Abstract: A system including sensors configured to provide physiological markers of a developer and a controller configured provide information indicative of a user experience to the developer while receive signals from the sensors. The controller is configured to utilize cognitive analysis determine developer emotion responses as the developer receives the user experience. The controller compares a developer emotion classification with a user emotion classification of a user as the user generated the user experience. The system generates a prioritized backlog to identify points where emotion responses between user and developer are in common, or where emotion responses between user and developer differ.

Abstract: Methods, computer program products, and systems are presented. The method computer program products, and systems can include, for instance: obtaining first building event transaction data of a building using a first data source; recording a first blockchain block in a blockchain ledger, the first blockchain block having a timestamp and the first building event transaction data; obtaining second building event transaction data of the building using a second data source; recording a second blockchain block in the blockchain ledger, the second blockchain block having a timestamp, and the second building event transaction data; examining data of the first blockchain block and the second blockchain block; and providing one or more output in dependence on the examining.

Abstract: An approach is provided for optimizing a digital display. Classifications of advertisements are determined. A location of a future action in an event is predicted. A sentiment of an audience is determined. The audience includes spectators at the venue, viewers who are viewing the event via devices receiving a live broadcast of the event, or a combination of the spectators and the viewers. Based on the location of the future action, a digital display is selected from digital displays in the venue and content on the digital display is predicted to be captured as an image by a camera and broadcast to devices of the viewers. Based on the classifications, the sentiment, the location of the future action, and the content being predicted to be captured and broadcast, an advertisement is selected. The selected advertisement is sent to the selected digital display.

Abstract: An approach is disclosed that optically transmit data from a dedicated mobile device (DMD) to another device. Optically transmitting the data is performed by displaying the data on a display screen included in the DMD. The approach further optically receives data at the DMD. The data is received at a digital camera included in the DMD. Based on the exchanged data, the DMD determines if the DMD and the other device are bound to each other.

Abstract: An approach is disclosed that places a first side of an optical communication mounting frame (OCMF) onto a surface of a device with some of the device's display and its digital camera being are hidden from view from outside of the OCMF. A second device is received at another side of the OCMF, with some of the device's display and its digital camera being are hidden from view from outside of the OCMF. Each display is viewable from the other device's digital camera. Optical communications between the devices is performed by displaying data on one display that is read by the other device's digital camera and this communication is allowed while the OCMF is present. However, communication between the devices is inhibited when the OCMF is not present.

Abstract: An approach is disclosed that optically transmits a data from an information handling system that is a Stand Alone Certificate Authority (SACA) device, to a dedicated mobile device (DMD). The optically transmission is performed by displaying the data on a display screen included in the SACA device. The approach further optically receives data from the DMD by reading data displayed on the DMD's display screen using the SACA device's digital camera. Based on the data transmitted and received, the system verifies that the DMD and the SACA device are bound to each other.
