Installation of suitable drivers helps to resolve this issue. While rebooting the system, the keyboard is not supported and hence the users may face an issue. Universal Serial Bus Keyboard has a USB stick with a wire which has to be inserted into the USB port of the system. There is no physical object to carry for a virtual keyboard. Also in the windows system, we can use a virtual keyboard that appears on the screen. This can be automatically set as per need. This keyboard appears when needed and disappears when typing is completed. The keyboard used in smartphones is called a virtual keyboard. Transmitter sends the strokes from the keyboard as radio waves which are received by trans-receiver kept near parent device. These keyboards should have a transmitter and trans-receiver. These keyboards are lightweight and smaller in size. We can port the keyboard and the parent system is not needed near the keyboard. Wireless Keyboardīluetooth, IR technology or Radio Frequency is used to connect the keyboard with the computer device. A button is pushed down and an electrical signal is sent to the computer device which then shows the characters. The primitive keyboard which uses physical buttons for each key is called a mechanical keyboard. Also, a button to launch a browser, my computer, calculator is available. The buttons include play, pause, previous, next, volume up, volume down, mute and special button to launch media. You can now bind/subscribe to usingMouse() & usingTouch() and/or style your interface with the body.mouse class.The keyboard that has all multimedia buttons is called multimedia keyboard. See the following options: /* The primary input mechanism of the device includes a The pointer media feature is used to query the presence and accuracy callback is called when the result of "hasMouse()" changes.Īs of 2018 there is a good and reliable way to detect if a browser has a mouse (or similar input device): CSS4 media interaction features which are now supported by almost any modern browser (except IE 11 and special mobile browsers). callback is called when the result of "hasTouch()" changes. Level 2 (I don't think it's possible, but maybe I'm wrong, so why not asking) I don't think we have this in the answers already, that why I offer a bounty Note: as explained by the OP, this is not !hasTouch() The current answers provide a way to do that. To make the need more clear, here is the API that I'm looking to implement: // Level 1 For devices with mouse and touch, it should return false (not touch only)Īs a side note, my touch interface might also be suitable for keyboard-only devices, so it's more the lack of mouse I'm looking to detect. The code that correctly answers the question should return false if the device has a mouse, true otherwise. The touch event capability in the browser doesn't actually mean the user is using a touch device (for example, Modernizr doesn't cut it). How can I detect that my user has no mouse to present him the right interface? I plan to leave a switch for people with both mouse and touch (like some notebooks). I'm developing a webapp (not a website with pages of interesting text) with a very different interface for touch (your finger hides the screen when you click) and mouse (relies heavily on hover preview).
