I know that tapping on the screen with an object doesn't cause any reaction in the user interface (e.g. it doesn't cause a click of a button shown from an application). To what is the iPod's screen sensitive, and what can I use to replace my fingers?

The problem I am trying to resolve is that, using my finger to play a game, I don't see part of the screen, and my finger hits something that causes the game to end (you know, those little bombs that are launched in the play field when you are trying to slice fruits).

香腸非常好用! (不是在開玩笑)

現在,我是否應該說你的手指比香腸大? `:-)`
其實我不知道你的手指:-p
噢,哎呀,即使是憂鬱症也比我的手指(我的拇指除外)更大。 `:-)`
因此,請接受它作為戴手套使用iDevices的提示。
香蕉更好地工作。

Something conductive and either soft or flat will register with the capacitive touch screen sensors. A ball of conductive foam or wadded up aluminum foil, or even a half inch strip of the metallic insides of a power bar wrapper.

There are several manufacturers of iPhone stylus's that use variations of the above. You can google them.

Non-conductive stuff won't work. And anything too pointy will also have problems being recognized, as there won't be sufficient electrical field coupling.

沿著這些線條,水是導電的,這就是為什麼如果在雨中使用屏幕或手濕的話,屏幕可能會彎曲的原因。

到目前為止,所有答案都有些不准確或含糊。更詳細的答案:

Apple的觸摸屏設備和触控板使用電容式觸摸屏感應。該技術可測量點網格上的電容。當達到人體皮膚某個閾值內的電容時,軟件會對在屏幕上這些點處檢測到的觸摸輸入做出反應。

例如,與電阻式觸摸屏相反,電阻式觸摸屏通常用於較舊或較低端的電子產品。它們在表面上有輕微的糊狀感覺,並且比電容式屏幕的響應性要差得多,但是可以與任何物體一起用作手寫筆。這通過具有兩層導電柵線來實現。當物體在表面上造成凹陷從而將兩層推到一起時,可以通過比較各個網格線的電阻來測量接觸點。

進行了這種區分,用於交互的任何物體電容式觸摸面板的電容必須具有與皮膚相似的電容。諸如肉之類的東西會起作用(建議使用香腸),但不是很實用。但是,可以在網上輕鬆找到專門用於這些屏幕的筆。這些對您來說可能是完美的解決方案,因為它們就像用於觸摸屏的細長筆一樣,不會像胖拇指那樣遮擋您的視線。

任何會產生電場的東西。您的手指會產生電場,因此會在屏幕上產生“喀噠”聲。 這裡是iPhone觸摸屏上的好文章。

不完全是-您需要電壓差才能產生電場。您的手指沒有,所以不會產生電場。而是,屏幕實際上包含一個電容器陣列,並且如果您的手指靠近這些電容器之一,它將改變該電容器的電容。可以檢測到該更改。

來自Wikipedia:“專為電阻式觸摸屏設計的手寫筆不會在電容式傳感器上註冊。需要在主要用於手指的電容式觸摸屏上工作的手寫筆才能模擬人類手指所提供的電介質差異。[11]”
