Abstract: User interface control using a keyboard is described. In an embodiment, a user interface displayed on a display device is controlled using a computer connected to a keyboard. The keyboard has a plurality of alphanumeric keys that can be used for text entry. The computer receives data comprising a sequence of key-presses from the keyboard, and generates for each key-press a physical location on the keyboard. The relative physical locations of the key-presses are compared to calculate a movement path over the keyboard. The movement path describes the path of a user's digit over the keyboard. The movement path is mapped to a sequence of coordinates in the user interface, and the movement of an object displayed in the user interface is controlled in accordance with the sequence of coordinates.

Abstract: A wearable sensing band is presented that generally provides a non-intrusive way to measure a person's cardiovascular vital signs including pulse transit time and pulse wave velocity. The band includes a strap with one or more primary electrocardiography (ECG) electrodes which are in contact with a first portion of the user's body, one or more secondary ECG electrodes, and one or more pulse pressure wave arrival (PPWA) sensors. The primary and secondary ECG electrodes detect an ECG signal whenever the secondary ECG electrodes make electrical contact with the second portion of the user's body, and the PPWA sensors sense an arrival of a pulse pressure wave to the first portion of the user's body from the user's heart. The ECG signal and PPWA sensor(s) readings are used to compute at least one of a pulse transit time (PTT) or a pulse wave velocity (PWV) of the user.

Abstract: A set of reconfigurable clip-on modules for mobile computing devices includes two or more modules and at least one of the modules has an input button or other control and at least one of the modules can communicate with the computing device without needing to be connected to it via a wire. The input button is mapped to a user input in a program, such as a game, which is running or displayed on the computing device to which the modules are clipped. In an embodiment, user inputs via the buttons or other controls on the clip-on modules are mapped to user inputs in a game running on the device, which may be a touch-screen device, and the mapping between user inputs via the buttons and user inputs in the game may change dependent upon the game being played, user preference, or other criteria.

Abstract: A system for generating custom modular objects is described. The custom modules form part of a modular construction set from which an object can be created by a user. The object acts as a user input device for an interactive software experience. To generate a custom (i.e. non-standard) module, a virtual 3D shape is received by a module generation service. The service converts this shape into a derived 3D shape for the module, for example, ensuring that the module is shaped such that it is compatible with other modules from the modular construction set to which it will be connected for form an object and/or by adding an aperture for receiving a connector and/or electronics core. Once generated, the derived 3D shape is sent to the user in physical form or virtual form and a virtual representation of the module is provided to the interactive software experience.

Abstract: A building block is described which has a plurality of faces each with an associated coupling element, such that a first coupling element is adjacent to a first face and a second coupling element is adjacent to a second face, etc. An RF switch in the block is arranged to selectively couple two of the coupling elements together under the control of a processor. The processor controls the RF switch in response to signals received from a transceiver module. A sensing and switching arrangement within the building block selectively connects the processor to one of the coupling elements based on a detected orientation of the block (e.g. so that power harvested from the transceiver module can be used to power the processor). The coupling elements are either all antennas or all electrodes.

Abstract: A pointing device using proximity sensing is described. In an embodiment, a pointing device comprises a movement sensor and a proximity sensor. The movement sensor generates a first data sequence relating to sensed movement of the pointing device relative to a surface. The proximity sensor generates a second data sequence relating to sensed movement relative to the pointing device of one or more objects in proximity to the pointing device. In embodiments, data from the movement sensor of the pointing device is read and the movement of the pointing device relative to the surface is determined. Data from the proximity sensor is also read, and a sequence of sensor images of one or more objects in proximity to the pointing device are generated. The sensor images are analyzed to determine the movement of the one or more objects relative to the pointing device.

The data store comprises a number of records, each record relating to a physical module in the modular assembly system and comprising a module ID, an owner ID for the module and one or more properties fields.

The data store communicates with the interactive software experience and causes a change in behavior of the interactive software experience in response to a check of the data records for each of the modules in the object.

Abstract: 3D printing may be optimized by segmenting input jobs and/or combining parts of input jobs together. In an embodiment, a user-defined metric is received associated with each input job and this is used in scheduling input jobs to optimize latency and/or throughput of the 3D printing process, along with the printing envelope and other characteristics of the 3D printers used.

In various embodiments, the scheduling is repeated when a new input job is received and changes made during printing. In various embodiments, a user may submit an updated version of an input job which is already in the process of being printed.

Abstract: An interactive computer game is described which works in conjunction with a number of physical modules that a user can connect together in different ways to form a coherent physical whole object. The game receives data from the object via a wireless link, the data identifying at least which modules form part of the object and updates game play based on the data received. At some point within the game play, the game presents an objective or goal to the user which the user can only achieve by interacting with the physical object formed from the modules. In an embodiment, this interaction comprises re-arranging the modules or swapping modules to form an object with a different visual appearance, moving all or part of the object and/or interacting with a sensor on a module in the object. The game may receive further data from the object during the user interaction.
