3. JUSTALK Justalk is a social mobile application. The application act as a conference as the context where strangers search and talk each other for a purpose. It is used for facilitating interpersonal and goal-oriented interaction
4. Problem Space •  Context of a conference •  People from different background with different profiles at a same place •  Difficulty in finding the perfect person with matching goals. •  Finding where the person could be exactly found •  When the person is free to talk
5. Design Process Conceptualization Paper Prototyping Internal Walkthrough Usability Testing High Fidelity Prototype Iterative Design
6. Where Justalk comes in Features of Justalk •  Sorting People with identical goals •  Finding where they are located •  Adding to the list of people so that they can be tracked in the real time •  If the user does not want to be found he can put off his visible status
7. Paper Prototypes
8. Prototypes Core Functionalities • Freedom of the user.
9. Prototypes Core Functionalities • Dialogue between the user and the application. (Like Siri but without voice)
10. Prototypes Core Functionalities • Retention rather than recall. (MyList)
11. Prototypes Core Functionalities • Provides exact location of the user without ambiguity.
12. Tasks The tasks evaluated: •  Task 1 You are a recruiter who is attending CHI 2013.You are having internship positions and is looking for students from IUPUI. •  Task 2 You are organizing IEEE conference on mobile application; you want to host an event in. Login and create an event. •  Task 3 You are a student. You would graduate soon and want a job. You are interested in Microsoft. You are attending CHI. Look in just talk that you can find if they are available in the conference. •  Task 4 Select how you can view all you have selected in a current session for talking to.

14. Usability Testing Demographics •  Performed evaluation of the prototype using quantitative methods and qualitative methods. •  Four Participants, IT and HCI Professionals •  Experts in their fields Tests were conducted remotely. Qualitative feedback was received on phone.
15. Question/Response SA A N D SD The concept of the product was clear through the interface. 2 2 0 0 0 The navigation of the product made sense to me in the context. 2 2 0 0 0 The interface was intuitive and could be easily understood. 2 1 1 0 0 The choices to made selections or filters in the product made sense to me. 0 4 0 0 0 The labels on the screen were easy to understand and had a flow. 2 1 0 1 0 The idea of locating people within a conference is interesting. 3 1 0 0 0 The user interface was consistent throughout the prototype. 1 2 1 0 0 SA: Strongly Agree A: Agree N: Neutral D: Disagree SD: Strongly Disagree Quantitative Post Task Questionnaire
16. Qualitative Feedback Feedbacks from interviews: •  The numbers next to the labels are not clear. •  Visible status is confusing •  Semantics issues in the context •  Issues with sorting
17. Qualitative Feedback Feedbacks from interviews: •  Graphics are not apt. •  There should be more options for visibility. •  Consistency in the interface, some of the interfaces allow multiple selections and some only allow single selections.
18. Conclusions •  Design Decisions followed each process •  Iterative Design Process was followed •  Graphically improved •  Ethical issues may be associated •  Future extension of the project for other contexts like informal contexts like parties for making new friends
