My great problem is that I'm constantly "feeding" washing machines with my cell phones, watches, keys, etc. My idea is to provide laundry rooms or washing machines themselves with X-ray or some other method to detect electronic devices before they start running.

I travel a lot and often use my digital camera to take pictures of landmarks and the landscape. All the pictures are time stamped to tell me when they are taken but there is no information on where they are taken. I think that building GPS system into cameras could be cool. This will help to store the location, direction and possibly the pitch and also will add more life to the pictures. By the way, it may be possible to create a 3D map using this technique in future.

It would be cool if our mobile phone or PDA beeped when there was our friend nearby. It seems to be possible using Bluetooth technology.

I would like my cell phone to have its display be adjustable. That way, when I want to read an SMS, I don't have to put my glasses to see the message. This idea could be applicable for any LCD device.

On my cell phone, I'd like a sensor which recognize my voice and automatically picks up the call if i say any particular word Like "hello" or "hey." Especially when I am driving or busy in kitchen. Also, it would be nice to disconnect the call using any word which has been already recorded in the phone sensors. We have seen cell phones with a touch screen. Now I'd like to see a phone which is only voice activated. It would really help people to drive safely and enjoy talking while...

When blind people go out for the day, they have no way of knowing who has visited their house. My idea is a combined doorbell where the visitor can leave a recorded message for the blind person when they return home.

On my cell phone, I'd like a button to press while I'm driving (could be part of the car-based charger) that would inform the caller that I'm driving and will call back when possible. Perhaps double-click this button to inform that than "I'm pulling over now/soon to call you" and single-click to inform "I will call later when I get a chance." The responses could be pre-recorded by the phone's owner.

When a teenager would rather downgrade to a less damage-prone cell phone than her iPhone, it gets me thinking. Why would a person rather deal with a feature-deficient version of a device? Because they value something different about that device. There is a whole class of cell phone users who want something the current crop of cell phones isn't addressing directly. They want dependibility, durability, reliability. It's become their lifeline of communication to their friends and they'd...

I would like to see a cellphone incorporate a virtual keyboard. With the phone turned to landscape mode with an added kickstand, it could give the needed angle to produce such an effect. It would be the ultimate full qwerty phone.

Why not incorporate a mini PIR into a phone. It could be enabled, for example, if you use your phone as an alarm to wake up. If you accidently press 'off' instead of 'snooze', the PIR would activate after a couple of minutes. If the PIR detected no activity (because you are asleep), the alarm could be activated again.. Then, you would never sleep through your alarm again! It could also be used for a proximity alarm, work through bluetooth etc etc
