KLM helps us predict how long it takes to complete tasks. In our example, can someone tell me the first step a user takes?
They mentally decide to copy the selected text.
Right! This is counted as a mental preparation phase. What about the physical actions that follow?
Moving the mouse to the selected text and right-clicking to open the context menu.
Absolutely! Each of these actions is broken down into operators, allowing us to assess the efficiency of the overall process. Let's see how we calculate the total execution time.

Overview of the Mouse-Centric Copy-Paste Approach
The mouse-centric copy-paste method utilizes context menus for performing operations, which many users find intuitive. This analysis employs the Keystroke-Level Model (KLM) to quantitatively evaluate the efficiency of executing a copy-paste task using the mouse, illustrating each step involved in the process. By highlighting user actions, mental preparation moments, and the average time required for each operation, we aim to provide insights into the effectiveness and efficiency of the mouse-centric approach compared to keyboard-centric and hybrid strategies.
The KLM Application in Context
KLM, a predictive model that estimates the time for expert users to perform routine tasks, informs this analysis. Each action is categorized into operators (e.g., Mouse movements, Keystrokes) and the corresponding timeframes are applied to calculate the total execution time.
Detailed User Action Sequence
The user action sequence includes deciding to copy, using the right-click context menu, performing a paste action, and all resulting operations culminating in the total execution time of approximately 10.4 seconds plus system response time. By assessing the mouse-centric method this way, we gain valuable perspectives on user efficiency in interaction design.

The user performs the entire copy-paste operation using only the mouse and context menus.
Detailed Explanation
This chunk introduces how the copy-paste function operates solely using mouse controls. Users are assumed to select text, right-click to open a context menu, select the 'Copy' option, and then paste the text using the mouse again. This method simplifies interactions by not incorporating keyboard shortcuts.
Examples & Analogies
Imagine you are preparing to copy a phrase from an email. You highlight the text with your mouse, right-click to open a menu, select 'Copy', and then navigate to where you want to place it, right-click again, choose 'Paste'. This mirrors the action of using a recipe card: finding a recipe, writing it down (Copy), and later reading it back to recreate the dish (Paste).
User Action Sequence (Decomposition)

- Mentally decide to copy the selected text.
- Move mouse cursor over the selected text.
- Right-click mouse button (to open context menu).
- Mentally scan / identify the "Copy" option in the context menu.
- Move mouse cursor to the "Copy" option.
- Left-click "Copy" option.
- System processes the copy command (brief system response).
- Mentally decide where to paste the text.
- Move mouse cursor to the desired paste location.
- Left-click at the paste location (to set insertion point).
- Right-click mouse button (to open context menu at paste location).
- Mentally scan / identify the "Paste" option in the context menu.
- Move mouse cursor to the "Paste" option.
- Left-click "Paste" option.
- System pastes the text (system response).
Detailed Explanation
This chunk outlines the specific sequence of actions a user takes to copy and paste text using a mouse-centric method. It emphasizes the cognitive steps involved, such as deciding to copy, identifying options in menus, and moving the cursor to various locations. Each action is vital for the overall execution of the task, showing how multi-step and interactive this method is.
Examples & Analogies
Consider giving someone detailed instructions to complete a task: you first explain what they should do, guide them to the right tools, and help them navigate through various steps. This mirrors how a user interacts with the software, deciding what to do at each point, much like guiding a friend through a complex procedure like assembling furniture.
KLM Operator Sequence (with 'M' Heuristics Applied)

- M (decide to copy using context menu)
- P (move mouse to selected text)
- B (right-click to open menu)
- M (identify 'Copy' option in menu)
- P (move mouse to 'Copy' option)
- B (left-click 'Copy')
- R (system processes copy)
- M (decide where to paste, then decide to use context menu for paste)
- P (move mouse to paste location)
- B (left-click to set insertion point)
- B (right-click to open menu)
- M (identify 'Paste' option in menu)
- P (move mouse to 'Paste' option)
- B (left-click 'Paste')
- R (system pastes text)
Detailed Explanation
In this chunk, KLM operators are specified to categorize user actions into different types: 'M' for mental decisions, 'P' for pointing movements, 'B' for button clicks, and 'R' for system responses. This structured approach helps to analyze the interaction in detail, making it clear how each step contributes to the overall efficiency of the copy-paste operation.
Examples & Analogies
If you think of driving a car, you have to mentally decide to go (M), turn the steering wheel to navigate (P), and press the accelerator (B) to move forward. Similarly, in this copy-paste operation, each KLM operator corresponds to a distinct step in the task, just like the steps needed to drive safely.
Calculation of Estimated Execution Time for Alternative 1

- Count the operators:
- 'M': 4
- 'P': 4
- 'B': 6 (3 right-clicks, 3 left-clicks)
- 'R': 2 (system copy, system paste)
- Summing times (using average values: M=1.35s, P=1.1s, B=0.1s):
- Total Time = (4 * 1.35) + (4 * 1.1) + (6 * 0.1) + 2R
- Total Time = 5.4 + 4.4 + 0.6 + 2R
- Total Time (Alternative 1) = 10.4s + 2R
Detailed Explanation
This chunk details the process of calculating the total execution time for using the mouse-centric method for copy-paste. By counting each operator and applying the average times, a total time for the task is derived. This quantitative approach highlights how complex user interactions can be analyzed and compared, emphasizing the benefits of model-based design in optimizing user interfaces.
Examples & Analogies
Imagine you are budgeting for a trip. You would list your expected expenses (like travel, food, lodging) and then sum them up to get your total cost. Similarly, calculating execution time uses a detailed breakdown of each action step and accumulates all those parts to determine the overall time needed for the entire copy-paste task.
