  • 2011–2012 APPA National Pet Owners Survey U.S. pet-ownership estimates • Dogs • 78.2 million—Number of owned dogs • 46 percent—Percentage of households that own at least one dog • 60 percent—Percentage of owners with one dog • 28 percent—Percentage of owners with two dogs • 12 percent—Percentage of owners with three or more dogs • 1.7—Average number of owned dogs per household • 21 percent—Percentage of owned dogs who were adopted from animal shelters • $248—Average annual amount spent by dog owners on routine veterinary visits • 78 percent—Percentage of owned dogs who are spayed or neutered • Even—Proportion of male to female owned dogs • Cats • 86.4 million—Number of owned cats • 39 percent—Number of households that own at least one cat • 52 percent—Percentage of owners with more than one cat • 2.2—Average number of owned cats per household • 21 percent—Percentage of owned cats who were adopted from an animal shelter • $219—Average annual amount spent by cat owners on routine veterinary visits • 88 percent—Percentage of owned cats who are spayed or neutered • 80 percent vs. 65 percent—The difference in number of owned female cats and owned male cats, respectively http://www.humanesociety.org/issues/pet_overpopulation/facts/pet_ownership_statistics.html

  • Direct precedents
  • Which one is better?
  • Who is the target user?
  • History, Precedents and Inspiration - AIBO
  • History, Precedents and Inspiration - PLEO
  • History, Precedents and Inspiration - PARO
  • “Paro has the appearance of a baby harp seal. Previous attempts to develop cat-robot and dog-robot (Shibata et al., 1999) demonstrated the inadequacy of these models in supporting interaction dynamics. The physical appearance of these robots turned out to be unsuccessful in meeting human being expectations during the interaction. The unlikeness from real cats and dogs was so evident to compromise any possibility of engagement with the robots. The baby seal model was therefore attempted. The choice was inspired by the idea to reproduce an unfamiliar animal that could barely create expectations in the human agent during the interaction. The design of Paro tried to balance the need to guarantee the likeliness with a real baby seal with the capability to stimulate exploration and sustain interaction. In this perspective a considerable effort was devoted to the design of eyes and gaze and all the facial expressions in general. The body is equally harmonious and balanced in all its parts. In designing Paro, a particular attention was devoted to create an impressive tactile experience…”

  • Defining the Problem – Key Questions The engineering design process starts with the problem at hand: • What is the problem or need? • Who has the problem or need? • Why is it important to solve? • [Who] need(s) [what] because [why].
  • Defining the Problem - Tools
  • User, Context and Precedents For an engineering design project, background research focuses on two major areas: • Users and context • Precedents
  • Tools for User and Context Needs Usage Data Formal Observation InterviewFocus Group Survey
  • Tools for Precedent Analysis Existing Products Academic Prototypes / Publications Patents Bio-Inspired
  • Establishing the Design Requirements Specify Requirements: Design requirements state the important characteristics that your solution must meet to succeed. One of the best ways to identify the design requirements for your solution is to analyze the concrete example of a similar, existing product, noting each of its key features. Design Brief – A Tool for Establishing Design Requirements • A description of the target user. • A definition of the problem to be solved. [Who] need(s) [what] because [why]. • A description of how existing products are used and why they fail to address the problem. • A list of all the requirements for the proposed design. Types of Design Requirements Cost - Purchase, Use, Repair,… Geometry - Size, Curvature,… Physical Characteristics - Weight, Density, Colour, ….. Input - Energy, Gas, Labor,…. User Requirements - Use, Learning, Training, ….. Aesthetics - Style, Colour, Texture,….. Performance - Accuracy, Strength, Speed,….. Output - Pollution, Side effects, Power,…. Environmental Requirements - Temperature, Corrosion,….
