電腦鍵盤再進化。從Apple 最新獲證專利,一種Fusion Keyboard鍵盤,就是將傳統鍵盤和觸控板二合為一,每個按鈕都有觸控感應。換句話說,除了按下按鍵打字,還可以在按鍵上做出操控手勢。而且,每個按鈕都有兩層。按下第一層是普通打字,再用力一點按到第二層就變成滑鼠點擊。
 
美國專利商標局(USPTO)2015年5月26日通過一項蘋果在2011年申請的“聚合鍵盤”的新專利US9041652 B2 (Fusion Keyboard)。專利中描述了配備電容式觸摸感測器的設備,以及可按壓的機械按鍵,支援多層級按壓。由於鍵盤的按鍵採用了觸摸感應表面,這種特殊的鍵盤可以檢測手指手勢,比如輕按和滑動,就像 MacBook 的觸控板。
 
這些鍵盤按鍵收集的操作可以在螢幕上實現滑鼠指標移動的操作。比如,使用者可以通過在鍵盤上滑動完成滑鼠的選擇、點擊、滾動、拖拽、縮放等其他操作。
 
這種鍵盤解決方案可以移除觸控板,將觸控板功能與鍵盤集成在一起,進一步減少電腦尺寸。(605字;表1)
 
表一、US9041652 B2 (Fusion Keyboard)請求項1

1.        A keyboard comprising:

a plurality of depressible keys, wherein at least one key of the plurality of depressible keys is a   dual-purpose key configured to be depressed   a first distance to a first level   and   a second distance to a second level;

a plurality of switch sensors configured to detect a depression of a key of the plurality of depressible keys, wherein at least one switch sensor of the plurality of switch sensors is configured to detect the at least one dual-purpose key being depressed the first distance to the first level and the at least one dual-purpose key being depressed the second distance to the second level;

an array of   capacitive sensors   configured to detect a touch event on a surface of one or more of the plurality of depressible keys; and

a processor configured to:

receive a touch event signal indicating that the touch event has been detected by the array of capacitive sensors on the surface of the one or more of the plurality of depressible keys;

receive a key depression signal indicating that the depression of the key of the plurality of depressible keys has been detected by at least one of the plurality of switch sensors;

generate a   key depression command signal   in response to receiving the key depression signal; and

generate a touch event command signal in   response to   a threshold length of time elapsing from receiving the touch event signal without receiving the key depression   signal.

結構上 :

鍵帽下方有電容偵測層 ,

至少一顆按鍵有兩段按壓深度 , 兩種按壓深度分別代表兩種輸入訊號

 

claim1 描述的運作 :

(1)“ 只偵測到觸摸鍵帽 , 且未偵測到鍵帽按壓 ” 時間超過一預設時段 -> 判定為觸控

(2) 偵測到鍵帽按壓第一距離 -> 判定為按壓輸入第一訊號

(3) 偵測到鍵帽按壓第二距離 -> 判定為按壓輸入第二訊號
