+The Plan 9 operating system has a specific idea for user interaction and user interfaces.
+In general, many aspects are thought-through and provide a mostly consistent look and feel throughout the whole operating system.
+However, all user interaction components are designed for a standard computer screen in mind, paired with keyboard and mouse for interaction.
+In this paper we will explore different challenges we encounter when designing a specialized touch user interface for Plan 9 systems.

+
+# Why do we need a touch user interface?
+
+Hello World.
+
+Next paragraph.
+
+Actual contents:
+
+- Many modern computer systems come with touch screens only, without traditional input methods.
+
+# Why do we need a Plan 9-specific user interface?
+
+- Plan 9 OS is much different than other OSes.
+- It has very specific idea of IPC, user interaction and what a computer is.
+
+# Challenges
+
+## Well-known user interface challenges
+
+- Different screen sizes (phone, tablet, much bigger differences than on PC).
+- Touch challenges (thumb size, multi touch, ...).
+- Probably nothing new, refer to existing documents.
+
+## Three pillars of user interfaces on Plan 9
+
+### Text interface
+
+- shell interface
+- rio/window
+
+### Graphics
+
+- devdraw
+
+### Mouse interaction
+
+- mouse chording
+- rio/window integration
+
+## Integrated system components
+
+### Plumber
+
+- How plumber is important for Plan 9 UI
+- It should be natively integrated and feel natural to use it.
+
+### Namespaces
+
+- How to visualize and manage namespaces on Plan 9, using touch UI.
+- Dynamic, per-process namespaces are an integral part of Plan 9.
