| Is light disturbing ? |
|
Of course light can be disturbing. You will however not notice it during the night. You can postpone the first snapshot so that you can fall asleep without the computer disturbing you. |
|
| I do not have a powerbook. |
| Sure, that's a problem, buy one :-) or sleep in the same room with your desktop computer. This application was really designed for the new powerbooks with integrated iSights. |
|
|
|
| Are all computer lights off ? |
| The screen back-light is off. However, it is not possible to switch-off the power cord light programmatically, nor the green led on top of stand alone iSights. Just put a small black tape on it. |
|
| Is Sleep recorder recording all night sounds ? |
| Yes. You just have to adjust the sound detection level in the preferences, and all sounds over that level will be recorded. However, Dream recorder has a snoring detection, and you can choose to skip recording snoring. |
|
| I am not sleeping alone. |
| This happens. Dream recorder will not work as both persons motions will be detected. However, you can use it to prove that your partner is taking all the place in bed :-) A two people mode is foreseen in the next version. Try may be to place you computer on your side of the bed, at your level, so that the motion of your partner will be less visible. |
|
|
|
| Where should I install the computer ? |
| Around the bed. The night table is certainly the best place, but you could also put it at your feet. However, pressing the space bar to record dreams will not be so easy then ... |
|
| Why are the test image blurred ? |
| Dream recorder takes many pictures during a single snapshot, so if you move, it's blurred. During the night, you are at rest, it will not be blurred. Of course, if you move exactly during the snapshot, the picture will be blurred, but Dream recorder can handle that. |
|
| Is it scientific ? |
| Do not use Dream recorder for medical purposes. It is not accurate enough. However, yes, motions are related to sleep cycles. The reconstructed night profile is only a guess, not as precise as an EEG. |
|
|
|
| I am sleeping deep under the blankets. |
| Dream recorder will not be performing fully. However, your body profile will still be visible. |
|
| Do I have to wear a white tee-shirt ? |
| No, bare skin, any color, anything you want. However if you sleep with a black tee-shirt, in black sheets with a black night-cap, Dream recorder might not work properly :-) |
|
| Do I have to sleep in the dark ? |
| Most people do. However, if you are using a night light, you can turn the night vision enhancement off. Also, if you sleep with open curtains, Dream recorder will adapt itself to the changing luminosity of dusk and dawn. |
|
|
|
| Sleeping with my computer is a weird idea. |
| It is. But it is fun too :-) |
|
| What is lucid dreaming ? |
| ouh ... large question, actually the best is you have a look on Wikipedia. |
|
| Is it working only with iSights camera ? |
It works well with cameras that allow brightness control .... which is alas not the case for the new built-in iSights. You can plug any external camcorders. These will works (beware they have automatic switch-off modes).
For built-in iSights, as they have an automatic adjusment that cannoy be disabled, the best is you try, but without warranty.

|
| Brightness control does not work. |
Your camera does not allow brightness control then. This is the case for built-in iSights.
Some USB cameras have it, other haven't... |
|
| The screen backlight does not go off. |
| This is the case on iMacs. Turning the backlight off is not programmatically possible without super user priviledges. The screen becomes black at its lower intensity, but we cannot do more ... hopping this will not disturb you during the night. |
|
|
|
| The application is not working on my other Mac. |
| Sure. It is protected and uses the mac address of your computer for protection. Download it at new on the other computer for a trial. If you have bought the application, enter your code on every Mac. You can use it on three computers. |
|
| The night profile is flat |
| This can come from the fact that your camera is not well adjusted. Be sure you are always in its vision range. Be sure to have activated the night vision for dark environments. Use the test image to adjust parameters. |
|
| Images are all blurred. |
|
The iSight has an automatic focus. If you plug it in the dark, it could have some difficulties to adjust the focus. Plug it with light on. The focus settings will remain while you switch the lights off. |
