(1) The most fundamental requirement of a mattress is to provide a comfortable sleeping experience. Many smart mattress products are developed by first designing sensor technology and then seeking mattress manufacturers for integration. However, WhizPad takes a completely different design approach. From the beginning, it was developed in collaboration with Wellcare, a premium Taiwanese mattress manufacturer. Unlike traditional smart mattresses, WhizPad contains no electronic components inside the mattress itself. Instead, Wellcare's high-quality foam material is engineered into a pressure-sensitive sensing layer, seamlessly integrated into the mattress. Beyond its smart capabilities, WhizPad ensures exceptional comfort, conforming to the user’s body shape for optimal support and pressure relief. Clinical research conducted by a leading Taiwanese medical center has demonstrated that WhizPad significantly reduces the incidence of pressure injuries, with results published in an international journal. According to the 2022 Taiwan Patient Safety Reporting System Annual Report, falls were the second most reported hospital safety incidents (22.2%, second only to medication errors). Among hospital patient falls, the most common activity at the time of the incident was "getting in and out of bed" (20.9%). Traditional bed-exit alarms are often used for fall prevention, but these typically have a small coverage area, leading to false alarms. Additionally, caregivers are often alerted only after the patient has already left the bed, making timely intervention difficult. WhizPad’s smart functionality is designed to address this issue at its core. As shown in Figure 3, the entire mattress is embedded with 30 pressure-sensing zones (5×6 grid). Using machine learning algorithms, WhizPad can accurately determine the user’s bed posture, detecting whether they are lying down, sitting up, sitting at the edge, or if the bed is empty. Through an IoT framework, real-time posture data is displayed on nursing station monitors or mobile apps. To further enhance fall prevention, WhizPad includes a three-stage voice alert system, triggering progressive bed-exit warnings (sit-up, edge-of-bed, and bed exit). This allows caregivers to anticipate patient movements and provide timely assistance, reducing the risk of falls before they happen.

(2) WhizToys is a modular, interlocking activity-sensing mat that can be assembled into various shapes, such as a basic 3×3 grid or an expanded 9×3 sports field layout. WhizToys connects to an app via Bluetooth, allowing users to engage in cognitive training, physical activities, competitions/cooperative games, and functional assessments simply by walking or stepping on the mat. The game app provides a multi-sensory experience through visuals, lights, and music. Caregivers or trainers can customize the game type and difficulty level based on the user’s condition and abilities. Additionally, the app serves as a customizable game development platform, enabling modifications based on personal experiences and cultural backgrounds. The app also features account login functionality, storing gameplay results in the cloud for future evaluation and analysis.

The product is designed around three key principles:
1. Multifaceted interaction, integrating exercise, cognition, social engagement, and multi-sensory stimulation.
2. Customizability, allowing users to select or design games that suit their needs, experiences, and difficulty levels.
3. Meaningful data generation, recording valuable medical and healthcare-related insights through gameplay.
