Conceptual Design Basic Concept: User Interface for large,
touch and voice command capable displays, to be used in parts of
the house where people do various household and personal
activities. Goal: To make the task of looking up relevant
information in various areas of the home, easy, efficient and to
create an overall enjoyable experience.

Questionnaire Results Activities: Preparing Food, Personal
Grooming, Working on Equipment, Eating Physical and Cognitive

Slide 8
Based on Results Need to segregate the program into contexts
(Kitchen, Garage, Bathroom) Needs to be capable of supporting some
type of music player and possibly other desired media applications.
Must be able to view static content and have capabilities to view

cooking video button was confusing 3.Wanted more navigation options
on recipe widget 4.Preferred instructional videos to be
contextualized in recipe viewer, even associated with individual

Slide 21
Audio / gesture desirability - users want to use voice commands
and gestures We added "speakable screen" indicator and "speakable
item" indicators on UI elements 1
Slide 22
The Media button was confusing We added an "add widget" button
and integrated the Music and other media as regular widgets 2
Slide 23
Users wanted more navigation options on recipe widget We are
expanding category and ingredient search options 3

Users preferred instructional cooking videos to be
contextualized in recipe viewer, even associated with individual
steps We're adding embedded video into the recipe viewer itself,
rather than having a separate instructional video button 4
Slide 25
Walkthrough showed necessity for full-screen view So, we added
full-screen option to recipe viewer widget 5
