An estimation device includes processing circuitry configured to acquire a pupil diameter of a subject whose work performance is to be estimated at a time of work and a luminance of a gaze target of the subject, calculate a variation amount of the pupil diameter of the subject from time-series data of the pupil diameter of the subject, determine whether or not the luminance of the gaze target of the subject is equal to or higher than a predetermined value, and determine that a correlation between a magnitude of the variation amount of the pupil diameter of the subject and a deterioration in the work performance of the subject is low in a case where it is determined that the luminance of the gaze target of the subject is equal to or higher than a predetermined threshold.

A task determination unit determines a type of processing being operated, on the basis of an operation situation of an existing system. A conversion unit converts voice data input during a predetermined operation of an HID into text data, and determines whether the text data is used for a command determination or a setting parameter according to operation content of the HID. A command determination unit determines a command by using the text data and the type of processing being operated, when it is determined that the text data is used for the command determination. An operation unit executes an operation corresponding to the determined command with respect to the existing system by using the text data as a parameter, when it is determined that the text data is used for the setting parameter.

An estimation device includes processing circuitry configured to acquire time-series data of a pupil diameter during work of a subject of work performance estimation, smooth the time-series data of the pupil diameter of the subject by a first time window, smooth the time-series data of the pupil diameter by a second time window that is a time window larger than the first time window, calculate a difference between time-series data of the pupil diameter smoothed by the first time window and time-series data of the pupil diameter smoothed by the second time window, and estimate a level of work performance of the subject based on a magnitude of the difference between the time-series data of the pupil diameter smoothed by the first time window and the time-series data of the pupil diameter smoothed by the second time window, and output a result of the estimation.

A user interface augmentation system includes a memory and a processor coupled to the memory. The processor is configured to perform operations including: searching a system screen for a base point UI serving as a base point for display of an additional user interface (UI) to be added to the system screen; displaying a new screen with a transparent background in such a way as to overlap the system screen; and displaying the additional UI at a position based on the base point UI on the new screen.

A debug information abstraction unit () of a proxy server () adds, when a predetermined rule of an extension program is embodied into a program, a program for outputting debug information regarding the predetermined rule to the embodied program. Then, a debug information transmission unit () of a terminal device () transmits, to a debug support device (), the debug information regarding the predetermined rule for which the program has been added.

A peripheral information acquisition unit () acquires information relating to a first application () running in a terminal, information relating to control of the terminal, or information that can be acquired from a sensor included in the terminal, as peripheral information. The peripheral information acquired by the peripheral information acquisition unit () is accumulated in a peripheral information accumulation unit (). A dialogue interface unit () accepts input of information from a user and outputs information to the user. When the peripheral information accumulated in the peripheral information accumulation unit () and information input to the dialogue interface unit () satisfy a predetermined condition, a scenario control unit () causes the dialogue interface unit () to output information relating to execution of a second application () that is associated with the condition in advance.

A storage unit stores a rule for specifying additional information to be displayed for each operation scene identified with a combination of states of DOM elements of a predetermined web page being represented by presence/absence or attribute values. A rule interpretation execution unit monitors the states of the DOM elements of the predetermined web page, and causes the storage unit to store the states as a context board. The rule interpretation execution unit displays, if states of the operation scene matching states of the context board stored in the storage unit, the additional information specified with the rule.

Attribute-based rules for displaying additional information

A setting unit () includes: a limitation unit () that limits a list of extension user interface items to be added to an existing Web system, the items being selectable by a setting person, according to a role of the setting person including affiliated post, skill, or authority of the setting person and user interface information; and an operation setting unit () that sets the extension user interface in which a parameter specifiable for the item selected by the setting person is limited according to the role of the setting person and the user interface information.
