Human Presence Detection & Management This Dell Whitepaper addresses the concept of non-intrusive human presence detection on commercial systems, with leverage towards consumer systems. It also summarizes key concepts of application of human presence determinations towards session & system management functionality.

Executive summary As Information Handling Systems (IHSs) become more intelligent, the ability to maintain or improve the key commercial tenets of Dell of most manageable, most secure and most intelligent without compromise becomes essential as a North Star Direction. A key aspect to this ability is the concept of the IHS being context-aware to attributes tied to user such as persona, compute usage, habits, and attributes tied to environment such as ambient brightness, location.

Introduction With the launch of the Dell Latitude 7400 2-in-1, Dell introduced the industry’s first proximity sensor based solution to accurately detect human presence in front of the PC, based on Intel Context Sensing Technology. As Information Handling Systems (IHSs) become more intelligent, the ability to maintain or improve the key commercial tenets of Dell of most manageable, most secure and most intelligent without compromise becomes essential as a North Star Direction.
Dell ExpressSign-In System Architecture Below is the high-level software architecture implemented to enable human proximity detection within the ExpressSign-In software application.
Wake on Approach (Near) : WOA Wake on Approach (WOA) provides a seamless method for user to wake their laptop up from modern standby sleep and login without physically interacting with the laptop. This experience allows for responsiveness and optimized time to productivity unseen by the market. Here is an outline of how this works: 1. 2. 3. 4. 5.
Dell ExpressSign-In Solution Details The solution works as a combination of the following processing elements to enable Dell ExpressSign-In behaviors: 1. Enhanced operating logic implemented within the Intel Integrated Sensor Solution 2. Intel Context Sensing Technology middleware software, and 3. Dell system BIOS Human presence detection is optimized to ensure that users are adequately detected and office objects do not inappropriately alert the HPD logic.

Wake on Approach (Near) Details Wake on Approach (WOA) is implemented in such a way that it will only wake the system when the system has a sufficient battery level. In order to provide the fastest response time, any new movement in front of the proximity sensor will initiate a wake from modern standby sleep state. This may introduce false wake events in a busy work environment or even possibly trigger detection when pets are around.
3. Does Dell ExpressSign-in have any sensitivity to ambient conditions such as light, heat et cetera? a. Yes, direct sunlight on the IR TOF sensor and/or certain ambient lighting conditions may affect performance. Please contact us for more information. Summary With the introduction of the human proximity detection solution, enabled by Dell ExpressSign-In, the foundation of modern experiences for IHSs is upon us.
