Perixx PERIBOARD-505H Wired Mini Keyboard with Built-in Trackball, 0.55 Inch Trackball and 2 USB Hubs, Black, US English Layout

La tastiera è ben costruita e funziona ottimamente. Per un uso professionale può far piacere sapere che il trackball è posizionato nell'angolo in alto a destra e si tratta di una sfera abbastanza piccola (inferiore alle dimensioni di una pallina dei vecchi mouse), con una velocità di rotazione elevata (cioè fa poco attrito). Questo consente spostamenti velocissimi del cursore.

Good keyboard. I wish they swapped the left alt and FN key. I wish the roller ball had a quick release to clean the dust. I wish it had a scroll wheel

Perfetta alle mie esigenze. Trovo utile anche il trackball in caso di emergenza, anche se continuo ad usare il mouse

トラックボール付きのものを探してたところ、こちらが安価で11inchタブレット用のバックにも入るサイズでしたのでこちら購入しました。初英字キーボードでキーの配置が若干違うことへの慣れ、日本語入力切り替えの設定変更など必要そうです。押し心地はなんというか90年代のパソコンに付属してたものに近いです。トラックボールは若干反応悪いです、ゆっくり転がすと動かないです。 たまにしか使わないので問題ないですが、メインで使おうという方にはトラックボールの反応の悪さがネックな感じします。

OK, so I am loving this keyboard in most ways. I love the dedicated numeric keypad, helpful as I test screen readers. I am typically a keyboard-oriented user, and the typing feel is definite, without mushiness. But the design of the trackball does pose challenges. I am not a big fan of trackball on the right, buttons on the left, but the placement of the right and left buttons is problematic, as others note. I am mostly wrapping my hand around the right corner and moving the ball with my thumb and pressing the left mouse button with my forefinger. The trackball isn't as sensitive as some others have commented, but the manufacturer may have responded to feedback. That wraparound technique is probably only manageable for someone with smaller hands, and it might not be manageable if the keyboard is in a drawer for rack-mounted systems, etc.. If I had larger hands, I could cup my hand over the numeric keypad and press the left mouse button with my forefinger and roll the ball with my middle finger. Overall, though, this keyboard is going to work best for people who aren't using a pointing device a lot. That being said, I like it better than the Adesso it's replacing. Kudos, too, for including an Applications key, when many keyboards omit them, which is hard on assistive technology users.
