5 Tips for Better Handwriting Recognition
Getting clean, accurate LaTeX from handwritten math doesn't require perfect penmanship. But a few simple habits can dramatically improve your results.
1. Use Dark Ink on Light Paper
High contrast is the single biggest factor in recognition accuracy. A dark pen (black or dark blue) on white or light paper gives TexPixel the clearest signal. Pencil works too, but press firmly.
2. Give Symbols Room to Breathe
Cramped formulas are harder for both humans and AI to read. Leave clear gaps between:
- Fraction bars and the expressions above/below them
- Subscripts and superscripts and their base symbols
- Parentheses and the terms they enclose
3. Be Deliberate with Similar Characters
Some characters are notoriously ambiguous in handwriting:
- 1, l, | — make your ones with a serif or flag
- 0, O, o — zeros should be narrower and more oval
- x, × — use a clear multiplication dot (·) when you mean "times"
- u, v — round bottom vs. pointed bottom
4. Keep Your Camera Steady
If you're photographing notes with a phone:
- Hold the phone parallel to the paper (not at an angle)
- Make sure the lighting is even — no harsh shadows across the formula
- Get close enough that the formula fills most of the frame
5. One Formula Per Upload
TexPixel works best when each image contains a single formula or a closely related set of expressions. If you have a page full of equations, crop them individually for best results.
With these habits, you'll see noticeably better accuracy — often 95%+ even for complex handwritten expressions.
