OVERVIEW

Vacuum cleaners are household items that can be found in almost every house in the United States. However, certain vacuum cleaner models prove to be inconvenient to use. In this report I analyzed the controls and displays of the Bissell ZING 2156 vacuum cleaner, and proposed redesign solutions.

​

The evaluation includes a walkthrough and analysis based on the stages of human factors in the product life cycle. For the first stage, Front-end Analysis, I conducted a user analysis of the target users regarding their characteristics as well as their goals. I also conducted a short function and task analysis of the appliance. Then, I analyzed the system specifications and functional requirements of the vacuum cleaner. In this section, I also examined the overall design of the vacuum, the controls, the displays, and the support materials such as the owner's manual. A heuristic evaluation was also conducted in order to understand potential usability issues. Design solutions to the usability issues were also included in this section. For the next stage, Implementation and Evaluation, I inspected several online user reviews to further understand any usability issues.

​

The operation and maintenance of the appliance was also examined, along with the method of disposal. The device was also evaluated based on the anthropometry of the target users, the principles of workspace design, and the energy expenditure and user capability.
