FIGURE 5. — Frame Rate and Battery Life Evaluation The ĒLVIS rendering performance was evaluated by simulating an EAMS with pre-recorded case data. (a) The largest models from 4 recorded cases were played back at 1Hz to simulate the expected worst-case processing load and model complexity. Catheter positions were updated at the nominally expected 20Hz. (b) Resulting frame rate distributions are shown for each case with median values represented by white circles. The average frame rate across all simulations was 53.5± 5.4 frames per second. Battery life was evaluated using an EAMS simulation with logger that was connected to the normal ĒLVIS undergoing testing. (c) The HMD was then attached to either an external battery and a network-controlled relay that allowed the test fixture to cycle the devices through charge and discharge cycles. A recorded electrophysiology case was then simulated repeatedly through the EAMS simulator at either normal playback speed or at the maximum network throughput for stress testing. (d) Battery testing performed on four HMDs across 7 discharge cycles; X’s show the distribution, white circles show mean values.
