Assignment
We dove into a bit more detail about the broad picture elements of evaluative research. We broke down each major component of conducting evaluative projects, from variables and hypotheses to criterion and participant management.
For this reflection, I want you to select 2 solutions, the basic components of a research study in HCD, and break down all of the things you would measure and control for as follows in this example:
Sample Structure
Solution: Bluetooth Device Swapping in Smart Headphones
Independent Variable(s): Press-and-Hold Pairing vs. Menu Navigation
Dependent Variable: Speed, Error
Controlled Variables: Prior Experience with Bluetooth Devices, Age
Hypotheses:
• H1: Pairing speed will be significantly higher for Press-and-Hold Pairing than for Menu Navigation.
• H2: Error rate will be significantly higher in the Press-and-Hold Pairing condition than the Menu Navigation condition.
• H3: Prior experience with bluetooth devices will lead to more speed and fewer errors in the Press-and-Hold condition.
Methodology: In this evaluation study we will be having participants in a lab environment complete a series of tasks around pairing, un-pairing, and swapping control over Bluetooth devices (our menu navigation prototype vs. standard push-to-pair functionality). We will measure along metrics of speed and error to determine how successful our intervention is in simplifying the process of managing multiple smart devices in their interconnections. Participants will be debriefed post-experiment to gauge their opinions, frustrations, and preferences.
Analysis & Commentary: What are some of the issues you might predict? What elements to be aware of? Remember our discussions over stakeholder characteristics such as a fear of making a mistake, frustration, desire to please the experimenter, etc. How are we ensuring a smooth, efficient project? How are we comparing these measurements to one another. What values in our chosen variables will be able to confirm or reject our hypotheses? What do these hypotheses mean for the design and development of this solution?
