On screen options
Along the bottom of the screen are four icons: a camera, an open rectangle representing a screen, a list icon, and an icon that kind of looks like two keys that when selected will bring up the Preferences screen. Selecting one of these icons will bring up the associated function. For example, if you tap the View icon, you will see the last image that you captured. Pressing the Visor's scroll buttons while in this mode will switch you between images. Selecting the Image List, shown in Figure B, will bring up a list of all the images on the Visor along with their resolution. The Preferences icon will enable you to set a default resolution, category, and whether or not you want to be prompted to save an image.

Crash problems
So how well does the eyemodule work? I had it up and running and my first three images stored in about five minutes. It's really that easy. I had no problems with the unit till it came time to remove it from my Visor.

When I removed the eyemodule from my Visor, I wound up with either a Datamgr or Filemgr crash. This happened around 45% of the time. Most of the time, I was able to do a soft reset and not lose any data. However, one time I had to do a hard reset. Thankfully, I'm religious about backing up my Visor to the back-up module.

I then tried using the eyemodule on a clean Visor and had absolutely no problems. I reloaded all my applications and had no problems. Then I reinstalled Hackmaster and all of my hacks. Bingo! Crash goes the Visor. I deactivated all the hacks and the eyemodule worked fine. I have not set about trying to determine which hack causes the crash, but a word of warning is in order here. You may want to disable your hacks before using the eyemodule.

Picture quality
By now you are probably asking yourself, "So how do the pictures look?" To be honest, I wasn't too impressed with them. They are grainy, out of focus, and in the larger size images, object edges have a zippered look. To compare the three resolutions, I took three pictures. All of them were taken of the same subject at the same time from the same location. All that changed was the resolution of the shots. Figure C shows the room in 160x120 pixel black and white.

FIGURE C

Here's a room photographed in the 160x120 pixel black and white resolution.

Figure D shows the same room in the 320x240 pixel black and white resolution.

Here's the room photographed in 320x240 pixel black and white resolution. Roll over picture for a larger image.

Finally, Figure E shows the room in the 320x240 color resolution.

In these examples, you can see the grainy quality of the image. Nighttime and low light pictures are even worse.

Positives
There are several nice features on the eyemodule I did like. For example, you can set a timer and capture a single image, or you can capture a series of images on a timed basis. I could think of several uses for this. Another feature I liked is the fact that you can beam an image to any other Palm device, even if it doesn't support the camera itself. Eyemodule allows you to beam the viewing software along with the image. You can also attach notes to an image, which allows you to keep track of what each picture is.
