Using the Relative Mouse Feature for CAD and 3D
Applications
If you use the VMware Blast display protocol or the PCoIP display protocol when using CAD or 3D
applications in a remote desktop, mouse performance improves when you enable the relative mouse
feature.
In most circumstances, if you are using applications that do not require 3D rendering, Horizon Client
transmits information about mouse pointer movements by using absolute coordinates. Using absolute
coordinates, the client renders the mouse movements locally, which improves performance, especially if
you are outside the corporate network.
For work that requires using graphics-intensive applications, such as AutoCAD, or for playing 3D video
games, you can improve mouse performance by enabling the relative mouse feature, which uses relative,
rather than absolute, coordinates. To use this feature, select Options > Enable Relative Mouse from the
Horizon Client menu bar.
Note If you use Horizon Client in windowed mode rather than full-screen mode and the relative mouse
feature is enabled, you might not be able to move the mouse pointer to the Horizon Client menu options
or move the pointer outside of the Horizon Client window. To resolve this situation, press Ctrl+Alt.
When the relative mouse feature is enabled, performance might be slow if you are outside the corporate
network, on a WAN.
Important To use this feature, a Horizon administrator must turn on 3D rendering for the desktop pool.
For information about pool settings and the options available for 3D rendering, see the Setting Up Virtual
Desktops in Horizon 7 or Setting Up Published Desktops and Applications in Horizon 7 document.
Using Scanners
With the scanner redirection feature, you can scan information into remote desktops and applications with
scanners that are connected to the local client system. This feature redirects scanning data with a
significantly lower bandwidth than can be achieved by using USB redirection.
Scanner redirection supports standard scanning devices that are compatible with the TWAIN and WIA
(Windows Image Acquisition) formats. Although you must have the scanner device drivers installed on the
local client system, you do not need to install the scanner device drivers on the remote desktop operating
system where the agent is installed.
If a Horizon administrator has configured the scanner redirection feature, and if you use the VMware Blast
display protocol or the PCoIP display protocol, a scanner connected to your local system can be used in a
remote desktop or application.
Important Do not connect a scanner from the Connect USB Device menu in Horizon Client. The
performance will be unusable.
