SIIG JK-WR0412-S1 - Features & Usage Impressions

The SIIG JK-WR0412-S1 is a wireless mini multimedia trackball keyboard. Using 2x AA batteries, it operates in the 2.4 GHz range and has an advertised range of 33 ft. The trackball is on the top right. In truly ergonomic fashion, there is a left click button on the top side of the frame which makes it easy to move the trackball and perform a left click operation simultaneously with a single hand. For the 'typical' living room scenario usage with both hands, there are left and right click buttons on the top left (similar to the IOGEAR keyboard covered in the previous section). However, unlike the IOGEAR keyboard, the scroll wheel is not on the top panel, but on top side of the frame (on the left side, right above the two mouse buttons).

The trackball resolution is set to 800 dpi and is not configurable.  The 2.4 GHz spectrum is pretty crowded, and, in order to prevent interference, the unit is capable of frequency hopping (with operation in 1 of 80 distinct channels). The unit has rubber soles for slip resistance. Unlike the IOGEAR unit, there is no explicit power switch (which is a drawback if you have a toddler active in your living room). However, for power saving purposes, the keyboard enters a sleep state after 8 minutes of inactivity. Only a keypress or mouse button click can bring it out of the sleep state. This is a bit frustrating in living room scenarios, where users tend to move the trackball first. The trackball itself is flimsier than the one on the IOGEAR unit. They main keys are also smaller than the standard size that we encountered on the other units. This might make fast typing difficult for those used to standard keyboards, though that is probably not the primary use case for this keyboard.

In terms of keyboard layout, the Fn key and Ctrl key on the bottom left are switched from the usual, which may result in the user inadvertently mistyping key combinations. Another unfortunate aspect of the keyboard layout is the fact that a numeric keypad is embedded in the main keypad, and it is controlled by the NumLock key. Most computers boot with the NumLock key turned on, resulting in the users typing in numbers instead of the intended letters. In case of passwords, the user might not even realize the mistake. It would be nice to have an indicator on the device for this purpose. That said, PCs usually have a BIOS setting to turn off this feature. The problem turned out to be bad enough for SIIG to issue an addendum [PDF] to the user manual [PDF].

The trackball has a red glow underneath when the unit is in the active state. This provides an easy way to identify whether a keypress or mouse click needs to be made, but might also be disconcerting in a dark room (a frequent HTPC usage scenario). The ergonomics and intuitiveness of the keyboard and the mouse buttons / scroll wheel layout, as well as the larger number of special keys, are the positives for the device.

    A thumb based HTPC keyboard/mouse article would be great! Reply

    Just about to post the same:) If your more navigating, with occasional keyboard usage, then its far smaller. Reply

    Yep. Been using one for years and it is just about perfect. Reply

    I have one of those, it kind of sucks. It's awkward to use. Reply

    I have three of these. One word of caution, do not put the dongle in a USB3 powered port... cooked one (fire). Works great in USB2 though. Love it otherwise. Reply

    I like to use that Lenovo remote AND a regular wireless keyboard and mouse. The best of both worlds. Reply

    Not sure if this is a big enough niche, but how about pointing devices for Windows 8.x-based HTPCs? I had to add Start8 and ModernMix to Win8 to make it usable as a desktop PC, but I think Modern/Metro works great as an HTPC interface.

    I'd like to see the various wireless touch mice, trackpads, a regular scroll wheel mouse, etc. reviewed in an HTPC context. I use Logitech K810 (which is outstanding) and a Logitech T620 mouse, which is meh.

    You might also add the Logitech TK820 to this comparison.

    Unified remote (http://www.unifiedremote.com) is a very decent option, especially if used with a tablet. An IOS version is promised soon. Reply

    Unified remote is pretty awesome even with just the free version. The pulse eight CEC adapter plus Unified Remote for the situations where you need qwerty or mouse input (pretty much just software updates) is the ideal solution for me. Reply
