Novice–Expert+ Extension

This extension identifies usability issues with a website or web app. The extension logs the steps a user takes to perform a task and estimates the time an expert would take to complete each step. This information may be saved as a CSV file, so that novice and expert performance may then be compared. The novice time divided by the expert time is the novice–expert ratio. If this ratio is above the average, it could indicate a usability issue. The user can also determine Fitts' law constants to estimate expert pointing time for different input devices.

User reviews

Danny varghese (ID: 0000001c91da95be) Voted 5 ★ - Updated 10/28/2023 I was quite impressed with the use of 'novice-expert+' for user testing. Novice-Expert+ is a great Chrome plugin that makes evaluating the usability of websites and apps easier. It turns as a vital tool for identifying and improving usability problems by monitoring user activities and calculating expert completion times. It stands out due to its simple features and easy-to-use layout. The ease of exporting findings in CSV format, though, is what really makes it unique.I strongly recommend giving Novice–Expert+ a try since it is an excellent NEM evaluation tool that addresses a number of crucial parameters.

Sumukh Nagendra (ID: 000000500e67767f) Voted 5 ★ - Updated 09/13/2023 Novice–Expert+ is a useful Chrome extension that helps you evaluate how user-friendly a website or app is. It keeps a record of what users do and estimates how long an expert would take to do the same tasks. This can be super helpful to spot any issues and make improvements. I'd give it 5 stars because it provides valuable insights for enhancing usability.

Keerti Hegde (ID: 0000001f3a9a654f) Voted 5 ★ - Updated 09/06/2023 After using the Chrome extension 'novice-expert+' for user testing, I was highly impressed with its user-friendliness. The features it offers are straightforward and easy to comprehend. What particularly caught my attention and appreciation was the presentation of the final results in CSV format. I found it exceptionally convenient and valuable. I am considering sharing a detailed review to highlight the extension's ease of use and its effective presentation of results in CSV files. There are very few tools available for NEM evaluation. this one is must try.

Nisarg Rajpura (ID: 000000a4b9c834db) Voted 5 ★ - Updated 09/06/2023 Novice-Expert+ is a UX evaluation tool that has managed to redefine the way I approach usability testing and Novice-Expert Ratio calculations. As someone deeply immersed in the world of user experience design, I've come across my fair share of tools, but Novice-Expert+ has truly left a lasting impression. What truly sets Novice-Expert+ apart is its ability to calculate expert times using Fitt's Law. This feature is a game-changer, allowing for a more comprehensive understanding of usability and efficiency. The developers have put thought into creating a tool that caters to the nuanced needs of UX professionals. Adding times for System Response and "Think" times is intuitive and straightforward. The resulting CSV is not just a jumble of data but a neatly organized resource that enhances task exploration and analysis. There is a lot more you can do with this Chrome Extension, highly recommended.

Sagar Mhatre (ID: 000000e451d2bf89) Voted 5 ★ - Updated 10/15/2022 One way to measure the usability of a website or application is using KLM-GOMS, where the model predicts experts’ task execution times from keystrokes, pointer movements, thinking times, etc., which are compared with novice users’ task times to evaluate the efficiency of an interface. As a UX designer, I have previously used CogTool in combination with user event logging tools to make this comparison. However, my PC hardware, despite it being recent, was unable to run CogTool and logging software can be difficult to install for security reasons. In the end, I had to borrow someone else’s computer and manually insert each step in CogTool for each task that the user performed. In light of these issues, Novice-Expert+ is much more accessible because it is a Chrome browser extension: Apart from the browser requirement, which prevents Novice-Expert+ from logging user events on desktop applications, there are no hardware compatibility issues. Additionally, it logs all the user actions with time taken, and compiles it in a single CSV file, saving time and removing the potential for human error in creating a design storyboard in CogTool. Also, because of its accessibility, you can let users log their events remotely, thus removing the necessity of setting up a computer with logging software for user testing.
