Many embodiments may comprise logic such as hardware and/or code to implement user interface for traversal of long sorted lists, via audible mapping of the lists, using sensor based gesture recognition, audio and tactile feedback and button selection while on the go. In several embodiments, such user interface modalities are physically small in size, enabling a user to be truly mobile by reducing the cognitive load required to operate the device. For some embodiments, the user interface may be divided across multiple worn devices, such as a mobile device, watch, earpiece, and ring. Rotation of the watch may be translated into navigation instructions, allowing the user to traverse the list while the user receives audio feedback via the earpiece to describe items in the list as well as audio feedback regarding the navigation state. Many embodiments offer the user a simple user interface to traverse the list without visual feedback.

A system for controlling presentation of information to a user based on the user's current condition. In particular, the system monitors the user and the user's environment, and creates and maintains an updated model of the current condition of the user. The user condition can include a variety of condition variables, including abstract concepts such as the user's current cognitive load, desired level of privacy for output information, and desired scope of audience for output information. Upon receiving output information to be presented to the user (e.g., from an application program), the system determines an appropriate output device and an appropriate format with which to present the information to the user, and then presents the output information. The system can also receive description information about the output information that describes relevant factors for determining when and how to present the output information (e.g., the importance and urgency of the output information, the consequences of the user not receiving or ignoring the output information, etc.). Some versions of the system execute on a wearable computer having a variety of available output display devices.

The present invention extends to methods, systems, and computer program products for adjusting user interface elements. Embodiments of the invention can adjust the size, shape, and position of user interface elements and whitespace based on historical usage data. Adjustments can reduce the cognitive load associated with selecting some user interface elements. In dangerous environments, such as, for example, a moving vehicle, reducing the cognitive load allows a user to pay attention to other matters, such as, for example, safely operating the moving vehicle. Historical usage data can originate from one or more users and one or devices. Adjustment limits can be used to insure user interfaces remain appropriately usable. User interface element adjustments can be used to optimize a user interface and/or influence user interactions with a user interface.

A method of, and apparatus for, determining if a person operating equipment is experiencing an elevated cognitive load, wherein the person's use of a device at a first time is monitored so as to set a baseline signature. Then, at a later time, the person's use of the device is monitored to determine the person's performance at the second time, as represented by a performance signature. This performance signature can then be compared against the baseline signature to predict whether the person is experiencing an elevated cognitive load.

This invention concerns a method for measuring cognitive load of a person in performing a task. In other aspects the invention can be expressed as a computer and as software that are used to perform the method. The computer (50) has an interface having a plural number of unimodal input (20, 30 to 40) and output devices, and a cognitive load analyzer (50). The analyzer comprises a receiver to receive input data signal streams (25, 35 and 45) from respective devices (20, 30 and 40). A classifier (56 to 59), (66 to 69) and (76 to 79) is also provided to identify predetermined “meta-interaction patterns” from the streams (25, 35 and 45), and to weight the identified predetermined “meta-interaction patterns” to produce respective weighted outputs. A combiner (80) to fuse the outputs to produce a measure indicating the person's cognitive load.

This invention concerns measuring cognitive load. A word based input is produced by a person while performing a task (100). Predetermined grammatical features of the word based input are identified (104). Then, the identified grammatical features are weighted and combined to provide a measure indicating the person's cognitive load (106). The use of grammatical features represents a divergence from the known methods of providing a measure of a person's cognitive load. It is an advantage of the invention that by concentrating on the grammatical features it is able to provide an objective, non-intrusive measure of the person's cognitive load. Aspects the invention include a method, a computer system and software that are used to perform the method.

A technique for stylus-based syllabic input that is fast and easy and does not require any additional hardware and can be deployed on a handheld device is described. In one example embodiment, this is accomplished by writing a base syllabic character consisting of a vowels or consonant in a writing area. One or more modifiers that are displayed as icons substantially around the writing area of a syllabic level user interface are then selected to form a desired syllabic character. The one or more modifiers are arranged at familiar/natural positions around the base character's writing area to facilitate entry/selection of modifiers and to reduce eye movement/cognitive load on the user. The syllabic characters are then accumulated locally until a desired word is formed, to reduce visual disconnect between the input interface and the end application, and to provide context for formation of the desired word. Further, one or more hypothesis words are then presented to speed up the formation and inputting of a desired word. The formed desired word is then cleared from the display area and sent to an application display area by tapping a space button provided in the syllabic character input user interface.
