Abstract
This paper defines requirements for entering text in interactive digital TV, based on theories of shared attention, in order to make a prototype of a remote control which enables more natural user interaction. The physical prototype of this newly created device features movement recognition and sensory feedback as modalities of interaction. In usability tests, data on users’ performance and satisfaction was collected, as well as data on their cognitive load (attention) and state of meditation (relaxation) captured through an Electroencephalogram device. The results showed that the solution, analyzed for a sample of 18 users, increased performance for typing long texts by 26.5%, raised satisfaction scores by 15%, relaxation scores by 29.4%, and maintained the users’ cognitive load when compared to use of an infrared remote control.
Highlights
The evolution of digital television and its connectivity capabilities are creating new possibilities for viewers to interact with television content
Bachmeyer [1] affirms that there are two trends in interactive digital TeleVision: the social iTV, where the viewer uses his/her iTV and its programs to socially interact through text; and the collaborative iTV, where the viewer uses his/her iTV to create new video content
The motivation for this research came from studies of new technological solutions to interact with the TV, which implement different modalities based on gestures, voice recognition, recognition of body movements, use of additional artifacts, etc., and of common remote controls used for inputting data in text format on the TV
Summary
The evolution of digital television and its connectivity capabilities are creating new possibilities for viewers to interact with television content. Bachmeyer [1] affirms that there are two trends in interactive digital TeleVision (iTV): the social iTV, where the viewer uses his/her iTV and its programs to socially interact through text; and the collaborative iTV, where the viewer uses his/her iTV to create new video content Both iTV trends present the common problem of data input. Several other studies, using voice [3], [5], gestures [6], touch in screen devices [7], or a combination of these modalities of interaction [8] proved to be either inefficient for large text input, or too costly for the mainstream market These solutions present problems linked to human factors (fatigue and cognitive effort) during long and simultaneous tasks.
