Tablet Overview¶

Tablets connected to Zero Clients are provided additional support through the use of a tablet driver embedded into firmware that compensates for lag observed when the host operating system is a large distance from the Zero Client. The tablet driver works in tandem with the Remote Workstation Card Software for Linux or HP Anyware agents.

In some networks, users may notice a visible lag between the movement of the tablet stylus and the movement of the cursor on the display. This lag can be created by conditions such as large distances between client and host where stylus input coordinates must travel back and forth to the host before the cursor moves. This is considered a bridged configuration because the driver for the tablet is bridged to the host PC. To minimize the effects of the visible lag, we have embedded a tablet driver in PCoIP Zero Client firmware which reduces the distance required for data to travel between the stylus and local cursor. This allows better performance for users such as artists that work in graphic intensive environments. Supported tablets that can take advantage of this driver are described as locally terminated to the PCoIP Zero Client.

Supported Wacom tablets require the correct firmware uploaded to the PCoIP Zero Client as newer tablet models can be added to newer firmware releases. New supported tablet models can be identified by reviewing firmware release notes. To ensure you have the most complete set of supported Wacom tablets, use the latest release of PCoIP Firmware.

Absolute and Relative Co-ordinates¶

Supported tablets generally use absolute co-ordinates while in-session and relative co-ordinates while in pre-session such as when using the OSD. When using absolute co-ordinates, the local cursor will appear at the same position on the display as the stylus is on the tablet. As an example, if your stylus is at the center of the tablet, the cursor will appear at the center of your display. If using relative co-ordinates, the cursor will move a given direction and distance based on the motion the stylus moved across the tablet. As an example, if your stylus reaches the edge of the tablet, your cursor remains where it is on your display until you move your stylus from the edge and move it again starting at any point on the working tablet area.

Hosts¶

Bridged Wacom tablets are supported only in low-latency environments. Tablets in network environments with greater than 25ms latency will show reduced responsiveness and are not recommended.

Windows Workstations with a PCoIP Remote Workstation Card¶

PCoIP Zero Clients do not support locally terminating Wacom tablets when establishing a PCoIP session to a Remote Workstation Card installed in a Windows PC. Tablet communications are bridged to the Windows OS.

Linux workstations with a PCoIP Remote Workstation Card¶

PCoIP Zero Clients provides local termination to supported Wacom tablets when establishing a PCoIP session to a Remote Workstation Card installed in a Linux PC .

• Requires the installation of the supported version of the Remote Workstation Card Software for Linux with the Local Tablet Driver enabled.

Windows and Linux Virtual Machines with HP Anyware¶

PCoIP Zero Clients provides local termination to supported Wacom tablets when connecting to a supported version of a HP Anyware agent.

• Virtual Machines with HP Anyware host agents installed may have a limited list of supported tablets and may have special requirements for bridging of tablets and for local termination. For information on requirements for HP Anyware graphics or standard agents, please see the version of the host agent Administrators' Guide used in your deployment.

  • HP Anyware Graphics Agent for Linux

  • HP Anyware Standard Agent for Linux

  • HP Anyware Graphics Agent for Windows

  • HP Anyware Standard Agent for Windows

  • HP Anyware Standard Agent for MacOS
