Results of Data Collection and Analisys
After both tests the subject were asked for feedback in the form of a questionnaire as well as in the form of an interview. Furthermore a Video of the subjects has been made and a screen capturing performed in order to reproduce the user interaction for evaluation purposes. Through the tests the system automatically gathered metrics of the user interaction.
The analysis and the evaluation of the results is divided into two parts: (1) The evaluation consists of the data interpretation of the performed usability studies and (2) the evaluation of the application.
The usability outcomes showed for the different input devices an expected fast interaction with the use of the hand mouse. The interaction with the dataglove showed as well good results in such environments. The subjects felt quite comfortable with the dataglove, but gave also good hints for the improvement of the usability. They were disappointed about the difficult use of the speech navigation and its behaviour especially with background noise.
Output modalities were rated best for the (still-) image output. The usability test results of the performance measurements prove this result, although the video output performed also well.
The evaluation of the whole application was tested with 10 subjects. This test gave information about the wearable application and integrated components that were used for the usability study. It revealed information about the structuring of the content and the use of the dataglove. These outcomes will be taken into account for the upcoming tests at the workers’ premises in order to gain valuable results for the application itself and the whole development process as well.
