Abstract:
An example embodiment there is provided an electroluminescent device (10) comprising: an electroluminescent component (14), a first piezoelectric component (15), an alpha electrode (11 ) and a first beta electrode (12), the electroluminescent component (14) being located between the alpha electrode (11 ) and the first piezoelectric component (15), the first beta electrode (12) being in electrical contact with the alpha electrode (11 ) and in electrical contact with the first piezoelectric component (15), the alpha electrode (11 ), first beta electrode (12), first piezoelectric component (15), and electroluminescent component (14) being configured to generate a potential difference across the electroluminescent component (14) responsive to a mechanical stress applied to the first piezoelectric component (15).
Abstract:
An apparatus comprises an optically transparent electrode configured to provide transcutaneous electrical nerve stimulation to a user contacting a portion of an exterior surface of said apparatus proximal to said optically transparent electrode.
Abstract:
A user interface comprising a display arranged to display visual content and a tactile surface arranged to convey a tactile representation, wherein said tactile representation is based on said visual content. This has the advantage of enabling a user to perceive content being displayed to him with less cognitive effort.
Abstract:
A shoe insole (101,102) is provided with skin transducers (131,132,133) that are coupled to a controller which in turn receives suggestive activation signals via a wireless receiver (127). A profile associated with the music and containing suggestive activation signals corresponding to dance steps that are synchronized with said music are stored in the electronic device. The electronic device transmits the suggestive activation signals via a wireless transmitter to the receiver of the shoe insole. The activation signals assist the user in performing the correct dance steps in the rhythm with the song that is played on a music player in the electronic device. Transducers implemented in a shoe insole provide tandem operation stimulating and sensing. The sensing is used for sending back information about walking/dancing style. Such information is further analyzed and exploited for health and wellness applications and/or low-level low cognitive effort security applications
Abstract:
A mobile electronic device with a virtual input device. The virtual input device includes an optical sensor for detecting movement of a user's fingers over a work surface and an acoustic or vibration sensor, for detecting an impact of the user's fingers on the work surface. A processor, coupled to the optical sensor and to the acoustic sensor, processes the detected signals as input for the electronic device. The user's fingers can be shown on the display overlaid by a virtual mask. The virtual mask may show a keyboard of menu items.
Abstract:
In accordance with an example embodiment of the present invention, an apparatus comprises: a material attachable to skin, the material capable of detecting a magnetic field and transferring a perceivable stimulus to the skin, wherein the perceivable stimulus relates to the magnetic field.
