correct their movements. Research has shown that the quality of feedback is crucial to enhance motor learning in physical rehabilitation. Common feedback systems based on virtual reality present interactive feedback in a monit...
متن کاملInvisible Programming
The topic of this conference is Visual languages, but I want to discuss computer programming using a technique where there is no apparent language at all; the language is (mostly) invisible. Here, the user sees the results of the program aecution and the data the program is operating on, but the program itself is not shown. The program is specifcd by demonstrating the operations that should be ...
متن کاملExploring the Role of Occurring Errors Distribution in the Distribution of Corrective Feedback Targets
This study attempted to compare corrected linguistic errors in foreign language classrooms and all errors occurring in these classes to see which types of errors are more attended to by teachers in relation to their occurrence in classes. For this purpose, 69 hours of the classes of 34 teachers teaching in different language schools were recorded and the errors corrected by these teachers were ...
