I have this problem on of my paragraphs in my document. There is a large blank space in between the first and the second word in the paragraph. Here is the code:
\documentclass[12pt, twocolumn, english]{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{babel}
\usepackage{enumitem}
\usepackage[margin=2.0cm]{geometry}
\usepackage{hyphenat}
\pretolerance=10000
\tolerance=2000
\emergencystretch=10pt
\begin{document}
\subsection{Haptic Devices}
\paragraph{}
Haptic interfaces are devices that uses the modality of touch for input and output in interaction. These devices provide better immersion and presence in virtual environments\cite{Tsalamal}, but also bridges issues of use when other sensory modalities are unavailable, such as vision for the blind\cite{Sjostrom}. Haptic devices that are either attached, or with limited or no direct contact are currently being explored \cite{Tsalamal}. Devices that are attached or provide limited contact allow more freedom but limited force rendering. A number of non-contact devices have promising, but share the issue of some of the limited-contact devices which is the restricted workspace\cite{Tsalamal}.
\end{document}
With this code the output looks like this:
As you can see there is a large gap between the first and the second word. Does anyone know how to prevent this from happening?

\pretolerance=10000. Try to comment it. – Jérôme Dequeker Jan 13 '17 at 13:15\pretolerance=10000to remove the hyphenations from the text. – martin36 Jan 13 '17 at 13:18\usepackage[none]{hyphenat}to suppress hypenations. – Jérôme Dequeker Jan 13 '17 at 13:21microtypeinstead. You will then reduce the numbers of hyphenation to a minimum, unless you write a lot of log words. Big, white spaces in the text is ugly, and reduce the readability of your text. If you insist not to use hyphenation, you should set your text ragged right. – Sveinung Jan 13 '17 at 13:35\lefthyphenmin=6would make it 6) – David Carlisle Jan 13 '17 at 14:27\lefthyphenmin=6to the document, but it still breaks a word after 2 characters. – martin36 Jan 13 '17 at 14:35
