Stylus
Also known as: stylus pen, digital pen, touchscreen pen
A stylus is a pen-like tool used to write, draw, or tap on a touchscreen.
Basic 'passive' styluses act like a fingertip, while 'active' styluses, such as the Apple Pencil, Samsung S Pen, and Surface Pen, communicate with the device for pressure sensitivity, tilt, and palm rejection. They're popular for handwritten notes, signing documents, and digital art. While a stylus can make tablets feel like paper, each brand's pens usually only work with specific devices.
Stylus, explained at three levels
At home
A stylus is like a pen for your tablet or phone. You can write notes, draw, or tap small buttons more precisely than with a finger.
At work
Styluses let staff sign documents, mark up drawings, and take handwritten notes digitally.
At home
Check which stylus works with your device. Apple Pencil models only work with certain iPads, and Surface Pens work with many Windows touchscreen laptops.
At work
Active styluses support pressure sensitivity and palm rejection, useful for designers, engineers marking up plans, and field workers filling out forms.
At home
Handwriting recognition can turn notes into searchable text. In my opinion, a tablet and stylus can replace paper notebooks for many students.
At work
Standardize stylus models with devices to simplify replacements, budget for spare tips and lost pens, and confirm compatibility with apps used for signatures and annotations.
Real-world examples
At home
Lena takes university notes on an iPad with an Apple Pencil. She can search her handwritten notes later and highlight important sections.
At work
Jerome supports a Sudbury engineering firm. He equipped site inspectors with tablets and styluses so they could mark up drawings in the field.
How it compares
| feature | Active stylus | Passive stylus |
|---|---|---|
| Pressure sensitivity | Yes | No |
| Needs power | Usually | No |
| Compatibility | Specific devices | Most touchscreens |
| Price | Higher | Low |
Active styluses are precise and device-specific. Passive ones work anywhere.
For analysts
When digitizing paper forms, I'd test stylus workflows with actual field staff. Handwriting on glass feels different, and adoption depends on comfort.
History & origin
Light pens were used with computer screens as early as the 1950s, and Ivan Sutherland's Sketchpad program used one in 1963. Pen computers such as the GRiDPad in 1989 and Apple's Newton in 1993 used styluses, and the Palm Pilot in 1996 made them common for handheld organizers. Apple's iPhone in 2007 shifted the world toward fingers, but Samsung's Galaxy Note in 2011 revived the stylus with its S Pen, and Apple launched the Apple Pencil in 2015. Wacom tablets, from the 1980s onward, became the standard for digital artists. Samsung removed Bluetooth remote features from the S Pen on the Galaxy S25 Ultra in 2025, showing how makers keep rethinking pen features. In my view, the stylus is proof that old ideas return when the technology finally catches up.
